Vermont Gage 111117900 Class Zz Plus Plug Gage 0.179 in

Product Description

The VERMONT GAGE 111117900 is a Class ZZ Plus plug gage designed for precise dimensional inspection of bored holes, drilled holes, and other circular features. This gage measures a nominal diameter of 0.179 inches with a tolerance of 0.0002 inches, making it suitable for high-accuracy go inspection work. Manufactured from tool steel and finished to a 10 microfinish surface quality, it delivers consistent, repeatable measurements across production and quality control environments. Each unit ships with a Certificate of Accuracy backed by NIST traceability, meeting ASME B89.1 standards. Machinists, quality technicians, and tool room professionals rely on this type of gage for verifying that workpieces fall within specified dimensional limits.

This plug gage is used in go inspection applications to confirm that a hole or bore accepts a part of the specified minimum size. It is also compatible with calibration and verification setups involving set micrometers, verniers, and other precision measuring devices. Typical environments include manufacturing facilities, machine shops, tool rooms, and quality inspection labs where tight dimensional control is required. Its compact 2.0-inch overall length makes it easy to handle in bench or floor inspection scenarios.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no permanent installation is required. Keep gage surfaces clean and lightly oiled when not in use to prevent corrosion of the tool steel. Always handle with clean, dry hands or cotton gloves to avoid transferring oils or contaminants that could affect measurement accuracy. Store in a protective case away from impact, extreme temperature changes, and other gaging tools to preserve surface finish and calibration integrity.
