Aluminum fasteners are recommended in applications where light weight matters. Aluminum forms its own protective coating making it corrosion resistant. Aluminum fasteners are also incredibly easy to clean and require almost no maintenance. Due to this they are chosen for many budget builds. They are usually less expensive than stainless steel or brass and their lack of maintenence will make them a better choice than cheaper inferior materials over time.
However, aluminum is not always the best fit. It doesn't offer the same strength in shearing resistance, which is often the deciding factor in choosing a fastener for a project like airplanes and commuter trains. Aluminum fasteners are mostly limited to light duty uses.
Aluminum fasteners have other great attributes as well. The kinds of oxidization they are prone to will not leave marks on the metal. This is due to aluminums non-staining attributes. They have the best strength to weight ratio of all common metals. With the ability to be made stronger than mild steel, aluminum also boasts its weight by being only 1/3 that of mild steel. This can help to drive down transportation cost based on weight.
Aluminum is also incredibly resistant to other kinds of corrosion making it safe to use in environments where food or other chemicals are likely to be used to sterilize. It is also non-magnetic. We recommend only using aluminum with aluminum to help prevent galvanic corrosion.* Aluminum fasteners can also be painted for interior use to match whatever color is desired. It can also be used for many electrical applications due to its high levels of conductivity.
*Albany County Fasteners recommends only using aluminum with aluminum to deter the risk of galvanic corrosion. Read out blog post about galvanic corrosion to learn more about why you don't want to mix materials.

Bob: Welcome back to Albany County Fasteners - Fasteners 101. I'm Bob and I want to think wish you a Happy Thanksgiving. I hope you guys had a great one.
I've been off YouTube for a little while because we've been doing a lot of upgrades here in our warehouse. (We've) been changing out our racks you probably saw that video. We have a lot of new products coming and I'm gonna show you today a new product that we added about a week or two ago and that's our new aluminum line. So let's get started.
I have here a hex cap screw, aluminum, okay. I have a standard nut and a flat washer and in our new aluminum line, the bolts are grade 2024-T4. It's the most common aluminum grade; 1/3rd of the weight of mild steel. (Aluminum has the) Best strength to weight ratio of common materials.
So, I wanted to demonstrate it to you. I'm gonna put the washer on here and the nut and I want to demonstrate how much lighter aluminum is. I have the same size hex cap screws in other, different materials.
You can see it's a .0245 with the washer and with the nut. I'm going to take that off. .0245 is the number. This is zinc coated alloy - .0467 and that's just the hex cap screw. This (aluminum hex cap screw) is with the nut and the washer. That (zinc hex cap screw) is almost double the weight of an aluminum fastener.
The same thing, this is grade 8, .0466, about the same. .0469 That is 316 stainless. This is hot dip galvanized (zinc) .0496 versus .0246 and aluminum is corrosion-resistant. So it's another option, in lieu of, using stainless steel. (Plain steel) 0.470 and silicon bronze is .0515, the heaviest - silicon bronze.
So, this is a new line on our website that you could find there. You're gonna find it expanding throughout the year. We're gonna be bringing in sheet metal screws and machine screws. Right now, you're gonna find the washers and the nuts and the hex cap screws. And we're gonna expand that line along with threaded rod and probably a few other items in the aluminum line.
It's an awesome product and there are so many different applications for this product. Thanks for watching!
