Spi 34-462-2 Threaded Ring Gage M2.2x0.45 Class 6G No Go

Product Description

The SPI 34-462-2 is a single threaded ring gage configured for No Go inspection of M2.2 x 0.45 metric threads to Class 6G tolerance. Manufactured from Oil Hardened Non-Shrinking Steel (OHNS), this gage is designed for use in quality control and incoming inspection workflows where precise thread rejection is required. The No Go member verifies that an externally threaded workpiece does not exceed the maximum material condition, allowing inspectors to confidently reject out-of-tolerance parts. NPL Traceability Certification is included, supporting documented measurement assurance programs in regulated manufacturing environments.

This gage is suited for production floor and inspection lab use in industries where small-diameter metric threaded fasteners and components are manufactured or assembled. Class 6G specifies a standard tolerance class for external metric threads, making the 34-462-2 appropriate for general-purpose thread inspection on M2.2 x 0.45 workpieces. It is commonly used by quality technicians, machinists, and metrology personnel performing go/no-go verification to applicable thread standards.

Key Features

• No Go configuration for rejecting oversize M2.2 x 0.45 external threads at Class 6G tolerance
• Single ring design for dedicated No Go inspection duty
• Oil Hardened Non-Shrinking Steel (OHNS) construction for dimensional stability and wear resistance
• NPL Traceability Certification included for measurement assurance and audit compliance
• UNSPSC Code 41111619 for procurement classification

Compatibility

Designed for inspection of externally threaded workpieces with M2.2 x 0.45 metric thread form at Class 6G tolerance. Use in conjunction with a matching Go ring gage to complete a full go/no-go inspection set.

Installation Notes

Thread ring gages are used by quality technicians and machinists and require no permanent installation. Store gages in a clean, dry environment and apply a light coat of oil when not in use to prevent corrosion. Before use, verify the gage has been calibrated and that the traceability certification is current per your facility quality management requirements. Never force a ring gage onto a threaded workpiece, as this can damage the gage or produce a false reading.
