Vermont Gage 111178800 Class Zz Plus Plug Gage 0.788 in

Product Description

The VERMONT GAGE 111178800 is a Class ZZ Plus plug gage designed for precision dimensional inspection of 0.788-inch diameter bores and holes. Built from tool steel and finished to a 10 microfinish surface quality, this gage delivers a tolerance of 0.0002 inches, making it suitable for close-tolerance Go inspection work. At 2.0 inches overall length, it is compact enough for bench use and easy to handle during line inspection. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming the measurement integrity required for quality-controlled environments. Machinists, tool and die makers, and quality technicians install and use this gage in production and inspection settings.

This plug gage is used in manufacturing and machine shop environments where bore diameter verification is required before assembly or final acceptance. It is appropriate for residential and commercial production floors, tool rooms, and metrology labs. The 0.788-inch diameter size suits applications involving precision-bored components, bushings, and housings. Compatible with Go inspection routines and usable alongside set micrometers, verniers, and other calibrated measuring devices as a reference standard.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for high-accuracy Go inspection
• Tool steel construction for durability and wear resistance under repeated use
• 10 microfinish surface finish reduces measurement error from surface variation
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Meets ASME B89.1 standards for plain plug gage dimensional requirements
• Compact 2.0-inch overall length for easy handling at the bench or on the line

Compatibility

Designed for Go inspection applications and for use as a reference standard alongside set micrometers, verniers, and other measuring devices requiring a known 0.788-inch diameter reference.

Installation Notes

Plug gages are handled and used by machinists and quality inspection personnel following standard metrology practices. Store and handle with care to prevent surface damage that would affect gage accuracy. Clean the gage and the bore being inspected before use to remove chips, oil, or debris. Periodically re-verify the gage against its Certificate of Accuracy and re-calibrate per your facility quality program.
