Vermont Gage 111167100 Class Zz Plus Plug Gage 0.671 in

Product Description

The VERMONT GAGE 111167100 is a Class ZZ Plus plug gage designed for precision dimensional inspection of hole diameters. Built from tool steel with a 10 microfinish surface finish, this gage measures a nominal diameter of 0.671 inches and holds a tolerance of 0.0002 inches. It is used to verify that bored, drilled, or reamed holes fall within acceptable size limits. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for documented quality control programs. Machinists, quality technicians, and tool-and-die trades rely on this type of gage for repeatable, traceable go-type inspection work.

This plug gage is built for go inspection applications and is also suited for setting and verifying micrometers, verniers, and other precision measuring devices. At 2.0 inches overall length and 0.671 inches diameter, it fits standard gage handle systems used in light manufacturing, job shop, and inspection room environments. The Class ZZ Plus classification indicates it meets ASME B89.1 tolerancing standards for working gages used in production inspection.

Key Features

• Class ZZ Plus tolerance rating per ASME B89.1 for working gage applications
• 0.0002 inch tolerance for precise dimensional verification
• 10 microfinish surface finish for consistent gage contact and wear resistance
• Tool steel construction for durability in production environments
• Includes Certificate of Accuracy with NIST traceability for documented QC compliance
• Suitable for go inspection of holes, and for setting micrometers, verniers, and other measuring devices

Compatibility

Designed as an OEM-style go plug gage for use with standard gage handle systems; compatible with go inspection setups requiring a 0.671 inch nominal diameter gage member conforming to ASME B89.1 Class ZZ Plus standards.

Installation Notes

Plug gages are handled and used by quality technicians and precision machinists. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel. Do not force the gage into a hole; go gages should enter under their own weight or with light hand pressure only. Store in a protective case away from temperature extremes to maintain dimensional stability and NIST-traceable accuracy.
