Vermont Gage 111310250 Class Zz Plus Plug Gage 0.1025 in

Product Description

The VERMONT GAGE 111310250 is a Class ZZ Plus plug gage designed to measure bores, holes, and internal features with a nominal diameter of 0.1025 inches. Manufactured from tool steel to a 10 microfinish surface finish, this gage delivers a tolerance of 0.0002 inches, making it suitable for precision Go inspection work. It is used to verify that a workpiece hole falls within an acceptable dimensional range. Licensed metrologists, machinists, and quality control technicians rely on plug gages like this one to enforce tight tolerances on production and inspection floors. Each unit ships with a Certificate of Accuracy with NIST traceability, supporting documented quality systems.

This plug gage is appropriate for use in dimensional inspection of machined components where precise bore sizing is critical. It is rated for Go inspection applications and is also suited for calibrating and setting micrometers, verniers, and other measuring instruments. The 2.0-inch overall length provides a practical grip and handling profile for bench and floor inspection tasks. Typical users include quality assurance technicians and precision machinists working in manufacturing, aerospace, automotive, and general metalworking environments.

Compatibility

Designed for Go inspection of bores and holes at 0.1025 inches nominal diameter, and suitable for setting and verifying micrometers, verniers, and other precision measuring devices in accordance with ASME B89.1.

Installation Notes

Plug gages are handled and used by qualified machinists or quality control technicians and do not require installation in the traditional sense. Before use, ensure the gage and workpiece are at the same ambient temperature to prevent thermal expansion errors. Clean the gage and the bore being inspected prior to measurement to avoid debris-induced false readings. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity.
