Vermont Gage 111167000 Class Zz Plus Plug Gage

Product Description

The VERMONT GAGE 111167000 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bored holes, drilled passages, and machined features. Built from tool steel, this fixed-limit gage checks whether a feature falls within acceptable dimensional tolerance using a go-inspection method. The measuring diameter is 0.67 inches with a tolerance of 0.0002 inches, and the overall length is 2.0 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in calibrated inspection environments. Metrology technicians, machinists, and quality control personnel use this type of gage as part of incoming inspection, in-process verification, and final part acceptance workflows.

This plug gage is used in manufacturing and machine shop environments where hole diameter conformance must be verified against tight tolerances. It is appropriate for go inspection of features in both production and toolroom settings. Compatible measuring applications include use alongside set micrometers, verniers, and other precision measuring devices where a reference standard is needed. The Class ZZ Plus classification indicates it meets ASME B89.1 dimensional standards for gage accuracy and surface finish, with a 10 microinch finish on the gage member.

Compatibility

Designed for go inspection applications and for use as a reference standard with set micrometers, verniers, and other precision measuring devices in toolroom and production inspection settings.

Installation Notes

Plug gages of this type are handled and used by metrology technicians and quality control personnel, not installed in mechanical systems. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage member and the workpiece bore before gaging to avoid false readings from debris or cutting fluid. Refer to ASME B89.1 and your facility calibration procedures for proper gage handling, storage intervals, and recalibration schedules.
