Confirm Fastener Size and Thread Pitch to Prevent Damage During Assembly

We’ve all been there. A single missing bolt or nut is preventing forward movement on your build project, but that’s not going to stop you. Your coffee cans full of wayward nuts and bolts you’ve collected for years under your workbench are finally going to pay off. Thing is, once you’ve dumped that can out on the floor and sifted through the pile, how can you be sure the bolt that looks like it will fit actually will? Sure, you can take it over to your engine or whatever it is you’re building and try screwing it in and do that repeatedly until you find something that works. Or you might even grab your tap and die set and try to use that as a screw or bolt thread checker tool (news flash, not the best use of said tap and die set!). No, what you need is a proper thread pitch gauge tool like the ones you see mounted on the shelves in the fastener aisle at the hardware store but conveniently located right on your own workbench.

Our thread measuring tool is the perfect solution to your fastener verification needs. Machined from 6061 aluminum, this thread pitch gauge set is a stout piece at a 3/16-inch thick and weighing in at just over two pounds. Rigid, with no flexing and featuring rubber feet to prevent movement in use, this 17.5-inch long by 4.5-inch-wide thread gauge tool is ready at a moment’s notice to verify your SAE or Metric hardware to ensure you’re using the correct fastener for your project. Steel thread inserts are fitted to the thread check tool for verification of nuts and other internally threaded fasteners, while the aluminum thread gauge tool is machined and threaded directly for checking externally threaded bolts of all types, including fine and coarse thread SAE hardware. Eight of the most commonly used Metric and SAE drill bit size holes are machined directly into the screw checker, and you’ll also find 6-inch and 15cm rulers along the edges for use as a thread measuring tool for fastener lengths and other measurement needs. The black anodized finish with laser etched information provides an easy-to-read contrasting surface on the thread pitch gauge tool as well.
