Description
The VCOIL Plug Gauge is a right‑hand UNC (STI) Helicoil thread gauge designed for precise go/no‑go checks on No. 2 x 56 threads. Manufactured and assessed to ANSI/ASME thread standards, it provides reliable performance for quality assurance and assembly tasks.
- Go/No-Go design: Combines a go plug gauge and a no‑go plug gauge in one instrument to verify both acceptance and rejection criteria with a single check.
- Scrap identification: The scrap side is clearly marked with a red ring to indicate out‑of‑tolerance condition.
- Thread system: UNC (STI) thread form aligned with ANSI/ASME specifications for Helicoil inserts.
- Size and tolerance: No. 2 x 56, with 2B tolerance, in a right‑hand orientation.
- Temperature reference: Reference temperature for parts and gauges is 20°C to ensure consistent measurements.
Designed for reliability in production and inspection environments, this gauge helps ensure threads meet exacting standards. The go end should screw into the workpiece thread by hand without excessive force, while the scrap end must not thread in more than two turns, safeguarding against undersized or damaged threads. Clear red scrap marking and ANSI/ASME conformity support precise, repeatable results across operators and shifts.
