What are the different types of nuts available?
Our nuts come in many styles to suit diverse applications. Here are some of the main types we offer:
 | Acorn Cap Nuts: Acorn cap nuts, often referred to as dome nuts, are a popular choice for those seeking both visual appeal and practicality in their projects. These nuts sport a distinctive design with a domed top that not only adds a polished finish to joints but also shields the external threads of the male fastener from potential harm and environmental wear. Installing and removing acorn cap nuts is a breeze, requiring only a hand wrench or manual effort. Our extensive range includes sizes from #4-40 to ¾”-10, catering to various needs. You'll also find these nuts available in an array of materials, including 304 and 316 stainless steel, A2 stainless steel, nickel-plated steel, chrome-plated steel, and brass, ensuring compatibility with your specific requirements. Discover the perfect balance of aesthetics and functionality with our acorn cap nuts. |
 | High Crown Cap Nuts: High crown cap nuts, a variant of classic acorn nuts, take elegance and adaptability to new heights. With an extended domed top, these nuts accommodate a greater protrusion from the male fastener, ensuring a refined and finished appearance. You can choose between rounded dome top and flat top designs, both featuring internal threading. Our offerings cater to diverse needs, ranging in size from a compact ⅜”-16 to a substantial ½”-13, with various length options for added versatility. These high crown cap nuts are exclusively crafted from durable 18-8 stainless steel, ensuring resilience and longevity. Elevate your projects with the perfect blend of aesthetics and flexibility offered by our high crown cap nuts. |
 | Extra Tall Acorn Nuts: Extra tall acorn nuts, with their exceptionally tall domed tops and deep internal threading, strike a harmonious balance between traditional acorn cap nuts and their extra tall counterparts. The heightened crown of these nuts surpasses the standard acorn nut while maintaining a slightly lower profile compared to the extra tall version. The crown or dome of these nuts features internal threading, making them a preferred choice when aesthetics and a polished appearance are paramount. Available in a range of sizes from as small as #10-24 to a substantial ½”-13, these nuts are exclusively crafted from durable 18-8 stainless steel. Elevate your projects with the enduring quality and American craftsmanship of our extra tall cap nuts, proudly Made in the USA. |
 | Extra Tall Flat Cap Nuts: Extra tall flat cap nuts, akin to extra tall acorn nuts but with a distinctive flat cap, are your ideal choice when aesthetics and corrosion resistance are paramount in your design. Crafted in the USA from robust 18-8 stainless steel, these nuts are available in a variety of sizes ranging from ⅜”-16 to ½”-13, with different length options. This versatility sets them apart from standard acorn nuts and high crown nuts, which typically come in a single standard length. With these extra tall flat cap nuts, you have the freedom to tailor your fastening solutions to your specific needs. Trust in the quality of American craftsmanship for your projects; all extra tall cap nuts from Albany County Fasteners are proudly Made in the USA. |
 | Coupling Nuts: Coupling nuts, sometimes called extension nuts, hex standoffs, or long nuts, serve a clear purpose: joining male fasteners together. These nuts, resembling elongated hex nuts with a threaded hole, are most commonly employed to connect threaded rods. Utilizing coupling nuts is a straightforward process, much like using standard hex nuts. They are designed to connect fasteners of the same size, often extending shorter threaded rods to create more extensive rod assemblies. You have a variety of materials to choose from, including 304 and 316 stainless steel, hot-dip galvanized steel, zinc-plated steel, and aluminum, ensuring compatibility with your specific needs. |
 | Coupling Reducer Nuts: Coupling reducer nuts, akin to standard coupling nuts, fulfill the role of joining male threaded fasteners. The distinction lies in their ability to connect fasteners of varying sizes. Beyond this, their operation and intent remain consistent with that of regular coupling nuts. Installing coupling reducer nuts mirrors the process of using standard hex nuts and is employed to extend shorter threaded rods into more extensive rod assemblies. Please note that our coupling reducer nuts are exclusively available in zinc-plated steel, serving your threaded connection needs with quality and reliability. |
 | Hex Flange Nuts: Hex flange nuts, a unique variation of the traditional hex nut, boast an integrated wide flange that serves as an inbuilt washer. This ingenious design spreads the applied load across a broader surface area, safeguarding your assembled components from potential damage. Hex flange nuts find their niche when used alongside softer materials in your projects.. There are two distinct varieties of hex flange nuts to cater to your specific needs. Serrated flange nuts feature a serrated face on the flange, enhancing their grip by "biting" into the assembly. This locking effect is particularly valuable in applications prone to vibration-induced loosening. On the other hand, non-serrated flange nuts excel in scenarios where expediency or the even distribution of loads is the priority.. Our serrated hex flange nuts are available in 304, 316, and A2 stainless steel, as well as zinc-plated steel. Meanwhile, our non-serrated flange nuts come in 304 stainless steel, 316 stainless steel, A2 stainless steel, zinc-plated steel grade A, and zinc-plated steel grade C, providing a comprehensive selection to meet your project's demands. |
