Vermont Gage 141250200 Class X Minus Pin Gage 0.502 in

Product Description

The VERMONT GAGE 141250200 is a Class X Minus pin gage used to verify bore diameters, hole sizes, and feature tolerances in precision machining and inspection applications. It measures 0.502 inches in diameter and 2 inches in length, with a tolerance of -0.00004 inches, meeting the tight requirements of Class X Minus classification. The gage is manufactured from tool steel with a 4 microinch surface finish. Each unit ships with a Certificate of Accuracy with NIST traceability, making it suitable for use in quality-controlled environments where documented calibration standards are required.

This pin gage is used in metrology labs, machine shops, and on the production floor to verify hole diameters or calibrate measuring equipment directly. It is appropriate for both incoming inspection and in-process quality checks where close-tolerance verification is needed. Typical users include quality technicians, machinists, and calibration personnel working in precision manufacturing, aerospace, automotive, or general industrial settings.

Key Features

• Class X Minus tolerance of -0.00004 inches for high-accuracy inspection work
• 0.502 inches diameter with 2 inches usable length
• Tool steel construction for durability and dimensional stability
• 4 microinch surface finish for consistent, repeatable contact measurement
• Includes Certificate of Accuracy with NIST traceability for documented calibration compliance

Compatibility

Designed as an OEM-style replacement or direct-use pin gage for calibration of measuring equipment or direct gaging of parts requiring a 0.502-inch nominal hole size verification.

Installation Notes

Pin gages should be handled with clean, dry hands or cotton gloves to prevent surface corrosion from skin oils. Before use, inspect the gage for nicks or burrs that could affect measurement accuracy. Store in the provided case or a protected environment when not in use. No power tools or mechanical force should be used during insertion into a feature being gaged.
