VCOIL Plug Gauge (GO) - Metric (STI) - Heli Coil Gauge - Right Hand - 4H - M40 x 3

The VCOIL Go plug gauge (Metric, STI) is a precision tool for verifying internal threads and helicoil repairs on M40 x 3 right‑hand threads. It’s designed for quality teams needing a reliable go gauge that screws in by hand to confirm thread suitability.

• Thread size and orientation: Metric M40 x 3, right‑hand Go gauge for internal thread verification.
• Standards compliance: Manufactured and assessed according to ANSI/ASME thread system standards with a 20°C reference temperature.
• Screw-in operation: The Go gauge must screw into the thread cut into a part by hand (without excessive force); if it cannot, the thread does not meet the required standards (scrap).
• Calibration options: Factory calibration certificate available on request; calibrated by an external measurement laboratory to DIN, ISO, and ANSI specifications using IAC thread scanners.
• Helicoil compatibility: Specifically referenced as a Helicoil gauge for ensuring helicoil‑repair threads meet spec.
• Size reference: 4H tolerance class indicated in the product details, suitable for precise fit with M40 x 3 threads.

Benefits: Use this Go gauge to quickly and decisively confirm thread integrity before assembly or repair, reducing scrap and rework. Its hand‑screwable design provides a straightforward go/no‑go check, while optional factory calibration certificates ensure traceability and compliance with DIN, ISO, and ANSI standards. The 20°C reference temperature helps maintain consistent measurements across production environments, supporting reliable quality control for helicoil installations.
