One of the most critical tools for verifying these large external threads is the 3 1/8-8UN-2A Thread Ring Gage. But what makes this gage reliable? The answer lies in strict adherence to the ASME B1.2 standard and advanced metrology.

1.75-5 ACME-2G LH Left-Hand Thread Ring Gauge (ASME B1.5) was manufactured strictly in accordance with the ASME B1.5 standard.

4 1/2-6UN-2A Solid thread gage made in China, All parameters of thread ring gages are all in tolerance.

ASME B1.2, titled Gages and Gaging for Unified Inch Screw Threads, serves as the definitive standard governing the design, manufacture, and application of thread gages used to inspect Unified inch screw threads (UN and UNR thread forms). This standard provides essential specifications and dimensions for all thread gages and measuring equipment used in verifying the conformance of product threads to the design requirements established in ASME B1.1.
