Vermont Gage 111152600 Class Zz Plus Plug Gage 0.526 in

Product Description

The VERMONT GAGE 111152600 is a Class ZZ Plus plug gage designed to verify inside diameter dimensions to a tolerance of 0.0002 inches. Built from tool steel with a 10 microfinish surface, this gage delivers consistent, repeatable measurement performance in shop and inspection environments. It measures a nominal diameter of 0.526 inches and comes with a Certificate of Accuracy with NIST traceability, meeting ASME B89.1 standards. Machinists, quality technicians, and metrologists use this type of gage for Go inspection of bored holes, reamed openings, and other precision ID features.

This plug gage is suited for dimensional inspection in manufacturing, toolroom, and quality control settings. It is used to verify that a hole falls within specified tolerance before a part advances in production. Typical applications include Go inspection routines, setting and checking micrometers, verniers, and other measuring devices where a certified reference dimension is required. The overall length of 2.0 inches provides comfortable handling during single-hand use at a workbench or inspection station.

• Conforms to ASME B89.1 dimensional standards
• Overall length of 2.0 inches for ergonomic single-hand use

Compatibility

Designed for use in Go inspection of 0.526-inch nominal inside diameter features and for setting micrometers, verniers, and other measuring devices requiring a certified plug reference.

Installation Notes

Plug gages are handled and stored by quality technicians and toolroom machinists following shop metrology procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into a hole that resists entry, as this can damage both the gage and the workpiece. Store in the provided case or a clean, protected location away from impact hazards to preserve the certified tolerance.
