Vermont Gage 111280700 Class Zz Minus Plug Pin Gage 0.807 in

Product Description

The VERMONT GAGE 111280700 is a Class ZZ Minus plug pin gage machined from steel and used to verify that a bored or reamed hole does not exceed its upper tolerance limit. At 0.8070 inches in diameter with a tolerance of 0.0002 inches, this pin gage delivers the dimensional precision required for NoGo inspection in production and quality-control environments. The 2-inch overall length provides a secure, comfortable grip during use. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in calibrated inspection programs and documented QC workflows.

This plug pin gage is used in machine shops, manufacturing facilities, and metrology labs where hole diameter verification is part of standard part acceptance or rejection protocol. It is designed for NoGo inspection and can also be used to set micrometers, verniers, and other measuring devices to a known reference diameter. Typical applications include incoming inspection, in-process verification, and final part acceptance checks across a range of industries including aerospace, automotive, and general machining.

Compatibility

Designed for use in NoGo plug gage inspection setups and as a reference standard for setting micrometers, verniers, and other dimensional measuring devices to a 0.8070 inch reference diameter.

Installation Notes

Pin gages are handled and used by machinists, quality technicians, and metrologists — no power tools or fasteners are required. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Store in a protective case away from other tooling to avoid surface damage. Allow the gage and workpiece to thermally stabilize to the same ambient temperature before measuring to minimize thermal expansion error.
