Screw Pitch Gauges

Produced from hardened and polished stainless steel, and is used for checking tool angles while machining threads in metal turning lathes. Whitworth, BSF, BA, Metric, American National and Acme thread angles are clearly etched on the plate for easy recognition.

Screw Pitch Gauges quickly determine the pitch of various external and internal threads. These gauges consist of a substantial steel case with a number of folding leaves at both ends, each leaf having teeth corresponding to a definite pitch.
