Description
The VCOIL Plug Gauge (D/E) for UNC (STI) Helicoil gauges is a precision go/no-go thread limit gauge designed to verify right-hand UNC threads to ANSI/ASME standards. This 1 x 8, 2B class instrument combines a go plug end and a no-go end in a single gauge, with a red ring marking the scrap side for quick rejection decisions.
- Thread system: UNC (STI) - (D/E) Helicoil gauge
- Direction: Right Hand
- Class: 2B
- Size/Format: 1 x 8
- Gauge Type: Go/No-Go thread plug gauge
- Scrap indicator: Scrap side marked with a red ring
- Standards: ANSI/ASME thread system compliance
- Temperature reference: Parts and gauges reference temperature 20°C
Using this gauge provides quick, repeatable validation of thread quality in manufacturing and repair workflows. The go end ensures the thread can be mated by hand without excessive force, while the no-go end confirms the thread does not exceed the allowable depth, helping prevent mismatches and costly rework. The red scrap indicator speeds acceptance decisions, and the ANSI/ASME compliance ensures consistent measurements across tools and parts. Calibrated for a 20°C reference temperature, it supports reliable quality control for Helicoil UNC (STI) applications.