 | Hex Jam Nuts: Hex jam nuts, akin to their standard hex nut counterparts, differentiate themselves primarily through their slim profile. These nuts, also known as thin nuts, measure approximately two-thirds the thickness of a standard hex nut and are engineered to serve as effective lock nuts. One of the key applications of hex jam nuts is to complement another nut, locking its position when the second nut isn't secured against another component. For example, when paired with a standard nut, hex jam nuts excel at anchoring an item to a fastener without exerting force on the item itself. Here's how it works: initially, you tighten a standard nut onto the component to be assembled. Then, you secure the hex jam nut on top of the first nut. Subsequently, you loosen and re-tighten the first nut against the second nut. This ingenious mechanism curbs axial movement and indentation in your assembled components while preserving their ability to rotate, making them ideal for applications like bearing installations. Moreover, hex jam nuts can step in for standard hex nuts in situations where the latter wouldn't fit. Our inventory includes hex jam nuts crafted from various materials, including 18-8, 316, and A2 stainless steel, zinc-plated steel, brass, and silicon bronze, ensuring you have the right nut for the job. |
 | Hex Nuts: Meet the workhorse of the nut world, the standard hex nut. With its hexagonal exterior body, this nut reigns as the most ubiquitous and versatile in its category. It's offered in a wide array of sizes, ensuring compatibility with bolts of various dimensions. Thanks to its exterior hex shape, you can effortlessly install it using standard tools like a wrench, socket, torque wrench, or nut driver. Our inventory boasts hot dip galvanized standard hex nuts, available with either fine (UNF) or coarse (UNC) threads, spanning from as small as ¼”-20 to as grand as 3”-4. It's important to note that for these nuts, it's advisable to pair them exclusively with hot dip galvanized male fasteners. This safeguards against corrosion and upholds the integrity of your joint by preventing the use of dissimilar metals in the connection. Explore the plethora of materials we offer for your standard hex nuts, including 18-8 Stainless Steel, 316 Stainless Steel, Zinc Plated Steel, Plain Alloy Steel, Silicon Bronze, Hot Dip Galvanized Steel, Brass, Aluminum, Chrome Plated Steel, and Black Chrome Plated Steel. Rest assured; you'll find the perfect standard hex nut for your project within our diverse selection. |
 | Knurled Thumb Nuts: Introducing knurled thumb nuts, the ultimate in hassle-free installation. These circular gems boast an exterior surface with a unique knurled pattern that lets you tighten or loosen them by hand. No tools needed! Perfect for those moments when aesthetics matter most or when you need a quick, adjustable fastening solution. Our knurled thumb nuts are available in 18-8 Stainless Steel and Brass, ensuring you have the right touch of style for your project. |
 | Machine Screw Nuts: Meet your go-to nuts for machine screws! These hex finish nuts are specially designed for screws with diameters under 1/4". They're just like standard hex nuts but compact, making them a perfect fit for smaller projects. Use them when your screws extend beyond a threaded hole, especially if that hole isn't pre-threaded. Our machine screw nuts come in various materials, including 18-8 Stainless Steel, 316 Stainless Steel, Brass, Zinc Plated Steel, Black Oxide Stainless Steel, Silicon Bronze, and Plain Alloy Steel, giving you options for any job. |
 | Small Pattern Machine Screw Nuts: When space is tight, reach for small pattern hex machine screw nuts! These nuts are just like standard machine screw nuts but designed for confined areas. They have a smaller wrench size, making them perfect for tight spots. Small pattern machine screw nuts come in 18-8 Stainless Steel and Zinc Plated Steel options, so you're covered for any space-constrained job. |
 | Square Nuts: Square nuts, with their four sides, offer more contact area with your components, ensuring a secure hold that won't easily loosen. While they resist loosening effectively, they may require more effort to tighten. Square nuts are commonly used alongside square-headed bolts and flat washers. Find them in various materials, including 304 and 316 stainless steel, zinc-plated steel, and hot dip galvanized steel. |
 | T-Nuts: T-nuts, also known as tee nuts or barrel nuts, are perfect for softer materials like wood and plastics. Shaped like a "T," they feature an internally threaded bore with prongs that firmly grip the material when joined with a male fastener. This ensures a secure connection that's unlikely to come loose. Most T-nuts have either 3 or 4 prongs, which reduce the risk of material splitting or cracking. Ideal for furniture assembly, T-nuts are available in 304 and 316 stainless steel, as well as zinc-plated steel. |
 | Wing Nuts: Wing nuts are a unique type of nut featuring two outwardly extending wings, allowing effortless hand-driven installation and removal. They find common use in applications where joints require frequent adjustments or when a non-permanent connection is needed. Some wing nuts come with flanged bodies, enhancing contact with assembled components. Available in various materials such as 304, 316 stainless steel, A2 stainless steel, zinc-plated steel, brass, and zinc alloy. |

All About Cap Nuts: High Crown, Too Tall, & Standard Nuts |
