Roller Calliper Gauge

Screw thread roller calliper gauges are used to gauge external screw threads and can be manufactured to gauge all standard thread forms. Special thread forms, multi start threads and worm shafts can also be gauged with a screw thread roller calliper gauge. Setting plugs for calliper gauges are also available.
