Vermont Gage 112415930 Class Zz Minus Plug Pin Gage 15.93mm

Product Description

The VERMONT GAGE 112415930 is a Class ZZ Minus plug pin gage designed for NoGo inspection of machined bores and holes with a nominal diameter of 15.93 mm. Manufactured from steel with a 10 micro coating finish, this pin gage delivers a tolerance of 0.00508 mm, meeting Class ZZ specifications for general-purpose dimensional inspection. The overall length is 2 inches, making it a compact, hand-held tool suited for use on the shop floor or in a metrology lab. Each unit ships with a Certificate of Accuracy traceable to NIST standards. Machinists, quality control technicians, and toolroom professionals use this gage as part of go/no-go inspection routines.

This pin gage is used in manufacturing and precision machining environments where bore acceptance or rejection must be confirmed quickly and reliably. Its primary application is NoGo inspection, verifying that a hole or bore does not exceed the maximum allowable material condition. It is also suited for setting and checking micrometers, verniers, and other measuring devices requiring a known reference diameter. Typical install scenarios include incoming inspection, in-process quality checks, and final part verification in both job shop and production environments.

Installation Notes

Pin gages are used by machinists and quality technicians and require no permanent installation. Clean the gage and the part bore before use to prevent measurement errors caused by debris or oil film. Store the gage in its protective case when not in use to avoid surface damage that could affect accuracy. Calibration intervals should follow your facility quality management system and applicable measurement standards.
