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!
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.
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
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.
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
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.
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.
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!
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.
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.
