Vermont Gage 111232900 Class Zz Minus Plug Gage 0.3290 in

Product Description

The VERMONT GAGE 111232900 is a Class ZZ minus plug pin gage ground to a nominal diameter of 0.3290 inches with a tolerance of 0.0002 inches. It is manufactured from steel and measures 2 inches in overall length. Plug pin gages of this class are precision dimensional inspection tools used by machinists, quality technicians, and metrology professionals to verify hole sizes and check NoGo conditions on drilled, reamed, or bored features. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming the gage meets Class ZZ dimensional standards at the time of manufacture.

This gage is suited for NoGo inspection of holes at or near the 0.3290-inch nominal diameter. It is also used to set and verify micrometers, verniers, and other dimensional measuring devices in shop or laboratory environments. Typical applications include incoming inspection, in-process quality checks, and calibration support in manufacturing, toolroom, and metrology settings. The 10 microfinish surface finish on the gage pin helps ensure consistent, repeatable contact during measurement without scoring the bore surface.

Compatibility

Designed for use as a NoGo plug pin gage for holes at the 0.3290-inch nominal diameter, and for setting or verifying micrometers, verniers, and other precision measuring devices per the manufacturer specifications.

Installation Notes

Plug pin gages are handled and used by qualified machinists or metrology technicians following established inspection procedures. Store the gage in its protective case when not in use to prevent surface damage. Apply a light coat of instrument oil when storing to prevent corrosion on the steel surface. Never force the gage into a bore; light hand pressure only is appropriate to avoid damaging the gage or the workpiece.
