Vermont Gage 141102100 Class X Plus Pin Gage 0.021 in

Product Description

The VERMONT GAGE 141102100 is a Class X Plus precision pin gage used to verify bore diameters, check hole sizes, and calibrate measuring equipment to exacting tolerances. Manufactured from tool steel with a 4 micro-inch finish, this pin measures 0.021 inches in diameter and 2 inches in length. The Class X Plus tolerance grade holds a unilateral tolerance of +0.00004 inches, making it suitable for the tightest inspection requirements in metrology and quality control environments. Each pin ships with a Certificate of Accuracy traceable to NIST, supporting documented calibration programs in ISO and AS9100 facilities.

This pin gage is used in tool rooms, quality labs, and on production floors where precise hole or bore verification is required. Typical applications include checking drilled, reamed, or punched holes in machined components, calibrating air gages, and qualifying CMM fixtures. The small 0.021-inch diameter makes this pin appropriate for fine-feature inspection work in aerospace, automotive, medical device, and general manufacturing contexts. Machinists, quality technicians, and calibration specialists are the primary users of this product.

Installation Notes

Pin gages are handled and stored by qualified quality technicians or metrologists following established gage handling procedures. Always clean the pin and the feature being gaged before use to prevent debris from affecting readings or damaging the pin surface. Store in the provided case or a dedicated gage block cabinet away from humidity and contaminants. Do not force the pin into a feature; if resistance is met, inspect the feature and the pin for contamination or burrs before proceeding.
