I got one of these for free with a subscription a few years ago - I still have it and use it often. However, I separate my workshops - the wood workshop stays while the metal goes to the garage. This means I have to separate some of the hardware and tools I purchased for this upgraded metal shop model as I still get a lot of new and used equipment and need to identify it. It's also useful when you need to replace a broken screw or bolt. You can measure lengths in SAE and MM and navigate in thread pitches. As well as large and small nuts/washers. I love this one and it already sits in my tool box in the garage on a magnetic hook. Also from Revain I have a second sorting and counting bin that makes it easy to put loose items back in the bin. Together they make most hardware jobs a lot easier and I recommend both.
