Vermont Gage 112111900 Class Zz Plus Plug Gage 11.9mm

Product Description

The VERMONT GAGE 112111900 is a Class ZZ Plus plug gage designed for go inspection of bored, drilled, and reamed holes with a nominal diameter of 11.9 mm. Manufactured from tool steel, this gage holds a tolerance of 0.00508 mm and features a 10 microfinish surface for consistent, repeatable contact. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting the requirements of ASME B89.1. Machinists, quality technicians, and metrology professionals use this gage to verify that a feature meets its minimum allowable size before an assembly moves forward.

This plug gage is suited for dimensional inspection on the shop floor, at a receiving inspection station, or in a metrology lab. It is compatible with standard gage handle setups and is commonly used alongside set micrometers, verniers, and other precision measuring devices. With an overall length of 2.0 inches, the gage fits conventional double-end or single-end handle assemblies used in general manufacturing and toolroom environments.

Key Features

• Class ZZ Plus tolerance of 0.00508 mm for go-inspection applications
• 10 microfinish surface for precise, repeatable gage contact
• Tool steel construction for wear resistance and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standard
• Overall length of 2.0 inches for use with standard gage handles

Compatibility

Designed as an OEM-style go plug gage for use with standard gage handle assemblies in toolroom and shop-floor inspection applications requiring an 11.9 mm nominal diameter check.

Installation Notes

Plug gages are installed and used by machinists, quality technicians, and metrologists - no specialized certifications are required, but proper gage handling technique is essential to avoid wear. Before use, clean both the gage and the workpiece bore with a lint-free cloth to remove chips, coolant, and debris. Apply light gage oil if storing for extended periods to prevent corrosion. Never force a plug gage into a bore; if resistance is encountered on a go gage, the feature is likely out of tolerance.
