Vermont Gage 111264800 Class Zz Minus Plug Pin Gage 0.6480 in

Product Description

The VERMONT GAGE 111264800 is a Class ZZ minus plug pin gage designed for NoGo inspection applications in precision measurement and quality control work. Manufactured from steel, this pin gage measures a nominal diameter of 0.6480 inches with a tolerance of 0.0002 inches, providing the tight dimensional control required for verifying bore and hole rejections. The overall length is 2 inches. Each unit ships with a Certificate of Accuracy that carries NIST traceability, making it suitable for use in calibrated inspection environments. Machinists, quality technicians, and toolroom professionals use this type of gage as part of a Go/NoGo inspection routine or to set and verify micrometers, verniers, and other precision measuring devices.

This pin gage is used in manufacturing, toolroom, and quality assurance settings where dimensional verification of holes, bores, and features is required. Class ZZ is a working-gage grade appropriate for production floor inspection and shop-floor measurement tasks. The minus designation means the gage is ground to the minus side of the nominal diameter, which is the correct configuration for a NoGo gage member. It is also used to calibrate or set measuring instruments such as micrometers and vernier calipers when a known reference diameter is needed.

Key Features

• Nominal diameter of 0.6480 inches with 0.0002-inch tolerance
• Steel construction for durability in shop and toolroom environments
• 10 micro finish coating for consistent surface quality
• Includes Certificate of Accuracy with NIST traceability
• Compatible with micrometers, verniers, and other precision measuring devices

Compatibility

Designed for use in NoGo bore and hole inspection routines and as a setting reference for micrometers, verniers, and other precision measuring devices.

Installation Notes

Pin gages are handled by quality technicians and toolroom machinists and require no power source or mechanical installation. Handle with clean, dry hands or inspection gloves to prevent corrosion from skin oils. Store in a protective case away from other metal tooling to avoid contact damage that could alter the gage surface. Follow your facility calibration schedule and re-verify NIST traceability documentation per applicable quality system requirements.
