Description
Insize Thread Plug Gauge
The Insize Thread Plug Gauge is a precision inspection tool designed to verify internal Unified National Fine (UNF) threads for correct size, pitch, and tolerance. Using the GO / NO-GO gauging principle, it provides a fast and reliable method for confirming thread conformity in machining, maintenance, and quality control applications.
