Screw pitch gauge - now double-sided - to measure both Whitworth (55-degree angle) and Metric (60-degree angle) threads. Includes templates for all common sizes. This is the best quality one that I've been able to find - not as good as a traditional Jones & Shipman, but still pretty decent.
The 8 t.p.i. version is currently out of stock. All others are available Thread Dial Indicators to fit Boxford as well as South Bend "9-inch" lathes - with either Imperial 8 t.p.i. or metric 3 mm pitch leadscrews.
