Description
The Asimeto Ring Thread Gauge (NoGo) – Metric – Right Hand – 6g – M33 x 1 is a precision QC tool designed for engineers, machinists, and quality inspectors who need dependable verification of thread pitch diameter. Part of the 686 Series, this NoGo gauge confirms whether a fastener’s thread diameter exceeds tolerance, helping ensure only correctly sized fasteners are used in assemblies.
- Gauge designation: NoGo ring gauge for quick pass/fail assessment of metric threads
- Thread size: M33 x 1, right-hand thread
- Tolerance class: 6g, precision aligned with common metric standards
- Series: 686 Series, engineered for consistent, repeatable measurements
- Measurement focus: Specifically measures pitch diameter to verify tolerance compliance
- Material quality: Crafted with high-quality materials for durability and long-lasting performance
Using this gauge helps ensure that fasteners will thread properly and fit reliably in mechanical assemblies. The NoGo designation provides an objective indication: if a fastener cannot pass through the gauge, its pitch diameter is too large for acceptable use. Ideal for incoming inspection, in-process quality checks, and final assembly in automotive, aerospace, machine shops, and other precision manufacturing environments. The right-hand orientation and robust construction support accurate, repeatable checks across batches, reducing misfits and rework.