All About Cap Nuts TranscriptScroll Down To Continue Reading Bob: Welcome back to Albany County Fasteners, Fasteners 101. I'm Bob and today we're going to discuss high crown and too tall cap nuts. So let's get started. I have cap nuts here. I have a standard cap nut that you'll find almost anywhere. I have what they call a high crown and you can see, the crown's a little higher. It's probably somewhere about, I would say about, a heavy 3/8 of an inch taller than a standard cap nut. Then we have too tall. We have a too tall in a flat head and we have too tall in a rounded head. Now the two tall come fully threaded all the way through the inside to the top. So you have full threads all the way through. You have on the too tall what they call a flat top. You can see the top is flat and it has a chamfered edge around it and on the round the top is just rounded over like the standard cap nut at the top. They call these too tool because they're approximately, if you took the high crowns, double the height almost. But if you had two high crowns, I don't have two high crowns here but if I did, it would be close to this size and that's why they call it a too tall. These are USA made products, they're made here in the USA. They're quality products. These are 18-8 stainless steel. They're available on our shelf ready to ship. The question always comes up "what do I use for different things"? Depends on your application. So many different applications out there. How far is your threaded bolt sticking out on the other end? If it was sticking out that much, you couldn't use a standard cap nut. You're going to see probably about a 1/4" - 3/8" of an inch sticking out. If that was the application. So, then you would go to the high crown. I'll just keep my finger there as a stop, and that just makes it. Those are the different applications. This one, which is double tall, will keep on going and, just so you know, you will get some gulling because the difference here with stainless steel is that you have a rolled thread on the bolt and on the actual cap nut you have cut threads. So you have two different threads running against each other which creates gulling. You can use some lubricant. That works well. I just want to show you on this how far this will go in. So you're looking at a good 1-1/2" of this 2" bolt, that I have here. It'll go all the way in to this cap nut and there it is. As far as applications go, there are many different applications. I've seen these used for - they get polished up - some people will take them and polish them up. Polished stainless is amazing - the way it looks. They'll take them and put them on their trucks and their cars just for the look. It's all dependent on application. Here at my packaging machine, I want to demonstrate to you how they incorporated a cap nut. This is a standard cap nut. This is the bowl where the fasteners go in. This is a feeder and they used a cap nut, at the top, along with a lock washer to hold this cone in place so the fasteners don't build up and around the center of the machine. Here they used a standard cap nut with a lock washer to hold this cone in place. You could also, in this application, use any of them. Here's a high crown, that works on there, and here's a double tall. You can use that on there. This is actually a lot easier because sometimes the small little fasteners that we put in this machine, they get underneath this cone a little bit. They jam under there and you have to take this off. That's why they make it so you can screw it off with your fingers. I just used the top round one. That's pretty cool looking, but functionally it doesn't matter. The standard that comes with the machine, you can see here, the standard cap nut, finishes it off nice. Nothing can build on top during fastener jobs. Little fasteners, like a two point five millimeter falling on top won't stay on top of this nut. It just falls off and that's just the design. I just wanted to show you on my packaging machine how that could be applied. |
How to Use Hex Jam Nuts |
Using Jam Nuts TranscriptScroll Down To Continue Reading Bob: This is what they call a jam nut. Jam nuts are about half the size of a regular finish nut in height. Otherwise the circumference and everything else is the same; they use the same wrench to apply the nut and to remove the nut. Jam nuts, just to give you an idea what these do, you use two nuts together and then you tighten them up against each other. That's why they call them jam nuts: you use them together, you tighten them up, and I'll show you. I'll do a demonstration of that also, but typically that's how they're used. They're also used in tight areas where you can't have a full-size nut. So I'm going to demonstrate the installation of the jam nuts that I have here. I have two of them. Jam nuts are also called thin nuts. The difference is that they're about half the size of a regular nut. You can see that here. I'm going to put the first one on and then I'm going to put the second one on. I'm going to use an adjustable wrench to grab the bottom nut. Then I'm going to use the ratchet on the top to tighten it up. Now I'm tightening them up against each other. That's one of the reasons why they call them jam nuts. Jam nuts are also available in nylon lock nuts where you don't have to use this situation. Obviously jam nuts can be used in many different applications such as if you have a tight area like in a car application where you don't have the room to use a regular sized nut. They'll use jam nuts or a single jam nut to get on the back of an alternator for a bracket; something along those lines. They also use the nylons in that situation. So there's many different situations that you can use this in. They also sometimes want to put a jam nut like this to wherever it's keeping in place. They want this whole mechanism to be able to turn and move because they might be a moving arm on this bolt holding it in place. They also are used with shoulder bolts. So you'll find jam nuts used with shoulder bolts a lot on mechanical equipment. However you should know that if this is being used in a vibrating machine or something along those lines, these do have a tendency to loosen apart. So if you want them to stay use some Loctite or some other locking product to keep them in place like they are here. And that's it. |
