Vermont Gage 112111020 Class Zz Plus Plug Gage 11.02mm

Product Description

The VERMONT GAGE 112111020 is a Class ZZ Plus cylindrical plug gage machined from tool steel and used to verify bore diameters to a high degree of accuracy. Nominal diameter is 11.02 mm with a tolerance of 0.00508 mm, and the working surface is finished to a 10 microfinish rating. The gage conforms to ASME B89.1 dimensional standards and ships with a Certificate of Accuracy that carries full NIST traceability. Overall length is 2.0000 inches. Machinists, quality technicians, and toolroom inspectors use this gage during incoming inspection, in-process checking, and final verification of machined bores.

This plug gage is suited for go-type inspection of precision holes in production and toolroom environments. It is appropriate for use alongside set micrometers, verniers, and other calibrated measuring devices where a physical reference standard is required. The Class ZZ Plus tolerance class addresses applications demanding tighter control than standard Class ZZ, making it a practical choice for close-tolerance work in manufacturing, aerospace, automotive, and general metalworking shops.

Key Features

• Nominal diameter of 11.02 mm with a 0.00508 mm tolerance for precise go inspection
• 10 microfinish surface on the gaging diameter reduces wear and improves measurement consistency
• Conforms to ASME B89.1 dimensional gage standards
• Includes a Certificate of Accuracy with NIST traceability for documented calibration records
• Tool steel construction for hardness and long service life in production environments
• Overall length of 2.0000 inches fits standard gage handle sets

Compatibility

Designed as an OEM-style replacement and direct-fit gage member for use with standard cylindrical plug gage handles sized to accept 11.02 mm diameter members; compatible with go inspection setups, set micrometers, verniers, and other calibrated measuring devices as noted in the product specifications.

Installation Notes

Plug gage members should be installed and handled by qualified metrology or toolroom personnel. Clean the gage shank and handle bore before assembly to prevent contamination that could affect accuracy. Never force a plug gage into a bore; if the member does not enter freely during a go check, the workpiece bore is undersize. Store the gage in a protective case away from moisture and temperature extremes to maintain calibration integrity.
