VCOIL Plug Gauge (D/E) - Metric (STI) - Heli Coil Gauge - Right Hand - 4H - M12 x 1 FLH repeatable checks of thread conformityVCOIL Plug Gauge (D E) is a precision metric go no go thread gauge designed for right hand M12 x 1 applications, built to STI metric standards with 4H tolerance. It provides quick, reliable verification of threaded holes and Helicoil insert compatibility in manufacturing and maintenance environments. Gauge type: Combined go no go thread plug gauge for fast pass fail inspection. Standards & range: Manufactured and assessed per ANSI ASME thread systems;
