Vermont Gage 111152500 Class Zz Plus Plug Gage 0.525 in

Product Description

The VERMONT GAGE 111152500 is a Class ZZ Plus plug gage designed to verify inside diameter dimensions to a tolerance of 0.0002 inches. Machined from tool steel and finished to a 10 microinch surface finish, this gage delivers consistent, repeatable measurements in precision inspection environments. At 2.0 inches overall length with a 0.525-inch measurement diameter, it is sized for bench use and hand-held inspection work. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Quality control technicians, tool room machinists, and metrology professionals rely on this type of gage for fast, reliable go-inspection checks.

This plug gage is used for go inspection of bored, drilled, reamed, or otherwise finished holes at a nominal diameter of 0.525 inches. It is also suited for setting and verifying micrometers, verniers, and other comparative measuring devices. Typical applications include incoming inspection, in-process quality control, and final inspection in manufacturing, machining, and tooling operations. The compact overall length makes it practical for both production-floor and inspection-room use.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precise go-inspection verification
• Tool steel construction for durability and dimensional stability
• 10 microinch surface finish for consistent gage-to-workpiece contact
• Meets ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection of inside diameters at 0.525 inches nominal, and for use as a reference standard when setting micrometers, verniers, and other measuring devices.

Installation Notes

This gage is handled and used by quality control technicians and tool room personnel — no permanent installation is required. Keep the gage clean and lightly oiled when stored to prevent corrosion of the tool steel surface. Do not force the gage into a bore; apply light, consistent hand pressure only. Store in its case away from temperature extremes to preserve dimensional accuracy and NIST-traceable certification validity.
