BALAX M4 x 0.7 6H thread plug gauge assembly is a go/no-go gauging tool for validating internal M4 x 0.7 threads. The GO size is 3.545 mm and the NOGO size is 3.663 mm, confirming the thread diameter limits defined by the 6H tolerance class. Use this assembly to verify that an M4 x 0.7 threaded part will assemble with standard fasteners, and to check thread consistency during manufacturing and inspection. This BALAX plug gauge assembly provides a precise, repeatable reference for critical thread-root dimension checks and helps ensure interchangeability of threaded components.
