Vermont Gage 111437650 Class Zz Minus Plug Pin Gage 0.3765 in

Product Description

The VERMONT GAGE 111437650 is a Class ZZ Minus plug pin gage machined from steel for NoGo inspection applications. With a measurement diameter of 0.3765 inches and an overall length of 2 inches, this gage is used to verify that a bore or hole does not fall below the minimum acceptable size. The tolerance held to this gage is 0.000200 inches, consistent with Class ZZ specifications. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality-system documentation requirements. The 10 microfinish surface treatment reduces wear and maintains dimensional integrity across repeated insertions.

This plug pin gage is suited for production floor inspection, incoming quality control, and toolroom verification tasks. Machinists, quality technicians, and tool and die professionals use Class ZZ minus gages when setting micrometers, verifying verniers, and calibrating other measuring devices. The NoGo application means the gage is used to confirm rejection of undersized features, making it a critical component in go/no-go gage sets and dimensional audit routines in both job shop and production environments.

Key Features

• Class ZZ Minus tolerance class — 0.000200 inch tolerance for NoGo inspection use
• 0.3765 inch measurement diameter for precise bore and hole verification
• Steel construction with 10 microfinish surface for durability and consistent contact
• Certificate of Accuracy included with NIST traceability for quality-system compliance
• Compact 2 inch overall length suits benchtop and in-process inspection workflows
• Sold individually — single-unit packaging supports targeted replacement or gage set builds

Compatibility

Designed for NoGo inspection use and for setting and verifying micrometers, verniers, and other dimensional measuring devices requiring a 0.3765 inch reference diameter.

Installation Notes

Plug pin gages are handled and deployed by quality technicians and machinists — no power tools or mechanical installation is required. Clean the gage and the feature being inspected before use to prevent debris from affecting readings or causing surface damage. Store the gage in its case when not in use to protect the precision ground surface and maintain NIST-traceable certification validity. Refer to your quality management system procedures for calibration interval and documentation requirements.
