Vermont Gage 111276800 Class Zz Minus Plug Pin Gage 0.7680 in

Product Description

The VERMONT GAGE 111276800 is a Class ZZ minus plug pin gage ground to a nominal diameter of 0.7680 inches with a tolerance of 0.0002 inches. This single-end pin gage is used to verify that a hole or bore does not exceed its maximum allowable size, functioning as a NoGo member in a pass/fail inspection routine. Manufactured from steel and finished to 10 microinch surface roughness, it delivers reliable dimensional accuracy for quality control and incoming inspection work. Each gage ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in ISO and AS9100 regulated environments.

This plug pin gage is suited for production floor inspection, tool room verification, and calibration lab use. Its 0.7680-inch diameter makes it appropriate for checking machined bores, drilled holes, and reamed features in metal or plastic components. The gage is also used to set and verify micrometers, vernier calipers, and other comparative measuring devices. Machinists, quality technicians, and metrologists working in general manufacturing, aerospace, automotive, and precision machining shops will find this gage a standard bench tool for dimensional verification tasks.

Key Features

• Class ZZ minus tolerance ground to 0.0002 inches for NoGo inspection applications
• 0.7680-inch nominal measurement diameter for bore and hole verification
• Steel construction finished to 10 microinch surface roughness
• 2-inch overall length for stable hand-held use
• Includes Certificate of Accuracy with NIST traceability for compliant documentation
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for use as a NoGo plug gage in standard bore inspection routines and as a setting reference for micrometers, vernier calipers, and similar measuring instruments requiring a 0.7680-inch reference standard.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists and require no permanent installation. Store the gage in its protective case when not in use to prevent surface damage. Clean the gage and the feature being measured before use to avoid false readings from debris or oil film. Handle with care to avoid dropping, which can alter the ground diameter and void traceability.
