Vermont Gage 112409950 Class Zz Minus Plug Pin Gage 9.95 Mm

Product Description

The VERMONT GAGE 112409950 is a Class ZZ Minus plug pin gage designed for dimensional inspection of machined bores and holes at 9.95 mm diameter. Built from steel with a 10 microfinish surface coating, it delivers a tolerance of 0.00508 mm, meeting Class ZZ minus standards for NoGo inspection applications. At 2 inches overall length and weighing 0.07 pounds, this pin gage is sized for bench and in-process inspection work. Each unit ships with a Certificate of Accuracy with NIST Traceability, making it suitable for quality-controlled environments where documentation is required. Machinists, quality technicians, and tool room professionals are the primary users.

This pin gage is used in NoGo inspection routines to verify that a bore or hole does not exceed its maximum allowable size. It is also used for setting and calibrating micrometers, verniers, and other measuring devices requiring a traceable reference. Typical applications include production floor inspection, incoming material verification, and metrology lab use in manufacturing, aerospace, automotive, and general machining environments. The 9.95 mm diameter makes it suitable for close-tolerance bore inspection where precise go/no-go gauging decisions are required.

Key Features

• Class ZZ Minus tolerance of 0.00508 mm for accurate NoGo inspection
• Steel construction with 10 microfinish surface coating for consistent contact and wear resistance
• Includes Certificate of Accuracy with NIST Traceability for quality documentation compliance
• 2 inches overall length suitable for standard bore gauging tasks
• Compatible with setting micrometers, verniers, and other precision measuring devices

Compatibility

Designed for use in NoGo inspection applications and for setting micrometers, verniers, and other precision measuring devices requiring a 9.95 mm traceable reference standard.

Installation Notes

Pin gages are handled and stored by quality technicians and tool room personnel following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the gage into a bore; a proper NoGo gage should not enter a correctly sized hole. Store in the supplied case or a designated gage stand to prevent contact damage to the finished surface.
