Vermont Gage 111264200 Class Zz Minus Plug Pin Gage 0.6420 in

Product Description

The VERMONT GAGE 111264200 is a Class ZZ minus plug pin gage used to verify that a hole or bore does not exceed its maximum allowable size limit. Classified as a NoGo member, this gage is intended for go/no-go inspection routines in quality control and manufacturing settings. It measures 0.6420 inches in diameter with a tolerance of 0.0002 inches, and an overall length of 2 inches. Constructed from steel and finished to a 10 micro surface finish, it delivers consistent, repeatable results. Each unit ships with a Certificate of Accuracy backed by NIST traceability, meeting typical shop and lab documentation requirements.

This plug pin gage is suited for inspecting bored, drilled, or reamed holes in production and inspection environments. It is also used to set and verify micrometers, verniers, and other precision measuring devices. Machinists, quality technicians, and tool room professionals use this gage in both job shop and production floor applications where tight hole tolerances must be confirmed before parts advance to the next stage of assembly or shipment.

Designed for use in NoGo inspection routines and as a setting reference for micrometers, verniers, and other precision measuring devices where a 0.6420 inch diameter standard is required.

Installation Notes

Plug pin gages are handled and used by machinists and quality control technicians — no power tools or trade licensing is required for use. Store the gage in its protective case when not in use to prevent damage to the precision ground surface. Clean the gage and the part bore before inspection to avoid false readings caused by debris or cutting fluid. Do not force the gage into a bore; a Class ZZ NoGo member should not enter a conforming hole.
