VCOIL Plug Gauge (D/E) - UNF (STI) - Heli Coil Gauge - Right Hand - 2B - 1.1/4 x 12 G Wear-resistant carbide with durable W

Wear-resistant carbide with durable W coating: Built to resist wear

and improving overall thread-fitting reliability across parts and assemblies

delivering consistent surface quality on features that are hard to reach from the front

helping you achieve accurate parts pass after pass

5 micron run-out for exceptional concentricity: Achieves tighter tolerances and smoother finishes by minimizing tool deviation during rotation

VCOIL Plug Gauge (D/E) - UNF (STI) - Heli Coil Gauge - Right Hand - 2B - 1.1/4 x 12 G Wear-resistant carbide with durable WThe VCOIL Plug Gauge is a precision go no go thread gauge designed for UNF (STI) threads used with Heli Coil inserts. Its sized for right hand threads, 2B tolerance, and a 1 1 4 x 12 UNF specification, built to ANSI ASME standards for reliable thread verification. Thread standard: UNF (STI) thread system per ANSI ASME guidelines, ensuring consistent thread validation. Go No Go design: Combined go and no go plug gauge to confirm acceptable thread
