Vermont Gage 112404450 Class Zz Minus Plug Pin Gage 4.45 Mm

Product Description

The VERMONT GAGE 112404450 is a Class ZZ minus plug pin gage ground to a diameter of 4.45 mm with a minus tolerance of 0.00508 mm. It is used to verify that a hole or bore falls within its specified dimensional limits. The gage is machined from steel and finished to a 10 microfinish surface for consistent, repeatable contact. Each unit ships with a Certificate of Accuracy traceable to NIST standards. Metrologists, quality technicians, and precision machinists use this type of gage during incoming inspection, in-process checks, and final part verification.

This pin gage is suited for NoGo inspection applications where the gage must not enter an acceptable hole. It is also used to set and verify micrometers, verniers, and other dimensional measuring devices. The minus classification means the gage is manufactured to the lower side of the nominal diameter, which is the correct orientation for a NoGo member. Typical use environments include machine shops, quality labs, and production floors working to close-tolerance specifications in both ferrous and non-ferrous part inspection.

Key Features

• Class ZZ minus tolerance ground to 0.00508 mm for NoGo gage applications
• 4.45 mm nominal diameter, 2 inches overall length
• Steel construction with 10 microfinish surface for low wear and consistent contact
• Includes Certificate of Accuracy with NIST traceability
• Compatible with setting micrometers, verniers, and other precision measuring devices

Compatibility

Designed for use in NoGo inspection routines and as a reference setting standard for micrometers, verniers, and other dimensional measuring instruments requiring a 4.45 mm reference.

Installation Notes

Pin gages are handled by quality technicians and precision measurement personnel. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean contact surfaces with a lint-free cloth before use to ensure accurate measurement. Never force the gage into a bore, as this can damage the gage and invalidate its tolerance class.
