Vermont Gage 112402450 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 112402450 is a Class ZZ Minus plug pin gage machined from steel and used for precision dimensional inspection. The gage measures a nominal diameter of 2.45 mm with a tolerance of 0.00508 mm, providing reliable go/no-go verification in quality control workflows. At 2 inches in overall length, it is sized for handheld use in inspection stations, tool cribs, and production floor applications. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for ISO-compliant inspection programs. Machinists, quality technicians, and metrology professionals use this gage to verify hole dimensions on machined components and assemblies.

This plug pin gage is intended for NoGo inspection applications, meaning it confirms that a bore or hole does not exceed the upper tolerance limit. It is also suited for setting and verifying micrometers, verniers, and other measuring devices that require a traceable reference standard. Typical environments include precision machining shops, production quality lines, and tool rooms where repeatable, documented measurement is required.

Compatibility

Designed for use in NoGo bore inspection and as a setting reference for micrometers, verniers, and other precision measuring devices requiring a traceable dimensional standard.

Installation Notes

Pin gages are handled by quality technicians and metrology personnel; no installation tools or mechanical fasteners are required. Keep the gage surface clean and free of oils, debris, and burrs before use to avoid false readings or surface damage. Store in a protective case away from magnetic fields and temperature extremes to maintain dimensional stability. Inspect the gage periodically for wear and recertify on a schedule consistent with your facility quality plan.
