VCOIL Plug Gauge (D/E) - Metric (STI) - Heli Coil Gauge - Right Hand - 4H - M6 x 1

The VCOIL Plug Gauge (D/E) is a precision, right-hand metric Helicoil gauge designed for M6 x 1 threads. It is manufactured and assessed in accordance with ANSI/ASME thread system standards, and combines go and no-go checks in a single tool for reliable quality control.

• Go/No-Go plug gauge: A combined go end and no-go end to verify thread acceptance and rejection in one tool.
• Right-Hand configuration: Optimized for standard right-hand M6 x 1 threads used with Helicoil inserts.
• Metric (STI) specification: Designed to STI metric threading for compatibility with common components.
• 4H tolerance: Precisely manufactured to 4H class to align with metric thread tolerances.
• Red scrap ring: Scrap side is clearly marked with a red ring for easy identification during checks.
• 20°C reference temperature: Calibrated with a reference temperature of 20°C to ensure consistent results.
• ANSI/ASME compliant: Built and assessed to relevant ANSI standards for reliable performance in professional settings.

Using this gauge improves accuracy in thread validation, reduces the guesswork during Helicoil installations, and speeds up pass/fail decisions on the shop floor. The go end allows hand-screwing into the thread without excessive force to confirm proper engagement, while the no-go end prevents over-engagement, safeguarding component tolerance. Clear scrap-side marking and a stable 20°C reference further support repeatable, high-quality results in production and inspection environments.
