Precisely verify external BSP and BSPP threads with confidence using the Asimeto Ring Gauge NOGO (NoGo) for 6G tolerance. Designed for machinists, inspectors, and plumbing/hydraulic technicians, this gauge delivers fast, reliable checks that keep fittings in spec and production moving.
- 6G tolerance class: Conforms to the strict 6G standard for accurate external thread verification on BSP/BSPP fittings.
- NoGo gauge: Specifically engineered to quickly identify out-of-tolerance threads, enabling clear pass/fail decisions.
- BSP and BSPP compatibility: Validates external threads for British Standard Pipe and British Standard Pipe Parallel connections.
- Right-hand threading: Optimized for right-handed BSP threads to ensure correct orientation during inspection.
- Threaded bore matched to size and pitch: Precise bore dimensions align with the target thread size and pitch for straightforward checks.
- Durable construction: Built from high-quality materials to resist wear, delivering long-lasting performance in busy workshops.
- Dimensions: 2 3/4 x 11 (as specified for this 690 Series gauge), engineered for reliable handling and consistent reference during inspection.
- Part of the 690 Series: Trusted lineage within Asimeto’s line of precision thread gauges for consistent results across tools.
This gauge is ideal for quality control stations, workshop teams, and maintenance technicians who routinely assemble BSP/BSPP connections. Use it to prevent cross-threading, ensure proper engagement, and reduce rework by quickly confirming that external threads conform to 6G specifications. For a complete inspection workflow, pair the NoGo gauge with a corresponding Go gauge to verify both the upper and lower limits of the thread fit, and keep the tool clean and calibrated for best results.
