VCOIL Plug Gauge (GO) - Metric (STI) - Heli Coil Gauge - Right Hand - 4H - M42 x 4.5

The VCOIL GO plug gauge is a metric, right-hand Helicoil gauge designed to verify that M42 x 4.5 threads meet established standards. It’s built for precision environments where a reliable hand-screwed go test quickly confirms thread acceptance.

• Gauge Type: GO plug gauge for metric (STI) threads used to validate the thread cut against standard specifications.
• Thread Size & Handedness: M42 x 4.5, right-hand thread, 4H tolerance tailored for Helicoil applications.
• Standards Compliance: Manufactured and assessed in accordance with ANSI standards defined by the ASME thread system.
• Go Test Method: Must screw into the thread cut into a part by hand, without using excessive force, to indicate acceptance.
• Calibration & Certification: Factory calibration certificate available on request; calibrated at an independent measurement laboratory to DIN, ISO, and ANSI specifications using IAC thread scanners; reference temperature 20°C.

Designed for dependable quality control, the VCOIL GO plug gauge provides a precise, traceable check of M42 x 4.5 right-hand threads. Use it to confirm that threads are cut to specification before assembly, helping reduce scrap and rework. When calibration is requested, you gain certification that aligns with recognized standards, offering confidence across manufacturing and inspection processes. The go-test workflow is straightforward and integrates smoothly into standard inspection routines, with a stable 20°C reference ensuring consistent results across parts and gauges.
