Description
The VCOIL Plug Gauge (D/E) is a precision metric thread gauge designed for Helicoil inserts. It delivers reliable go/no-go verification for M11 x 1.25 threads, calibrated to ANSI/ASME standards for consistent, repeatable results.
- Go/No-Go Thread Plug Gauge: Combines the go and no-go ends to verify thread quality against defined limits per ANSI/ASME.
- Red Ring Scrap End: Scrap side is clearly marked with a red ring for quick identification during inspections.
- Right-Hand Metric Thread: Configured for standard right-hand threads in metric sizes, specifically M11 x 1.25.
- 4H Tolerance Class: Precision tolerance class to suit Helicoil insert standards.
- Standard Reference Temperature: Uses a 20°C reference temperature for consistent part and gauge measurements.
- Quality Compliance: Manufactured and assessed to ANSI/ASME thread system requirements for reliability on the shop floor.
When you test threads with this gauge, you ensure that each Helicoil insert will thread in smoothly and hold to spec, reducing the risk of undersized or oversize threads that can cause failures or costly retries. The hand-screw test on the go end makes quick checks fast on the bench or in the shop, while the no-go end helps prevent over-tapping. The red scrap end provides an unmistakable indicator for pass/fail outcomes, supporting quick quality decisions and consistent assembly in production environments.
