Vermont Gage 111146400 Class Zz Plus Plug Gage 0.464 in

Product Description

The VERMONT GAGE 111146400 is a Class ZZ Plus plug gage machined from tool steel for precision dimensional inspection. It measures shaft and hole diameters at 0.464 inches with a tolerance of 0.0002 inches, meeting the tight accuracy requirements expected on the shop floor. The gage carries a 10 microfinish surface rating and ships with a Certificate of Accuracy backed by NIST traceability, satisfying documentation requirements for calibrated inspection environments. Machinists, quality technicians, and tool room personnel use plug gages like this one to verify bore size quickly and reliably without the setup time of a full measuring stack.

This plug gage is suited for go inspection of precision bores in manufacturing, toolroom, and quality control environments. It serves as a direct reference standard when setting micrometers, verniers, and other measuring devices to a known diameter. Typical applications include incoming inspection, in-process verification, and final part acceptance across general metalworking, aerospace, and automotive component production. The 2.0-inch overall length provides sufficient handle for comfortable single-hand use in most bore access situations.

Key Features

• Class ZZ Plus tolerance grade — 0.0002 inches tolerance for reliable go inspection
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface for consistent, repeatable contact with bore surfaces
• Meets ASME B89.1 standards for dimensional gaging
• Includes Certificate of Accuracy with NIST traceability for calibration records
• 2.0-inch overall length suited for open-bore and bench inspection use

Compatibility

Designed for go inspection of 0.464-inch diameter bores and for setting micrometers, verniers, and other measuring devices requiring a traceable reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and toolroom machinists — no permanent installation is required. Clean the gage and the bore thoroughly before use to prevent false readings caused by debris or oil buildup. Store the gage in its protective case when not in use to guard the precision ground surface from nicks and corrosion. Follow your facility calibration schedule and re-certify against NIST-traceable standards at intervals appropriate to usage frequency.
