Vermont Gage 911225100 Class Zz Minus Plug Pin Gage 0.2510 in

Product Description

The VERMONT GAGE 911225100 is a Class ZZ Minus plug pin gage machined from steel with a black oxide finish, sized at 0.2510 inches in diameter. It is used to verify that a hole or bore does not exceed a specified maximum limit, functioning as a NoGo inspection tool in dimensional quality control. With a tolerance of 0.0002 inches and an overall length of 2 inches, this pin gage delivers the precision required for close-tolerance work. Each unit ships with a Certificate of Accuracy traceable to NIST. Machinists, quality technicians, and metrologists use this gage on the shop floor and in inspection labs.

This pin gage is suited for NoGo inspection applications where a controlled minus tolerance is required. It is also compatible with setting micrometers, verniers, and other precision measuring devices that require a known reference diameter. The black oxide coating provides corrosion resistance and reduces glare during inspection. The 0.2510-inch diameter makes it appropriate for checking bores and holes in close-tolerance machined components across general manufacturing and precision machining environments.

Key Features

• Class ZZ Minus tolerance classification for NoGo inspection use
• 0.2510-inch diameter with a tolerance of 0.0002 inches
• Steel construction with black oxide coating for durability and corrosion resistance
• 2-inch overall length for easy single-hand handling
• Includes Certificate of Accuracy with NIST traceability
• Suitable for setting micrometers, verniers, and other precision measuring devices

Compatibility

Designed for use as a NoGo inspection gage and as a reference standard for setting micrometers, verniers, and other precision measuring instruments requiring a 0.2510-inch diameter reference.

Installation Notes

This gage is handled by quality technicians and metrologists in inspection environments; no installation tools or power shutoff is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain accuracy. Do not force the pin into a bore that resists entry, as this can damage the gage surface and compromise dimensional integrity. Store in the protective case or sleeve to avoid contact with other metal tools.
