VCOIL Plug Gauge (D/E) - UNC (STI) - Heli Coil Gauge - Right Hand - 3B - 3/4 x 10

The VCOIL Plug Gauge (D/E), UNC (STI), Right Hand, 3B, 3/4 x 10 is a precision internal-thread gauge designed to verify threads quickly and reliably in manufacturing and quality control environments.

• Standard compliance: Manufactured and assessed to ANSI/ASME UNC thread system specifications for consistent, repeatable results.
• Go/No-Go thread plug design: Combines go and no-go checks in a single gauge to streamline inspection.
• Scrap identification: Scrap side is clearly marked with a red ring for easy identification during testing.
• Go-end operation: The go end should screw into the cut thread by hand using normal force; failure indicates the thread does not meet standards.
• No-Go-end limit: The scrap end should not be screwed more than two turns into the cut thread under normal force; exceeding this indicates nonconformance.
• Thread form and orientation: Right-hand UNC (STI) configuration with 3B internal thread class for reliable matching to mating parts.
• Size: 3/4 x 10, aligning with standard imperial thread measurements for common fastener applications.
• Durable, grip-friendly body: Knurled barrel provides secure handling during inspection and reduces slippage in busy work environments.
• Reference temperature: Parts and gauges are specified with a reference temperature of 20°C to ensure consistent measurements across environments.

By delivering clear go/no-go feedback with a tactile, easy-to-use design, this gauge helps you confirm thread quality, reduce scrap, and maintain steady production standards. Its built-in field practicality supports fast QC checks, while adherence to recognized ANSI/ASME guidelines gives you confidence in every measurement.
