Vermont Gage 112306750 Class Zz Plus Plug Gage 6.75 Mm

Product Description

The VERMONT GAGE 112306750 is a Class ZZ Plus plug gage designed for precision inspection of hole diameters in manufacturing and quality control environments. Manufactured from tool steel with a 10 microfinish surface, this gage checks a 6.75 mm diameter bore to a tolerance of 0.00508 mm. It measures 2.0000 inches in overall length, making it a compact, handheld inspection tool. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documented quality assurance programs. Machinists, tool and die makers, and quality technicians use this gage for go inspection work in production and inspection settings.

This plug gage is suited for go inspection applications where close-tolerance hole verification is required. It is also compatible with setup and calibration routines for micrometers, verniers, and other precision measuring devices. The 6.75 mm diameter and Class ZZ Plus tolerance class make it appropriate for moderate-precision bore verification on machined parts in both job shop and production floor environments. Single-unit packaging supports individual tool crib stocking or direct bench use.

Key Features

• Class ZZ Plus tolerance class with 0.00508 mm tolerance for reliable go inspection
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface for smooth, repeatable gage entry
• 2.0000 inch overall length for easy single-hand use
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Conforms to ASME B89.1 standards

Compatibility

Designed as an OEM-style go plug gage for verifying 6.75 mm diameter bores and for use in setting micrometers, verniers, and other precision measuring devices per ASME B89.1.

Installation Notes

Plug gages of this type are handled and used by quality technicians and machinists - no power tools or electrical shutoff is required. Store the gage in its protective case when not in use to prevent surface damage or contamination. Clean the gage and the bore with a lint-free cloth before inspection to avoid false readings. Handle with care to prevent drops, which can alter the gage diameter and void NIST traceability.
