Tri-Groove Security Nuts

“Trident” Tri Groove Security Nuts

Tri Groove security nuts are nuts that are installed with a very unconventional drive. These nuts have three slots in them, making them unique in shape and appearance. They have a cone shape, designed to be gripped only by the device intended to tighten and loosen them.

You can commonly find these in places where security or vandalism is a concern. To test these nuts we decided to install one ourselves and test a couple of different tools to see if we could remove them quickly.

First, we installed the nut using a tri-groove socket tool specially designed for this drive style. After install, we attempted to tamper with this fastener ourselves to determine what it would take to remove it.

We tried using an adjustable wrench. That didn’t work, the cone shape of the nut showed no gripping areas to lock the wrench into. We also tried pliers which had the same effect. Vice grips were our last attempt to break this nut loose with a conventional tool. However, the cone shape made it incredibly difficult to find a locking point. So we attempted to grab the lip and the base of the installation. The lip proved to be too small to get a good grip, leading us to our conclusion.

Conclusion

Having tested several different removal methods for removing this nut, we have determined that without either the proper tool or physically altering the shape of the nut (perhaps with a grinder) to provide a gripping point for more conventional tools, it is unlikely that this nut will be easily tampered with when installed correctly.

*Although these nuts are fairly secure there is still a chance that someone could have enough know-how or time to alter the shape of the nut or may have come across the proper tool to remove them.

How to Remove a Rivet

How to Remove a Rivet

remove a rivet

Rivets are very useful tools that are used  to quickly and efficiently connect two materials together. The problem is that they aren’t really designed to be removed.

We already did a post on how to remove a spinning rivet so if your rivets start spinning during this process please hop over to that post.(make this a link to the blog post once that post is live)

What You Will Need

drilling out a rivet

  • A Punch
  • Drill
  • Drill Bit



Remove a Rivet

Now that you have to tools that you need, get your safety gear on (gloves and glasses) and grab your punch.

Locate the center of the rivet with your punch and create an indent into the rivet on the flange(integral washer) side. This hole will provide a seat for the tip of your drill to sit in.

Now that you’ve made your hole and have your drill seated start slowly drilling into the rivet. You can use a drill bit that is the same size as you used on the install or smaller if you plan on reusing the hole. Make sure you apply steady pressure to the drill so that it stays in the seat you made for the bit.

You should be able to cut through the rivet very quickly. Once through back the drill out and whats left of the rivet should either fall or slide out with ease. Assuming you drilled with the right size your hole should still be the same size as it was before you installed the first one.

How To Make Your Own Pallet Key Holder

Making a Key Holder With Pallet Wood and Screws

Everyone has keys and our team at Albany County Fasteners is no different. We set out to create a place to hang our keys and put our mail. After reviewing many of the different styles available, we decided on a rustic wall key holder with a built in mail slot. Then we thought how can we make this simple and add our own spin to it.

The Tools

The Supplies




Step One: Getting the Wood and CuttingScrap Wood

After our last project, we decided to go ahead and remove wood from pallets so we had a supply to work with next time. So we went to our wood pile and chose 7 pieces of pallet wood at a minimum of 1 ft lengths.

We cut those boards into the following:

Two 3-1/2″ x 1 ft boards

One 3″ x 1 ft board

Two 3-1/2″ x 10″ boards

One 2″ x 10″ board

Two 2″ x 2-3/4″ Rectangles


Step Two: Basic Assembly

Now that we have all of our wood cut, we took the two 3-1/2″ x 1 ft boards and the 3″ x 1 ft board and placed them next to each other.

We then too one of the 3-1/2″ x 10″ boards and placed it across the top. This board will serve as a decorative piece for later. We can also use it to hide any uneven cuts in the wood with it.

Now we can flip this back over and place a 1-1/4″ long #6 Phillips Flat Head Wood Screw into each board to hold them to the 10″ board.Front Mail Catch

We also need to create the insert for the mail. Take the other 3-1/2″ x 10″ board and line it up on the edge of the 2″ x 10″ board. You are going to want to pre-drill holes into this as the wood is prone to splitting especially in such a tight area. We used a 3/16″ brad point drill bit for wood for this process. Then we installed two 1-1/4″ #6 Stainless Steel Slotted Oval Head Wood Screws into the holes.

Then we lined up the two 2″ x 2-3/4″ Rectangles on the two boards and repeated the drilling and screwing process further up. We now have the two pieces of our key rack ready to be assembled.

