Vermont Gage 111285100 Class Zz Minus Plug Pin Gage 0.8510 in

Product Description

The VERMONT GAGE 111285100 is a Class ZZ Minus plug pin gage machined for NoGo inspection work. It measures 0.8510 inches in diameter with an overall length of 2 inches and holds a tolerance of 0.0002 inches. Made from steel, this gage is used to verify that a bored or reamed hole does not exceed its maximum material condition limit. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming dimensional conformance at the time of manufacture. Machinists, quality technicians, and tool-and-die professionals rely on this style of pin gage for fast, repeatable go/nogo decisions on production and inspection floors.

This pin gage is suited for dimensional inspection in manufacturing and machining environments where hole diameter acceptance must be verified to close tolerances. In addition to NoGo hole inspection, the 111285100 is appropriate for setting and checking micrometers, verniers, and other precision measuring devices that require a certified reference standard. It fits naturally into both incoming inspection workflows and in-process quality control routines.

Key Features

Compatibility

Designed for use in NoGo hole inspection applications and as a reference standard for setting micrometers, verniers, and similar precision measuring devices where a certified 0.8510-inch diameter reference is required.

Installation Notes

Pin gages are handled and deployed by quality technicians and machinists in inspection or production settings. Clean the gage and the workpiece bore before use to prevent contamination from affecting the measurement result. Store the gage in its protective case when not in use to avoid surface damage or dimensional change from impacts. Do not force a pin gage into a hole; improper handling can damage both the gage and the workpiece.
