Description
Asimeto Ring Thread Gauge (Go/NoGo) in imperial size is a precision external-thread gauge designed for machinists, inspectors, and quality-control teams who demand quick, reliable thread validation. This right-hand gauge delivers accurate depth and tolerance checks in a single, efficient pass, aligned with ASMEB1.20.1-2013 standards.
- Go/NoGo design: Distinct Go and NoGo segments provide immediate pass/fail feedback for each thread form, speeding setup and inspection.
- Imperial size: Calibrated for standard imperial external threads — 1-1/4 in diameter with 11.5 TPI, ensuring correct fit assessment on common fasteners.
- Right-hand orientation: Specifically configured for typical right-handed external threads found in most components and assemblies.
- 3-step L3 design: Three-step depth verification delivers precise measurement of thread depth and tolerance, reducing ambiguity during checks.
- ASMEB1.20.1-2013 compliant: Built to conform with a widely adopted standard for ring gauges, supporting consistent inspection practices.
- Durable construction: Robust metal construction designed for repeated use in busy workshops, delivering stable performance over time.
This gauge helps quality teams verify thread accuracy before parts enter critical assemblies, reducing rework and scrap and speeding up production lines. Ideal for machining shops, inspection labs, and manufacturing environments where reliable external thread validation is essential for fit, function, and long-term reliability.
