The primary standard regulating metric thread gauges (rezbomers) is . This document specifies the technical requirements for sets of threaded templates used to determine the nominal pitch of a thread. Key Specifications of ГОСТ 519-77
: Standard metric sets typically cover pitches from 0.4 mm to 6.0 mm . Typical steps include 0.4, 0.5, 0.75, 1.0, 1.25, 1.5, 1.75, 2.0, and up to 6.0. Related Metric Thread Standards gost rezbomer metricheskij
: These tools, often called "thread pitch gauges" or "shagomers," are used to identify the pitch of metric threads and the number of threads per inch for imperial threads. Typical steps include 0
: Specifically designed for metric threads with a 60° profile angle . : A standard set consists of a series
: A standard set consists of a series of steel plates (approx. 1 mm thick) with serrated edges that match specific thread profiles.
While ГОСТ 519-77 covers the gauge itself, the dimensions they measure are governed by other standards:
