Description
Insize Thread Plug Gauge
A GO/NO-GO thread plug gauge is a precision inspection instrument used to verify internal threads by checking that the pitch diameter is within the allowable tolerance range. The GO end must screw into or enter the threaded hole fully, while the NO-GO end must not pass beyond the permitted limit. This simple process confirms that the tapped thread size, pitch, and form comply with recognised standards, providing fast and reliable thread quality assurance for machining, production, and maintenance environments.
