Description
Insize Thread Plug Gauge
The INSIZE thread plug gauge is engineered specifically for accurate verification of internal metric threads using the GO/NO-GO principle. Manufactured in accordance with ISO 1502, the gauge provides a fast and dependable method to confirm that a threaded hole meets the required Class 6H tolerance. The GO end must engage fully with the component thread, while the NO-GO end must not enter beyond the permitted limit, ensuring correct assembly fit, interchangeability, and protection against oversize tapping in production environments.
