Vermont Gage 112218760 Class Zz Minus Plug Pin Gage 18.76mm

Product Description

The VERMONT GAGE 112218760 is a Class ZZ minus plug pin gage used to verify bore and hole dimensions in precision inspection applications. The gage measures 18.76 mm in diameter with a tolerance of 0.00508 mm, making it suitable for high-accuracy NoGo inspection work. At 2 inches in overall length and constructed from steel with a 10 micro coating finish, this pin gage is built for consistent, repeatable use on the shop floor or in a metrology lab. Each unit ships with a Certificate of Accuracy traceable to NIST standards, confirming it meets documented dimensional requirements out of the box.

This pin gage is used in NoGo inspection routines where a bore or hole must be confirmed as not oversized beyond a specified limit. Typical applications include incoming inspection, in-process quality control, and final verification of machined components. It is also suited for setting and verifying micrometers, verniers, and other measuring devices that require a known reference standard. Machinists, quality technicians, and metrology professionals use this gage type across manufacturing, tooling, and precision fabrication environments.

Compatibility

Designed for use in NoGo inspection applications and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring an 18.76 mm reference diameter.

Installation Notes

Pin gages are handled and used by quality technicians and machinists; no power source or mechanical installation is required. Store the gage in its protective case when not in use to prevent surface damage that could affect dimensional accuracy. Clean contact surfaces before use to remove oils, debris, or particulate that could influence readings. Follow your facility calibration schedule and handle the gage by the body, not the measuring surface, to avoid corrosion from skin contact.
