Why it's on our shelf
We don't make every tool we sell. We hunt down the ones that measure true, last for years and make your shop work better, then put our name behind them.
If a tool can't hold a tolerance, it doesn't make the cut. No fiddling or re-calibrating on day one.
We pick materials and builds that can take drops, dust and years of real use.
Gear that stores well, mounts easily and stays within reach when you need it.
Questions about setup or fit? Our team builds in a shop too, and we'll help you get it right.

I am an organization freek and a horder of nuts, bolts and machine screws. When I saw this beauty I had to have one!! I have begun using it already. I'm thinking with two or three liters of Woodford Reserve I should be able to get through most of what I need to organize. Not positive, but I am willing to try. I really like that I could mount this puppy on the side of my main workbench for quick access. Great work Shop Nation. Come have some fun with me - and a good shot of Bourbon!
Loved having the magnets imbedded into the holder. Works great! Thanks Travis!
Overall, I like the quality of the materials. It looks and feels good and functions as expected. I like the extra mount so that I can put it on my wall. The magnets are strong. One accidentally fell out and got stuck to a nearby one and it was nearly impossible to pull apart. I'd recommend gluing it in.
This is an amazing quality product, very well made.
Quality product. Very happy with the purchase.
Built well and works great. Must have for sorting 100s of misc bolts.
Well built, going to be a nice addition next to my bolt storage.
Love the product. Nice to have on lazy, cold, Saturday sorting thru my pile of nuts and fasteners… finally sorting them all out. Feels good to be organized
Works great and is perfect size
I have this mounted out of the way, but it is so useful in determining thread count and bolt sizes. Having to go to a big box store to use their jig is a pain. Now I can size at home, order online, delivered to my shop and I don’t have to go down the mountain to the store! I love it.
Only had this for a couple weeks and have used it several times, great product!
This is a great product, I've been wanting one of these for a while. It's great that it has both metric and imperial thread sizes and is built much stronger than I thought it would be. It is a very nice addition to my shop
Great looking product. Could have used stronger magnets 🧲 but it hasn't fell yet. Must have for an operational repair shop.
LOVE IT!! this thing is solid and perfect!! will make a great addition to the shop!!
Work very well and look forward to us it in the feature.
Great Quality
Great quality at a great price!
Great product
It looks great and comes in handy.
High quality, well built, and so handy!
Feels like quality in your hands. The only drawback, which I hadn't even thought of until after I purchased, is that you can't use this to check threaded holes that are part of an assembly. As a for instance, I thought I was missing a screw to one of my shop tools, which I later found. I could not have used this tool to find the size of a replacement screw unless I already had a screw of that specific size on hand to test in the gauge. Other than that, this works great!
This is an extremely well built tool. The design and finish are top notch. Its usability is elegant; beats dragging out a ruler or calipers. And it helps create a smarter shopping list for the hardware store.
I have used the screw guide twice. It has help me purchase screws & nuts with the correct thread type and size
everything is as expected
,
Love how this mounts anywhere and can be removed from its magnetic perch. Very handy!
Exactly what my students need in the shop
Wanted one for years. Saves a significant amount of time searching for the correct nuts and bolts.
This is another very nice piece of equipment from Shop Nation. It's well designed and beautifully put together. If it wasn't so functional as a shop item...I might hang it on the wall in the living room (with my wife's permission of course). Well done and thanks for all your great products. Keep up the good work.
Overall, I feel this is great quality and should last a lifetime. It's threaded metal, not much to go wrong. I believe it's anodized and feels like it will not flake without being massively abused. The ONLY thing I can gripe about, and this is very minor and grasping at straws, is if you're expecting to use the rubber feet that come with this part, they're not held on very securely. A single screw is threaded through the rubber, which does not have any metal embedded within, thus when tightened pulls straight through. If you do not tighten the screws, the feet remain loose and may fall off. This is a moot point if you opt to mount this instead.
Well made and more robust than I expected. It seems accurate and I’ve used it several times so far to identify screw sizes and thread pitch. I’m very impressed.
Quality workmanship. Very handy tool that works well.
I thought this thing was too expensve for what it is. But I needed one, so I sprung for it. It is better than I had imagined! Very high quality aluminum with steel male threads. It's larger than I thought, too, which is good. Travis does a great job with his products.
the mounting clips did not support the weight when i placed it on the metal cabinet. I set the mount aside, removed rubber bumpers and installed 4 round magnets with a metric fastener. considering just using 2 of the magnets as all 4 make it very secured to the cabinet!
Great product, pieces are far enough apart to make it easy to use. Overall high quality materials. Very happy with purchase.
Perfect fit and finish. Using it currently to clean up my nuts and bolts drawers. Loving it for the help of organization and will be helpful going forward.
Awesome addition to the workshop. Used it the first day it arrived to figure out the size of some castors.
I used it the day it arrived, great to confirm size and threads so quickly!
The material and coating is excellent. So far all the threads match test fasteners so that is good. Ordering was quick, fast and easy. Can't beat any of that.
Great quality very well. Built should be very useful.
