VCOIL Plug Gauge (D/E) - BSF (STI) - Heli Coil Gauge - Right Hand - Medium - 7/8 x 11

VCOIL’s right-hand BSF plug gauge is a precision go/no-go tool designed for Helicoil thread checks. Sized Medium at 7/8 x 11, it provides quick, hand-screw verification that aligns with ANSI/ASME thread standards.

• Go/No-Go design: A combined go end and no-go end verify thread suitability—go end threads into the cut by hand; no-go end should not advance more than two turns when within spec.
• Red scrap ring: Scrap side is clearly marked with a red ring for fast visual identification.
• Standards-compliant: Manufactured and inspected to ANSI/ASME thread system requirements, ensuring reliable tolerance checks.
• Right-hand BSF (STI) configuration: Specifically formed for right-hand British Standard Fine threads used in Helicoil installations.
• Size and scale: Medium size, 7/8" major diameter with 11 threads per inch.
• Reference temperature: Part and gauge measurements assume a reference temperature of 20°C to maintain consistency across checks.

Using this gauge helps you confirm proper thread engagement, reduce misfits, and streamline quality control during production or repair work. Its straightforward, hand-operated action makes it ideal for shop floors, inspection benches, and service environments where precise, repeatable thread verification matters.
