The Asimeto Ring Thread Gauge (GO) from the 683 Series is a precision GO gauge engineered for metric coarse 6g threads, specifically in right-hand M18 x 2.5 size. Built for quality control and manufacturing environments, it delivers quick, reliable size verification to keep production moving smoothly.
- Series: 683 Series, calibrated for metric coarse 6g threads.
- Thread compatibility: Metric coarse 6g, M18 x 2.5, right-hand threads.
- Gauge function: GO gauge that checks the maximum material condition (upper size limit) of the part.
- Calibration: Precisely calibrated to ensure the thread is within tolerance.
- Applications: Ideal for quality control, inspection, and manufacturing environments requiring precise measurements.
Using this GO ring gauge helps inspectors quickly confirm that threaded components meet the upper-size limit, reducing the risk of oversized parts entering production or downstream processes. The result is tighter process control, fewer rework cycles, and more consistent part acceptance during routine QA or incoming inspections.
