Vermont Gage 112106820 Class Zz Plus Plug Gage 6.82mm

Product Description

The VERMONT GAGE 112106820 is a Class ZZ Plus plug gage designed for precision bore and hole inspection in machine shops, quality labs, and manufacturing environments. It measures 6.82 mm in diameter with a tolerance of 0.00508 mm, making it suitable for go inspection applications where tight dimensional control is required. The gage body is manufactured from tool steel and features a 10 microfinish surface coating for consistent, repeatable contact with workpiece surfaces. Overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST standards, supporting documentation requirements for ISO and AS9100 quality systems.

This plug gage is used in go inspection routines to verify that a bored or drilled hole meets minimum size requirements. It is also used to set and verify micrometers, vernier calipers, bore gages, and other dimensional measuring devices. Typical users include machinists, quality control technicians, and metrology lab personnel working with metric-dimensioned parts. The 6.82 mm size suits applications in general machining, tooling, and component manufacturing where metric hole tolerances must be confirmed to ASME B89.1 standards.

Compatibility

Designed as an OEM-style go plug gage for use with standard gage handle sets and pin gage holders accepting 6.82 mm diameter gage pins. Compatible with go inspection routines for micrometers, vernier calipers, and other measuring devices as noted in the product specifications.

Installation Notes

Plug gages should be handled by metrology or quality control personnel following standard gage-handling practices. Always clean the gage and the workpiece bore with a lint-free cloth before use to prevent false readings from contamination or debris. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece surface. Store in a protective case away from temperature extremes to maintain dimensional stability and surface finish integrity.
