Vermont Gage 141150200 Class X Plus Pin Gage 0.502 in

Product Description

The VERMONT GAGE 141150200 is a Class X Plus precision pin gage used to verify bore diameters and to calibrate measuring equipment. Machined from tool steel with a 4 micro-inch finish, it holds a tight tolerance of +0.00004 inches on a 0.502-inch nominal diameter. At 2 inches in length, the gage is sized for hand use in inspection and quality-control workflows. Each unit ships with a Certificate of Accuracy that carries NIST traceability, meeting documentation requirements for ISO and other quality management systems. Metrologists, machinists, and quality technicians rely on this gage for direct part inspection and instrument verification.

This pin gage is suited for dimensional inspection in manufacturing, machine shops, and metrology labs. It is used to verify hole sizes, check tooling, and calibrate or confirm the accuracy of measurement equipment such as bore gages and air gages. The 0.502-inch diameter makes it appropriate for close-tolerance bore inspection where a go or no-go determination is required. Both production floor inspection and laboratory calibration environments are typical applications.

Key Features

Compatibility

Designed as an OEM-style replacement or standard addition to pin gage sets used in dimensional inspection of bores and holes requiring a 0.502-inch nominal diameter reference.

Installation Notes

Pin gages require no installation in the traditional sense but should be handled with care to protect the precision-ground surface from nicks, corrosion, and thermal variation. Store in a protective case away from other metal tools. Allow the gage and workpiece to reach the same ambient temperature, typically 68 degrees F per ASME B89 standards, before taking measurements. Clean mating surfaces before use to avoid false readings or surface damage.
