The VCOIL Plug Gauge (D/E) is a precision go/no-go thread gauge designed for UNC (STI) Helicoil installations. Right-hand, 2B class, No. 6 x 32, this gauge verifies that threads meet ANSI/ASME standards with reliable, hands-on validation.
- Standards compliance: Manufactured and assessed to ANSI/ASME thread systems, ensuring consistent tolerances across parts.
- Go/No-Go thread limit gauge: Combines go and no-go ends in one tool to efficiently confirm thread quality against the standard.
- Go end operation: The go end must screw into the thread cut into a part by hand, without excessive force.
- No-Go (scrap) end criterion: The no-go side must not be able to be screwed more than two turns into the cut thread.
- Scrap side marking: The scrap side is clearly identified with a red ring for quick visual checks.
- Size and configuration: Right-hand, 2B class, No. 6 x 32 UNC (STI) Helicoil gauge designed for UNC thread checks.
- Temperature reference: Reference temperature for parts and gauges is 20°C to ensure consistent measurements.
The VCOIL Plug Gauge accelerates quality control by delivering precise go/no-go validation in a single, rugged tool. Its clear scrap marking and manual go-end check provide fast, reliable verification of thread integrity, helping reduce rejects and maintain consistent readings across shifts. Designed for UNC (STI) Helicoil applications, this gauge supports accurate testing of threaded holes and fastener fits in manufacturing environments, with a stable 20°C reference to ensure dependable results.
