Vermont Gage 112302230 Class Zz Plus Plug Gage 2.23mm

Product Description

The VERMONT GAGE 112302230 is a Class ZZ Plus cylindrical plug gage used to verify bore and hole diameters to tight dimensional tolerances. It checks a 2.23 mm diameter with a tolerance of 0.00508 mm, making it appropriate for Go inspection applications where precise conformance to a minimum acceptable bore size must be confirmed. Machined from tool steel and finished to a 10 microfinish surface, the gage resists wear during repeated use. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and inspection personnel are the primary users of this instrument.

This plug gage is suited for Go inspection tasks in machine shops, production floors, and metrology labs. It is used alongside set micrometers, verniers, and other calibrated measuring devices to verify that bored, drilled, or reamed holes fall within the minimum acceptable dimensional limit. Its 2.0 inch overall length fits standard pin gage handles and fixtures common to bench inspection setups. The 2.23 mm diameter range targets small precision bores typical in close-tolerance mechanical assemblies.

Key Features

Compatibility

Designed for use with set micrometers, verniers, and other calibrated measuring devices in Go inspection applications requiring a 2.23 mm diameter plug gage per ASME B89.1.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power source or trade license is required for operation. Store the gage in its protective case when not in use and avoid dropping or contacting hard surfaces that could alter the ground diameter. Clean the gage and the bore being inspected before use to prevent debris from affecting the reading. Calibration intervals should follow your facility quality management system and applicable metrology standards.
