GA-44C 55 degree Whitworth Screw Pitch Gage, 28 Blades, measures 4-62 threads per inch

This is the first thread gauge that also has the common bolt/stud sizes the thread pitch comes in...a very neat addition! The thumb nuts also make it easy to find the right thread pitch without breaking nails or having to use pliers to fan thru the blades. Aa excellent thread pitch gauge!

nice pitch gage

Same.

Nice gauge. Would have gave it five stars but the tension wheels are plastic. Good product for the price
