Thredco 3/8-24 UNF-2B Thread Plug Gage

Description:

The Thredco 3/8-24 UNF-2B Thread Plug Gage is used in precision dimensional inspection to verify the accuracy and tolerance of 3/8-24 UNF Class 2B internal threads. Commonly installed in CNC machining centers, machine shops, aerospace manufacturing, automotive production, metal fabrication facilities, and quality control laboratories for inspection of tapped holes and threaded components. Quality inspectors, machinists, and maintenance technicians use this thread plug gage for in-process inspection, final quality verification, calibration, and replacement of worn thread inspection gauges.

Applications:

The Thredco 3/8-24 UNF-2B thread plug gage is designed to verify that internally threaded components conform to Unified National Fine (UNF) Class 2B dimensional specifications using GO/NO-GO inspection methods. It is widely used in precision machining, CNC manufacturing, tool and die production, aerospace, automotive manufacturing, industrial maintenance, and quality assurance departments where accurate internal thread inspection is essential for part interchangeability and compliance with ANSI B1.2 standards.
