Vermont Gage 111302950 Class Zz Plus Plug Gage 0.0295 in

Product Description

The VERMONT GAGE 111302950 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small-diameter bores and holes. It measures a nominal diameter of 0.0295 inches with a tolerance of 0.0002 inches and features a 10 microfinish surface, making it suitable for Go inspection applications where accurate hole sizing is critical. Constructed from tool steel, this plug gage is built to withstand repeated use in production and inspection environments. Each unit ships with a Certificate of Accuracy with NIST Traceability, confirming conformance to ASME B89.1 standards. Licensed machinists, quality control technicians, and metrology professionals are the primary users.

This plug gage is used in precision measurement and inspection settings, including machine shops, tool rooms, and quality assurance labs. It is suited for Go inspection routines and for setting and verifying micrometers, verniers, and other measuring devices. The 0.0295-inch diameter addresses small-bore applications common in tight-tolerance manufacturing. Its compact overall length of 2.0 inches makes it easy to handle during bench inspection or inline production checks.

Key Features

• 10 microfinish surface for consistent, repeatable gage contact
• Tool steel construction for durability and dimensional stability
• Conforms to ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST Traceability
• Compact 2.0-inch overall length for easy bench or inline use

Compatibility

Designed as an OEM-style Class ZZ Plus plug gage for use with Go inspection setups and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring a 0.0295-inch diameter reference.

Installation Notes

Plug gages of this type are handled and used by quality control technicians and metrology professionals in inspection environments. Store the gage in its protective case when not in use to prevent damage to the precision-ground surface. Clean contact surfaces before each use to avoid measurement errors caused by debris or contamination. Handle with care to prevent dropping, as impact can alter the calibrated diameter and render the gage out of tolerance.