Assembly of these two parts is quite simple. After lining up the corners, we drilled 5 holes along the edge of the mail slot. Making a U shape to hold the slot to the backing.

Step Three: Key Ring Holders

Key Holders for key Rings out of fasteners

Now that we have our key holder together, we need something to hang our keys from. Using Screws all with different heads is a cheap and fun way to make easily identifiable key hooks. So we had everyone in the office pick a head and drive style, found them all in 1-1/4″ #12 Stainless Steel, and pre-drilled seven holes into the lower board using a 1/8″ bit.*

*Pro-Tip: To ensure you don’t drill too far into the wood, use blue painters tape on the drill bit to identify a stopping point.

 

 


Step 4: Adding Some Character

What key rack is complete without an easily identifiable saying? No key rack in our opinion. Thus we created a template on paper for and attached it to our top board using blue tape. We then drilled semi-equidistant holes through the paper and into the wood using the 3/16″ drive.

After removing our template, we took the 3/4″ #6 Stainless Steel wood screws and drove them into the pre-drilled holes.

Final Step: Hanging (your keys)

We are still deciding on the best place to hang this for us but in the mean time, we couldn’t resist hanging our keys on it to show you the finished product. We consider this build to be simple and it took us about 3 hours from start to finish. Leave and questions or comments below. We look forward to hearing about your exciting pallet key holder ideas!

How To Use A Screw Extractor

Removing Bolts and Screws With A Bolt ExtractorScrewing in a One Way Security Screw

To show you how to use a screw extractor we had to begin by getting a screw stuck into wood. We decided to demonstrate on a one way security screw, given that it is designed to not be removed after install. This drive style is designed to be driven in by a flat head, but it cannot be uninstalled with a flat head.

As a test, we were able to get vice grips around it but they would not hold when trying to loosen it. The screw is very firmly in the wood. So how do we extract it?

Enter the Screw Extractor

Drilling a Hole into the Screw

Bolt extractor bits are designed with reverse threading to dig into a screw and make it as easy as drilling until the extractor can grip the screw and break it loose from the wood, also known as “left hand drill bits.”

Our first step here is to punch a hole into the screw. This punch will allow the drill bit a place to sit and start drilling. There are two bits that come in a drill bit extractor set. There is a standard drill bit and a tapered bit with backwards threading. Place the smaller regular drill bit into the drill, seat the drill bit into the hole you’ve punched and begin to drill a small hole into the screw.

Once The Hole Is Drilled

Screw Extractor in action

Next, put the extractor bit into the drill. Make sure your drill is set to turn left when you start drilling. The bolt extractor bit has reverse threads. Insert the bit into the hole you just drilled and begin drilling to the left. Once the threads have enough grip on the screw they will stop drilling and break the screw loose from its hole.

Keep drilling and you will spin the screw all the way loose. Then take a pair of vice-grips or another pair of pliers and spin the screw off the drill bit. Congratulations! No longer will stripped screws stand in your way of completing a project.

             

How to Build a Threaded Rod Pallet Shelf

Building A Pallet Shelf Using Threaded RodCompleted Threaded Rod Pallet Shelf - Empty

Pallet shelving is incredibly popular for its rustic look and simple functionality. We’ve decided our office could use a display shelf and we had excess pallets lying around. Then we asked ourselves whats the point in building something if we can’t show it off and teach you how to make them for yourselves. (come back to this, needs a rewrite Mention Threaded Rod Pallet Shelf)

The Tools

The Supplies

Easily Remove Pallet BoardsStep One: Finding the Wood

After we put on our safety glasses and gloves, our first step when building this shelf was to locate pallets with wood of a similar size. We decided on 3 inch wide boards for the shelving. Once we identified the 18 pieces we wanted for our 2 foot lengths (shelves) we began removing them. Ten minutes and a broken hammer handle later, we decided we needed a better way to remove the boards. Using two pieces we were able to remove in this time, we used them to create better leverage and a pry bar. Moving back and forth across the board the nails easily came out and removing our boards became simple.

*Make sure to bring extra pallets if you are collecting them. Some boards are brittle and will snap or crack during this process.

After removing those 18 boards we then found 9 more boards that were slightly thicker (4 inches wide) for the supports. Using the same prying method we were able to remove them with ease. Since these boards were over two feet in length, we only needed 9 which we could then cut into 18 10-1/4″ support beams.

Step Two: Removing the Nails

This step was the most time-consuming by far. We thought about just hammering the nails flat against Remove Nails from pallets easilythe base but decided it wasn’t particularly safe and so we began bending them straight and removing them all with a hammer. The time this takes will vary. We had some boards only attached by 3 screws where others had 9 or more.

