THREAD PITCH GAUGE W/W MM
A thread pitch gauge for checking both Whitworth and metric thread pitches.
This is a thread pitch gauge covering both Whitworth and metric threads. It's a shop tool, not a motorcycle part off the bike, and it's meant to help you identify what thread you're dealing with when you're sorting hardware or trying to match a bolt to a nut without guessing.

If you work on older British iron you know the parts bin ends up a mix of Whitworth, BSF, UNF, and metric fasteners over the years, and a gauge like this saves you from stripping something out by trial and error. Lay the leaves against the thread crest and it'll tell you the pitch.
We don't have much more detail on this one beyond what's listed, but it's a straightforward tool that earns its spot in a toolbox for anyone sorting through mixed vintage hardware.
