VCOIL Plug Gauge (GO) - UN (STI) - Heli Coil Gauge - Right Hand - 2B - 1.3/4 x 8

The VCOIL Plug Gauge (GO) for UN (STI) Helicoil systems is a precision go gauge crafted to verify internal thread quality to ANSI/ASME standards. Designed for right-hand threads and sized 1.3/4 x 8, this 2B-class gauge supports reliable, repeatable inspections in quality control workflows.

• Go gauge for UN (STI) threads: intended to screw into the thread cut in a part by hand without excessive force, confirming conformance or flagging non-compliant workmanship.
• Right-hand orientation: specifically configured for standard right-handed UN/ STI threaded applications common in Helicoil installations.
• Size: 1.3/4 x 8, matching typical UN/ STI thread specifications used with Helicoil inserts.
• 2B tolerance/class: aligned with established thread gauge classification to ensure consistent measurements across parts.
• ANSI/ASME compliant: manufactured and assessed in accordance with relevant American standards for reliable results.
• Reference temperature: parts and gauges are specified at 20°C to maintain measurement consistency.
• Calibration options: factory calibration certificate available on request; calibration performed at an independent measurement laboratory to DIN, ISO, and ANSI standards, using IAC thread scanners for traceable results.

Using this Go gauge helps you confirm that the thread engagement meets specification before Helicoil installation, reducing scrap and rework. With a clear pass/fail standard and traceable calibration options, it supports rigorous quality control and consistent assembly performance in manufacturing and repair environments.
