Vermont Gage 112111100 Class Zz Plus Plug Gage 11.1mm

Product Description

The VERMONT GAGE 112111100 is a Class ZZ Plus plug gage manufactured from tool steel for dimensional go inspection of bored, drilled, and reamed holes. It measures 11.10 mm in diameter with a tolerance of 0.00508 mm (0.005 mm) and features a 10 microfinish surface on the gaging member. The overall length is 2.0000 inches. Every unit ships with a Certificate of Accuracy traceable to NIST, confirming compliance with ASME B89.1 standards. Machinists, quality technicians, and tool and die professionals use this gage to verify hole diameters in production and inspection environments.

This plug gage is suited for go inspection work on 11.10 mm diameter features in both job-shop and production-floor settings. Typical applications include verifying bored or reamed holes before assembly, setting micrometers, and calibrating verniers and other measuring devices. The Class ZZ Plus designation indicates a tighter tolerance grade than standard Class ZZ, making it appropriate where closer process control is required. It is used by machinists, quality engineers, and metrology lab personnel across light manufacturing, precision machining, and inspection operations.

Key Features

• 10 microfinish surface on the gaging member for accurate, repeatable contact
• Tool steel construction provides wear resistance in production inspection use
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 dimensional gage standards
• Compact 2.0000-inch overall length suits bench and in-process inspection

Compatibility

Designed as an OEM-style go plug gage for use with standard gage handle sets and suitable for setting micrometers, verniers, and other measuring devices requiring an 11.10 mm reference standard.

Installation Notes

Plug gages of this type are handled by quality technicians and machinists trained in dimensional metrology. Clean the gage and the workpiece bore before use to prevent debris from affecting the reading or damaging the gage surface. Never force the gage into a hole; go gages should enter under the weight of the gage or with light hand pressure only. Store in a protective case away from heat sources and corrosive environments to preserve the calibrated surface finish and dimensional integrity.
