The Asimeto Ring Thread Gauge NoGo is a precision tool for technicians, inspectors, and quality teams working with metric threads. Designed for the 6g tolerance class, it delivers reliable pitch-diameter verification to ensure only correctly sized fasteners are used.
- Tolerance Class: 6g metric tolerance for accurate pitch-diameter measurement.
- Designation: NoGo to determine whether threads are too large or out of tolerance.
- Thread Size: M33 x 3 with right-hand orientation for standard metric threads.
- Orientation: Right-hand gauge configuration to match common threading conventions.
- Series & Construction: 686 Series crafted for precision and durability with high-quality materials.
- Intended Use: Ideal for quality control, production inspection, and maintenance where thread fit matters.
Using this NoGo gauge helps your team quickly validate thread compatibility: if a fastener cannot pass through the gauge, the pitch diameter exceeds the maximum limit and must be adjusted. The 686 Series construction provides consistent, repeatable measurements in busy workshop environments, supporting safer, more reliable connections and reducing rework due to undersized or oversized threads. Perfect for machinists and quality professionals who demand accurate metric threading checks in daily operations.
