Thread Ring Gauge INSIZE M22×1 6G, master screw pitch gauge (model 4129-22P)

INSIZE thread ring gauge M22×1 6G (model 4129-22P) is a precision master screw-type go/no-go ring gauge designed for inspection of external metric threads with nominal diameter 22 mm and pitch 1 mm. The gauge provides a Go-side and a No-Go side to verify dimensional conformity and basic thread form according to the 6G tolerance class. It is intended for use in quality control, incoming inspection, production monitoring and maintenance where reliable, repeatable verification of external threads is required.

Advantages

The INSIZE M22×1 6G ring gauge offers accurate pass/fail verification through a hardened, ground measuring surface that resists wear. As a master screw-type gauge it ensures consistent engagement with external threads and distinguishes acceptable parts from those outside tolerance. Its compact, single-piece construction makes it easy to handle and store, while the two-sided Go/No-Go design speeds up inspection and reduces subjective judgment during checks.

Suitable for

• Quality control of turned, rolled or ground external M22×1 threads
• Production inspection and in-process checks on batch manufacturing
• Incoming inspection of threaded components from suppliers
• Maintenance and quick field verification of threaded parts

Key specifications

• Thread form: metric ISO external thread
• Nominal size: 22 mm diameter
• Pitch: 1.0 mm
• Tolerance class: 6G acceptance class for external threads
• Gauge type: master screw-type, Go/No-Go ring gauge
• Construction: hardened and ground working surfaces for wear resistance
• Typical use environment: workshop, inspection bench, on-site maintenance

How to use

To check an external M22×1 thread, first ensure the gauge is clean and free of debris. Place the Go side onto the threaded part and rotate or push gently; a correct part should fully engage the Go side without excessive force. Next, test the No-Go side; it should not fully engage if the thread is within tolerance. If the No-Go side enters, the part is rejected. Use consistent hand technique and inspect multiple samples when monitoring a batch to confirm process stability.

Usage recommendations

Store the gauge in a dry, protected case to prevent damage to the measuring surfaces. Clean threads on both the gauge and the part before inspection. Avoid excessive force when engaging the gauge to prevent wear or damage. Periodically check gauge condition and calibration against a higher-order standard or replace if wear affects fit. Use appropriate personal protection when performing inspections in production environments.
