VCOIL Plug Gauge (D/E) - Metric (STI) - Heli Coil Gauge - Right Hand - 4H - M18 x 1.5 FMH FLH FHH S&E A&NF M&D Long shank for deep grooveThe VCOIL Plug Gauge (D E) is a metric, right hand Helicoil gauge that verifies M18 x 1. 5 inserts to ANSI ASME standards. Designed for precise quality control, it combines go and no go checks to confirm correct thread form at a reference temperature of 20C. Go No Go design: Combined go and no go ends test thread acceptance; the go end screws in by hand if the thread meets spec, while the no go end must not turn more than two turns if scrap. Thread
