Vermont Gage 111151600 Class Zz Plus Plug Gage 0.516 in

Product Description

The VERMONT GAGE 111151600 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bored holes and machined features. At 0.516 inches in diameter and 2.0 inches in overall length, this go-style gage checks whether a feature falls within acceptable tolerance limits. It is manufactured from tool steel and holds a tolerance of 0.0002 inches, meeting ASME B89.1 standards. A 10 microinch surface finish ensures consistent, repeatable contact with the gauging surface. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality documentation requirements in production and inspection environments.

This plug gage is suited for use in machine shops, metrology labs, and manufacturing quality control stations. It is intended for go inspection applications and can also be used to calibrate or verify the accuracy of set micrometers, verniers, and other measuring devices. The compact 2.0-inch overall length makes it easy to handle in bench inspection setups. It is a standard tool for machinists, quality technicians, and metrology professionals working to dimensional tolerances in precision part production.

Compatibility

Designed for go inspection use and suitable for setting and verifying set micrometers, verniers, and other measuring devices requiring a 0.516-inch reference diameter.

Installation Notes

Plug gages should be handled and stored carefully to prevent surface damage or dimensional distortion. Clean the gage and the workpiece bore before use to remove chips, coolant, and debris that could affect measurement accuracy. Do not force the gage into a feature; apply light, consistent hand pressure only. Inspection personnel should allow the gage to reach ambient temperature before use to avoid thermal expansion errors.
