Threaded Ring Gage: 1-1/4-18 Thread, UNEF, Class 3A, No Go MPN:R1250183ANK

The threaded ring gage is an accurate measuring tool designed for inspecting externally threaded components using threaded ring gaging systems to ensure conformity with standards. With a 1-1/4-18 UNEF (Unified Extra Fine) thread, this plug style go gage fits the tapped hole rather than engaging threads, making it suitable for measuring various materials such as aluminum, brass, and steel in their thread form and alignment. Manufactured to ISO Class 3A, this ring gage meets high precision standards required in industries like aerospace, automotive, defense, medical, energy, and more. In use, it can be inserted into the hole until it contacts the bottom without going too far and then tightened until its head touches the mating surface while a no-go gage measures internal clearance on the exterior of the thread. Typical customers who would use this tool are quality control professionals, machinists, inspectors, engineers, mechanics seeking reliable solutions to inspect and detect whether parts meet specifications for precision in manufacturing processes.
