Vermont Gage 112412870 Class Zz Minus Plug Pin Gage 12.87mm

Product Description

The VERMONT GAGE 112412870 is a Class ZZ Minus plug pin gage with a 12.87 mm measurement diameter, designed for NoGo inspection applications in precision metrology. Built from steel with a 10 micro-inch coating finish, this pin gage delivers a tolerance of 0.00508 mm, making it suitable for verifying that a feature does not exceed its maximum material condition. With an overall length of 2 inches and a package weight of 0.12 pounds, it is a compact, single-piece inspection tool used by quality control technicians, machinists, and metrologists in manufacturing and metrology lab environments.

This pin gage is used in NoGo inspection routines where a hole, bore, or feature must be checked against a maximum limit. Typical applications include verifying drilled or reamed holes, checking machined bores, and confirming dimensional compliance on production parts. It is also suitable for setting and checking micrometers, verniers, and other precision measuring devices. Each gage ships with a Certificate of Accuracy with NIST traceability, supporting documented quality assurance programs and ISO-compliant inspection workflows.

Key Features

• Class ZZ Minus tolerance class at 0.00508 mm for NoGo inspection use
• Steel construction with 10 micro-inch coating finish for wear resistance and dimensional stability
• Includes Certificate of Accuracy with NIST traceability for documented QA programs
• Suitable for setting micrometers, verniers, and other calibrated measuring devices
• Compact 2-inch overall length for easy handling in bench and floor inspection settings

Compatibility

Designed for NoGo inspection of features at 12.87 mm diameter and for use with micrometers, verniers, and other precision measuring devices requiring a traceable reference standard.

Installation Notes

Pin gages are handled and used by quality control technicians and metrologists and do not require mechanical installation. Keep the gage clean and lightly oiled when not in use to prevent corrosion. Store in a protective case away from surfaces that could cause impact damage or dimensional distortion. Always verify gage calibration status before use in a controlled inspection environment.
