VCOIL Plug Gauge (GO) - UN (STI) - Heli Coil Gauge - Right Hand - 2B - 1.7/8 x 8

The VCOIL Plug Gauge (GO) for UN (STI) is a right-hand Helicoil go gauge designed to verify thread cuts against ANSI/ASME standards. With a 2B tolerance and a 1.7/8 x 8 size, it provides quick, reliable go/no-go checks in helicoil applications.

• Go gauge type: Verifies that the thread cut will accept the gauge when screwed in by hand (no excessive force) to confirm conformity to spec.
• Thread system: UN (STI) thread standard compatibility for accurate sizing and replacement planning.
• Orientation: Right-hand gauge designed for common right-hand thread installations.
• Tolerance class: 2B, ensuring alignment with formal tolerance expectations for helicoil-compatible threads.
• Size / dimension: 1.7/8 x 8, precise catering to the specified UN/STI application.
• Calibration options: Factory calibration certificate available on request; calibrated by an independent measurement lab to DIN, ISO, and ANSI standards using IAC thread scanners.
• Standards compliance: Manufactured and assessed in accordance with relevant ANSI/ASME thread system standards for reliable performance.
• Temperature reference: Reference temperature of 20°C for parts and gauges to ensure consistent measurements.

Benefits: Using this gauge delivers confident, traceable acceptance testing for threaded holes and helicoil inserts. It helps reduce scrap by confirming that thread cuts meet required standards, supports quality audits with a requestable calibration certificate, and provides a straightforward go/no-go check that technicians can perform by hand, ensuring consistent results across production and quality control environments.
