Screw Chek'r® Inch Screw Identifier

Finally, a tool that actually works for sorting through my old hardware bin—the built-in thread cleaner is an added bonus. It handled a seized bolt from my lawnmower deck without any trouble.

This thing saved me from guessing which bolt went where during a messy garage cleanup. The thread-pitch gauge is dead simple to use, and I even straightened a couple of bent screws without any hassle.

I’ve got a box of mixed rusty screws that’s been sitting around forever, and this thing cleaned them up and gave me the diameter and pitch in seconds. The coarse and fine pitch readings are spot on, which saved me from guessing on a stubborn cabinet hinge.
