The Asimeto Ring Thread Gauge NoGo for Metric 6g threads is a precision inspection tool designed for machinists and quality-control professionals. Specifically calibrated for M2.5 x 0.45 right-hand threads, it verifies that the thread is within tolerance and aligns with the lower limit on the size.
- Gauge Series: 684 Series, engineered for metric coarse 6g threads.
- Thread specification: Right-hand metric coarse thread, M2.5 x 0.45 (6g).
- Gauge type: NoGo ring gauge that checks the minimum material condition to ensure the part stays within the lower size limit.
- Calibration: Precisely calibrated to confirm the thread is within the defined tolerance range.
- Intended use: Ideal for go/no-go inspections to ensure threaded parts do not exceed the maximum allowable size.
Using this NoGo gauge delivers fast, unambiguous pass/fail results during quality checks, helping reduce rework and scrap from undersized or out-of-tolerance threads. Its consistent reference improves repeatability across production batches, enabling traceable, reliable quality control. Designed for the precise needs of small-diameter metric threads, it is a valuable tool in precision manufacturing, assembly, and inspection workflows where accurate thread size verification is essential.
