Vermont Gage 111252900 Class Zz Minus Plug Pin Gage 0.5290 in

Product Description

The VERMONT GAGE 111252900 is a Class ZZ Minus plug pin gage manufactured from steel and used to perform NoGo inspection of bored holes and machined features. At 0.5290 inches in diameter with a tolerance of 0.0002 inches, this gage provides a reliable go/no-go reference for verifying that a hole or bore does not exceed its maximum allowable size. The 2-inch overall length gives the technician a secure grip during use. Each unit ships with a Certificate of Accuracy that carries NIST traceability, meeting documentation requirements for quality-controlled shop floors and calibration labs.

This plug pin gage is suited for use in manufacturing, machine shops, inspection departments, and toolrooms where hole diameter verification is required. It is also used to set and verify micrometers, verniers, and other dimensional measuring devices. The Class ZZ tolerance grade is appropriate for general-purpose inspection work. The 10 micro surface finish on the gage pin reduces wear during repeated insertion and helps maintain accuracy over time. Machinists, quality technicians, and metrology professionals are the primary users of this tool.

Installation Notes

Plug pin gages are handled and used by machinists and quality technicians and do not require permanent installation. Store the gage in a protective case when not in use to prevent surface damage. Clean the gage pin and the bore being checked before each use to avoid measurement error caused by debris or coolant residue. Never force the gage into a bore, as this can damage both the gage and the workpiece.
