VCOIL Plug Gauge (D/E) - UNF (STI) - Heli Coil Gauge - Right Hand - 2B - No. 4 x 48 Insert reducing frequency of sharpenings andThe VCOIL Plug Gauge is a precision thread gauge designed for Helicoil insert testing, built to verify UNF (STI) right hand threads against ANSI ASME standards. It combines go and no go functionality in a single tool for quick, reliable pass fail checks. Thread system: UNF (STI) right hand threads aligned with ANSI ASME standards for accurate compatibility checks Go No Go design: Integrated go plug gauge and no go plug gauge to confirm both minimum
