VCOIL Plug Gauge (NoGo) - UN (STI) - Heli Coil Gauge - Right Hand - 2B - 1.5/8 x 8

VCOIL Plug Gauge (NoGo) for UN (STI) Helicoil threads is a compact Go/No-Go thread gauge designed for precise verification of right-hand, 2B-sized UN/Helicoil cuts. Built to ANSI/ASME standards, it delivers quick, reliable checks in busy production and QC environments.

• Go/No-Go plug gauge: Combines a go end and a no-go end in one tool, enabling fast, definitive thread validation for UN (STI) Helicoil applications.
• ANSI/ASME compliance: Manufactured and assessed to the relevant ANSI standards and ASME thread system, ensuring compatibility with standard thread cuts.
• Scrap-side red ring: Scrap side is clearly marked with a red ring for immediate visual differentiation during inspection.
• Right-hand configuration: Specifically designed for right-hand threads to match common Helicoil installations.
• Size and thread spec: Includes 2B size and 1.5/8 x 8 thread specification to align with typical Helicoil insert requirements.
• Temperature reference: Reference temperature of 20°C is used for parts and gauges to ensure consistent measurements.

Benefits: This gauge streamlines quality control by confirming that a hole or insert meets exact thread specifications with a simple hand-fit test. The Go end must thread into the cut portion by hand without excessive force, while the No-Go end must not thread more than two turns, helping you quickly identify scrap conditions. The red scrap indicator and a clearly defined 20°C reference support accurate, repeatable checks, reducing misreads and rework while maintaining tight tolerances on Helicoil installations.
