Vermont Gage 111127000 Class Zz Plus Plug Gage 0.27 in

Product Description

The VERMONT GAGE 111127000 is a Class ZZ Plus plug gage designed to verify bore and hole dimensions with high precision. Built from tool steel and finished to a 10 microfinish surface quality, this gage delivers a nominal measurement diameter of 0.27 inches with a tolerance of 0.0002 inches. It ships with a Certificate of Accuracy traceable to NIST, confirming that the gage meets ASME B89.1 dimensional standards. Machinists, quality inspectors, and metrologists use this style of plug gage as a reliable go-inspection reference tool on the shop floor or in a calibration environment.

This plug gage is suited for go inspection applications where a consistent, repeatable reference standard is required. It is also used to set and verify micrometers, verniers, and other measuring devices. With an overall length of 2.0 inches, the 111127000 is a compact, hand-held instrument appropriate for light industrial, precision machining, and quality control applications. It fits readily into standard gage-block workflows and dimensional inspection routines in both production and toolroom settings.

Key Features

• Class ZZ Plus tolerance grade — 0.0002 inches tolerance for precise dimensional verification
• 10 microfinish surface treatment reduces wear and maintains gage accuracy over repeated use
• Tool steel construction provides hardness and durability for shop-floor environments
• Includes Certificate of Accuracy with NIST traceability, meeting ASME B89.1 requirements
• Compact 2.0-inch overall length suits hand-held and bench inspection use

Compatibility

Designed for go inspection of 0.27-inch nominal bore and hole diameters. Also used to set and verify micrometers, verniers, and other dimensional measuring devices per standard shop inspection practice.

Installation Notes

Plug gages of this type are handled and used by quality inspectors, machinists, and metrologists — no power tools or electrical shutoff procedures apply. Store the gage in its protective case when not in use to prevent nicking the finished surface. Clean the gage and the workpiece bore with a lint-free cloth before each measurement to avoid false readings caused by debris or oil film. Follow the calibration interval and handling procedures outlined in ASME B89.1 to maintain traceability.
