Vermont Gage 112210400 Class Zz Minus Plug Pin Gage 10.40mm

Product Description

The VERMONT GAGE 112210400 is a Class ZZ minus plug pin gage machined for NoGo inspection applications. It measures 10.40 mm in diameter with a tolerance of 0.00508 mm, making it suitable for verifying that bores and holes do not fall below a specified minimum size. The body is constructed from steel with a 10 microfinish surface coating for consistent contact and wear resistance. At 2 inches in overall length, the gage is sized for handheld use in shop or inspection environments. Each unit ships with a Certificate of Accuracy traceable to NIST standards.

This plug pin gage is designed for dimensional inspection work in manufacturing, machining, and quality control settings. It is used alongside set micrometers, verniers, and other precision measuring devices to verify bore tolerances during incoming inspection, in-process checks, or final acceptance. The Class ZZ designation applies to gages intended for general-purpose inspection rather than high-precision master gage work. Typical users include machinists, quality technicians, and metrology lab personnel working with metric-dimensioned components.

Compatibility

Designed for use with set micrometers, verniers, and other precision measuring devices requiring a 10.40 mm diameter NoGo reference standard.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists and require no installation in the traditional sense. Store the gage in a protective case when not in use to prevent surface damage or corrosion that could affect measurement accuracy. Clean the gage and the bore being checked before use to remove chips, oil, or debris. Do not force the gage into a hole; resistance indicates the bore is at or below the minimum acceptable size.
