VCOIL Plug Gauge (D/E) - Metric (STI) - Heli Coil Gauge - Right Hand - 4H - M14 x 1

Precision go/no-go thread gauge designed for Helicoil inserts in Metric M14 x 1 right-handed threads. Built to ANSI/ASME standards, it provides quick, reliable checks during installation and quality control.

• Go/No-Go design: Combines a go plug end that must screw into the thread by hand (without excessive force) with a scrap end that should not rotate more than two turns, ensuring the thread meets specification.
• Metric (STI) M14 x 1, right-hand, 4H: Specifically calibrated for the M14 x 1 right-handed thread with 4H tolerance class to align with standard Helicoil repairs.
• Red-scrap ring: Scrap side is clearly marked with a red ring for fast identification during inspections.
• ANSI/ASME compliant: Manufactured and assessed according to the relevant ANSI/ASME thread system for consistent results.
• 20°C reference calibration: Calibrated with a reference temperature of 20°C to support stable measurements in typical workshop environments.
• Ergonomic knurled body: Knurled surface provides secure handling and precise alignment during go/no-go checks.
• Right-hand orientation: Designed specifically for right-handed threads to match standard Helicoil installations.

The VCOIL Plug Gauge helps ensure Helicoil repairs and thread engagements meet exact specifications. The go end confirms proper insertion by hand, while the scrap end guards against overcutting, enabling reliable pass/fail decisions. With a clear red scrap-ring and a 20°C calibration reference, you’ll achieve repeatable results, reduce rework, and speed up quality checks on the shop floor.