Pro Tips:

  1. Using the gaps inside a pallet to hammer the nails down through makes removing nails easy.
  2. If the length you want to use is shorter than the board, leave the screws in the end you will be cutting off and not using.

Step Three: Measure, Mark and CutMeasure and Mark wood for cutting

Once the wood is ready, take a moment and look at each piece. Check for splits in the wood and other chipping or excessive warping. This wood can still be used if the other side is clean. At this point sort your wood by width. You should have two stacks: one with 18 3″ wide pieces and one with 9 4″ wide pieces.

Take the first 3″ wide piece and measure two feet long. Mark this length and cut it with a chop saw. Measure again to ensure the length is correct at two feet. Then use this piece of wood to make the remaining 17 pieces. Repeat this process for the 4″ wide boards but with 10-1/4″ lengths.

*To save time when collecting the wood, we only gathered 9 pieces. Use the stencil to mark multiple cuts on the 4″ wood to make multiple lengths out of one board

Step Four: Assemble the ShelvesA Pallet Shelf Halfway built

Now that all of our wood is cut to length its time to begin assembling our shelves. Lay out three pieces of the 4″ wood and then three of the 3″ boards on top of it. It’s important to make sure you even out the spacing of the 4″ boards or it will look uneven when all of the shelves are stacked. Make sure your screws are screwed in off center. This way when you go to drill the holes for the threaded rod they will not be in your way. Starting with the outside boards, drill a single wood screw into each cross-section to hold the pieces together. Do the middle piece last as it will be easy to center once the edges are in place. Make 6 shelves by repeating this process

Pro Tips:

  1. If your boards are uneven, make sure you choose a side to be front and make that side as even as possible. No one will see the back and if it’s a little un-even that’s OK.
  2. We used blue tape before drilling into the wood to help prevent splitting and cracking around the screws.
  3. Do not over-tighten the screws, the ends will be held together with nuts. The over-tightening can cause splits in the wood.

Step Five: Drilling the holesDrilling Holes in Pallet Shelves

The next step was to measure the corner of the first shelf board, find the center and drill a hole with a 1/2″ spade bit. Do this for all four corners. We recommend drilling down into another piece of wood to avoid damaging the drill tip if you drill too far.

Once all four holes are drilled, make sure you have all 6 shelves with the front identified. Line up 1 or two of those shelves by the front making sure everything is flush, then take the first shelve (the one you already drilled through) and use it as a guide to drill even holes all the way down through your shelves. Once through, switch our the shelves with 1 to two more and continue until all six shelves have holes.

*Once completed line up all six and hold them up in the air. You should be able to see all the way through the hole.

Step Six: Putting it all together

Take four flange bolts and screw them onto the end of the threaded rod. Have two flipped upside down. These flanges will act as the feet and the first shelf will sit on the other two. Then begin Flange Nuts as feet for pallet shelfscrewing on four more in the same fashion from the top. One to push down against the first shelf and one to support the next shelf. Make sure you measure the gaps to know where to stop. Repeat this process until all of the shelves are sitting on four flange nuts and have four pressed down against the shelves as well.

Pro Tips:

  1. Our fastener Expert told us using coupling nuts and washers may be easier to install than using flange nuts.
  2. Don’t worry if the fixture seems unsteady. Once we tighten down the flange bolts it will be very strong
  3. The measuring at this stage is a loose indicator, we will fix that in the next step

Step Seven: Make the Shelves Equidistantmeasuring shelf height

Take a tape measure and from the bottom shelf, measure up to the next shelf. Decide on what distance you want for the shelves(we chose 13 inches). Measure each corner and adjust the bottom flange bolts as necessary until all shelves are even. Then take a level, place it on the bottom shelf and adjust the feet to even out the bottom shelf. From here you can work your way up the shelves and adjust the lower flange bolts accordingly to make each shelf level.

Step Eight: Tighten Up

At this point your threaded rod pallet shelf should still be a little wobbly. Take the 3/4″ wrench and tighten the top flange bolts down onto the shelves. Make these bolts very tight and then also tighten the bottom. Your shelf should stiffen up significantly at this point. From here on out there is only one more step.

Final Step: Decorate Your New Threaded Rod Pallet Shelf and LOVE IT!

Now that you have your completed and amazing looking shelf, its time to use it! We recommend keeping heavy weight on the bottom and lighter weight on top. Check out our decorations and tell us all about how your project turned out below!
