Vermont Gage 112404630 Class Zz Minus Plug Pin Gage 4.63 Mm

Product Description

The VERMONT GAGE 112404630 is a Class ZZ minus plug pin gage designed for precision dimensional inspection in machine shops, quality labs, and production environments. The gage measures 4.63 mm in diameter with a tolerance of 0.00508 mm, making it suitable for NoGo inspection applications where tight dimensional verification is required. Constructed from steel with a 10 microfinish surface coating, it delivers consistent, repeatable measurements. Each unit ships with a Certificate of Accuracy that carries NIST traceability, supporting documentation requirements in ISO and quality-management environments. Metrology technicians and quality control professionals are the primary installers and users of this tool.

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 suited for setting and verifying micrometers, verniers, and other measuring devices that require a certified reference standard. The 4.63 mm diameter makes it applicable in precision machining and assembly operations where small-bore tolerances must be confirmed before parts advance in the production process. Its compact overall length of 2 inches allows use in tight clearances and standard gage block fixtures.

Compatibility

Designed for use in NoGo inspection routines and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring a certified 4.63 mm diameter reference.

Installation Notes

Pin gages are handled and used by metrology technicians and quality control personnel. Always clean the gage and the bore or measuring device contact surfaces before use to prevent debris from affecting measurement accuracy. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity. Do not force the gage into a bore, as this can cause galling or damage to the gage or workpiece.
