Industrial 5.3125-16 UNS-2B Thread Plug Gauge

Industrial 5.3125-16 UNS-2B Thread Plug Gauge by Ponam is a precision internal-thread inspection tool used to verify a 5.3125-16 UNS-2B threaded hole. This Go No Go gauge provides a two-sided check: the Go side confirms the thread can engage to the defined depth, while the No-Go side confirms that the thread will not accept beyond the prescribed limit. Sized specifically for the UNS-2B thread form, the gauge supports quality-control workflows in manufacturing and assembly by allowing quick, tactile validation of thread conformity before parts proceed to further processing. By using a dedicated plug gauge for this size and thread form, shops can reduce inspection ambiguity and maintain consistent dimensional accuracy across produced components. The designation 5.3125-16 UNS-2B identifies both the nominal thread size and the UNS subclass, helping ensure compatibility with parts machined to that specification and enabling traceable inspections in industrial settings. This one-part gauge is intended for calibration-based quality checks in industrial environments.
