Andrew I. ★★★★★

Pulled out a few bolts from an old project and this thing sorted the pitch and diameter in seconds. The built-in thread gauge actually cleaned up a rusty one too, which I wasn't expecting.

Adam ★★★★★

This little tool saved me a ton of guesswork when sorting through my mixed bin of bolts; the thread pitch gauge sits snugly against each size. I also love that the metal body helps straighten out the slightly bent ones before tossing them back in the drawer.

Victoria ★★★★★

The coarse and fine pitch guides are clearly marked, and it straightened a bent 10mm bolt from my lawnmower in seconds. At last I can identify mystery hardware without squinting at a ruler.
