Vermont Gage 112403010 Class Zz Minus Plug Pin Gage 3.01mm

Product Description

The VERMONT GAGE 112403010 is a Class ZZ minus plug pin gage ground to a 3.01 mm diameter with a tolerance of 0.00508 mm. It is a single-pin, go/no-go style inspection tool used to verify bore and hole dimensions in machined parts. The gage is manufactured from steel with a 10 microfinish surface coating, giving it wear resistance suitable for repeated inspection cycles. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting documentation requirements for quality-controlled manufacturing environments. Metrology technicians and machinists use this gage as part of incoming inspection, in-process checks, or final part verification.

This pin gage is rated for NoGo inspection applications and is also suited for setting micrometers, verniers, and other measuring devices that require a traceable reference. At 2 inches overall length, it fits standard pin gage handles and is appropriate for benchtop and floor-level inspection tasks in machine shops, tool rooms, and production facilities. Its Class ZZ minus designation means the gage is ground undersize from nominal, making it a NoGo member for checking that a hole has not been bored oversize.

Key Features

Compatibility

Designed for use with standard plug gage handles and compatible with inspection setups requiring a 3.01 mm NoGo pin reference, including micrometer and vernier setting applications.

Installation Notes

Pin gages should be inserted and withdrawn along the axis of the hole without lateral force to prevent wear or deflection errors. Clean the gage and the bore being checked before use to remove chips, coolant, or debris that could affect the reading. Store the pin in its protective case when not in use to prevent surface damage. Handle with clean cotton gloves or a clean cloth to avoid corrosion from skin oils.
