Description
The Asimeto Ring Thread Gauge (NoGo) is a precision metric ring gauge designed for metric coarse 6g threads. It’s built for quality-focused shops and inspection teams that need fast, reliable checks on M45 x 4.5 right-hand threads.
- Series: 684 Series, metric coarse 6g thread gauge designed to fit tight tolerances
- Thread compatibility: Right-hand M45 x 4.5 thread specification for accurate assessment
- NoGo function: Checks the minimum material condition, ensuring the part size remains within the lower limit of the allowable range
- Calibration: Precisely calibrated to confirm the thread is within its defined tolerance band
- Construction: Metal ring with a knurled outer edge for secure grip and durable hand-use
- Usage: Ideal for fast go/no-go inspection in manufacturing, quality control, and assembly workflows
