Plain gauge manufacturer in Coimbatore: GO/NO-GO plug, ring, snap, and setting masters from 1 mm to 250 mm, in OHNS (W) or carbide, with certificates aligned to your tolerance band.
A plain gauge is a GO/NO-GO limit gauge for a cylindrical hole or shaft — plug, ring, or snap — that gives a pass/fail result without a measured reading. Shops use them for production acceptance and incoming inspection when a comparator would be slower than the line.
