Description
A precision go/no-go thread gauge for helicoil and BSP threaded holes, designed for Right Hand 3/8 x 19 applications. Engineered for quick, repeatable quality checks in machining and repair environments.
- Go/No-Go design: Combines go and no-go ends to verify both the entry and the limit of the thread to the required standard.
- Scrap-side marking: Scrap side is clearly identified with a red ring for fast visual orientation.
- ANSI/ASME standard compliance: Manufactured and assessed in accordance with relevant ANSI/ASME thread standards.
- Reference temperature: Parts and gauges specified to 20°C for accurate, repeatable measurements.
- Configuration: Right Hand orientation with BSP (STI) thread specification for the intended application.
- Size: 3/8 x 19, suitable for the specified helix coil / bolt-hole applications.
- Application: Designed for helicoil gauges and related threaded insert verification to ensure proper fit and performance.
This gauge supports reliable thread verification by confirming that the go end threads in by hand (without excessive force) and the no-go end cannot be advanced more than two turns, helping to prevent scrap and ensure consistent quality across parts and assemblies.
