Description
Insize Thread Plug Gauge
The Insize Thread Plug Gauge is a precision inspection tool designed for verifying internal Unified National Fine (UNF) threads to ensure compliance with specified tolerances. Using the GO / NO-GO gauging principle, it provides a fast and reliable method for confirming correct thread form, pitch diameter, and interchangeability in machining, production, and quality control environments.

Manufactured from hardened and precision-ground gauge steel, Insize thread plug gauges provide excellent wear resistance and long-term dimensional stability. Clearly marked GO and NO-GO ends allow quick, repeatable inspection of internal threads, helping to prevent oversize or undersize tapped holes while maintaining consistent quality and compliance with international standards.
