Vermont Gage 112404930 Class Zz Minus Plug Pin Gage 4.93 Mm

Product Description

The VERMONT GAGE 112404930 is a Class ZZ minus plug pin gage designed for NoGo inspection work in precision measurement applications. This steel pin gage measures 4.93 mm in diameter and holds a tolerance of 0.00508 mm, making it suitable for verifying that a bore or hole does not exceed its maximum allowable size. The overall length is 2 inches. Each unit ships with a Certificate of Accuracy that includes NIST traceability, confirming the gage meets documented calibration standards. It is used by quality control technicians, machinists, and metrology professionals who need reliable, repeatable dimensional verification.

This pin gage is applied in NoGo inspection routines where the go/nogo gaging method is used to confirm dimensional conformance on machined bores, drilled holes, and other cylindrical features. It is also suited for setting micrometers, verniers, and other measuring devices that require a certified reference standard. Typical use environments include machine shops, manufacturing quality labs, and tool rooms handling close-tolerance work. The 4.93 mm diameter addresses a specific metric size range commonly found in precision component manufacturing.

• Compatible with use on micrometers, verniers, and other precision measuring devices

Compatibility

Suitable for NoGo inspection applications and for setting micrometers, verniers, and other precision measuring devices requiring a certified 4.93 mm metric reference standard.

Installation Notes

Pin gages are handled and used by quality technicians and machinists in inspection or calibration settings. 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; apply only light, controlled hand pressure to avoid damage to the gage or the workpiece. Store in the original case or a protected holder to maintain surface finish integrity.
