Vermont Gage 112310850 Class Zz Plus Plug Gage 10.85mm

Product Description

The VERMONT GAGE 112310850 is a Class ZZ Plus cylindrical plug gage machined from tool steel for dimensional go inspection applications. Measuring 10.85 mm in diameter with a tolerance of 0.00508 mm, this gage delivers the precision required for verifying bore and hole dimensions in production and quality-control environments. A 10 microfinish surface treatment on the gaging surface minimizes wear and ensures repeatable contact. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and metrology lab personnel rely on this class of gage for high-frequency go inspection routines.

This plug gage is suited for go inspection of machined bores, drilled holes, and reamed features requiring tight dimensional verification at the 10.85 mm nominal diameter. It is also compatible with setting and verifying micrometers, verniers, and other comparative measuring devices. The overall length of 2.0000 inches makes it practical for use with standard gage handles in both shop-floor and lab settings. Typical users include machinists, QC inspectors, and tool room technicians working to ASME or ISO dimensional tolerancing requirements.

Key Features

• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 gage standards
• Overall length of 2.0000 inches fits standard gage handles

Compatibility

Designed for go inspection of 10.85 mm diameter bores and holes; also used to set and verify micrometers, verniers, and other comparative measuring devices per the manufacturer application data.

Installation Notes

Handle plug gages with clean, dry hands or lint-free gloves to prevent corrosion and measurement error from skin oils. Store the gage in its protective case when not in use and allow it to reach ambient temperature before use to avoid thermal expansion error. Do not force the gage into a bore; go members should pass under the force of gravity or light hand pressure only. Periodic cleaning and re-certification per ASME B89.1 intervals is recommended to maintain accuracy.
