Vermont Gage 112107560 Class Zz Plus Plug Gage 7.56 Mm

Product Description

The VERMONT GAGE 112107560 is a Class ZZ Plus plug gage machined from tool steel and finished to a 10 microfinish surface. It is designed to perform go inspection on machined bores and holes with a nominal diameter of 7.56 mm, holding a tolerance of 0.00508 mm. The gage ships with a Certificate of Accuracy traceable to NIST, confirming dimensional compliance to ASME B89.1. Machinists, quality technicians, and metrologists use this style of gage to verify bore dimensions during in-process and final inspection routines.

This plug gage is suited for shop-floor and lab inspection environments where bore diameter verification is required. Typical applications include go inspection of drilled, reamed, or bored holes at the 7.56 mm nominal size. It is also used alongside set micrometers, verniers, and other comparative measuring devices to establish reference points or confirm calibration. The gage is appropriate for both production-line inspection and low-volume precision work where NIST-traceable documentation is required.

Key Features

• Class ZZ Plus tolerance of 0.00508 mm for precise go inspection
• Tool steel construction for hardness and wear resistance
• 10 microfinish surface for consistent gage-to-bore contact
• Meets ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability
• Overall length of 2.0000 inches for standard handle compatibility

Compatibility

Designed for go inspection use with set micrometers, verniers, and other measuring devices requiring a 7.56 mm nominal diameter reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and metrologists; no power source or trade license is required. Clean the bore and gage surfaces before use to prevent debris from affecting readings or causing surface wear. Store the gage in its protective case when not in use to preserve the finished surface and maintain dimensional accuracy. Follow your facility calibration schedule and ASME B89.1 handling guidelines to ensure ongoing measurement integrity.
