Vermont Gage 111158800 Class Zz Plus Plug Gage 0.588 in

Product Description

The VERMONT GAGE 111158800 is a Class ZZ Plus plug gage designed for precise dimensional inspection of bored holes and machined features measuring 0.588 inches in diameter. Manufactured from tool steel, this gage holds a tolerance of 0.0002 inches and features a 10 microinch surface finish, making it suitable for go inspection applications requiring tight verification standards. Overall length is 2.0 inches. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming conformance to ASME B89.1. Machinists, quality control technicians, and tool-and-die professionals rely on plug gages of this class for fast, repeatable pass/fail checks at the bench or on the floor.

This gage is intended for go inspection use, verifying that a bored or reamed feature accepts the nominal diameter without interference. It is also suited for setting and calibrating micrometers, verniers, and other precision measuring devices. Applications span precision machining shops, aerospace component inspection, toolroom calibration, and general manufacturing quality control where ASME B89.1 compliance is required. The compact 2.0-inch overall length makes it easy to handle in benchtop and inline inspection setups.

• Suitable for setting micrometers, verniers, and other measuring instruments

Compatibility

Designed for go inspection of features at 0.588 inches nominal diameter, and for use as a setting master with micrometers, verniers, and other precision measuring devices as stated in the product application data.

Installation Notes

Plug gages are handled and used by quality control technicians and machinists; no power source or mechanical installation is required. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage and the workpiece bore before inspection to avoid false readings caused by chips or debris. Do not force the gage into an undersize feature, as this can damage the gage surface and invalidate the calibration certificate.
