Description
Insize Thread Plug Gauge
The Insize Thread Plug Gauge is a precision inspection tool designed for checking internal metric threads against specified tolerance limits. It provides a fast and reliable GO/NO-GO method to confirm correct thread form, pitch diameter, and interchangeability in machining, manufacturing, and quality control applications.
During inspection, the GO end must screw fully into the threaded hole, while the NO-GO end must not enter beyond the allowable limit. This ensures threads are produced within ISO tolerance requirements and helps prevent oversize, undersize, or damaged tapped holes.
