Vermont Gage 111129000 Class Zz Plus Plug Gage 0.29 in

Product Description

The VERMONT GAGE 111129000 is a Class ZZ Plus plug gage designed for dimensional inspection of bored, drilled, and reamed holes. Machined from tool steel, it measures a nominal diameter of 0.29 inches with a tolerance of 0.0002 inches and a surface finish of 10 microfinish. The gage includes a Certificate of Accuracy with NIST traceability, confirming it meets ASME B89.1 standards. It is used in quality control and metrology applications by machinists, toolmakers, and inspection personnel who need reliable go-inspection verification of hole diameters.

This plug gage is suited for go inspection tasks in manufacturing and machine shop environments. It is compatible with standard gage handle systems and can be used alongside set micrometers, verniers, and other precision measuring devices to verify hole size conformance. The 2.0-inch overall length provides a practical reach for typical bore inspection setups in both production and bench inspection settings.

Installation Notes

Plug gages are handled and used by quality control technicians, machinists, and toolroom personnel. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel surface. Do not force the gage into a hole; apply only hand pressure to avoid damaging the gage or the workpiece. Store in a protective case away from temperature extremes to maintain dimensional stability.
