Vermont Gage 141144400 Class X Plus Pin Gage 0.444 in

Product Description

The VERMONT GAGE 141144400 is a Class X Plus precision pin gage manufactured from tool steel for use in dimensional inspection and calibration applications. It measures 0.444 inches in diameter and 2 inches in length, with a tolerance of +0.00004 inches — a specification that places it firmly in the high-precision Class X Plus category. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for ISO-compliant quality systems. A surface finish of 4 micro inch ensures consistent, repeatable contact during measurement. Machinists, quality technicians, and calibration lab personnel are the primary users of this gage.

This pin gage is suited for both shop-floor and laboratory environments where precise go/no-go or direct dimensional verification is required. Typical applications include checking hole diameters, verifying bore sizes, calibrating measuring instruments, and confirming tolerances on machined components. It is appropriate for use in aerospace, automotive, medical device, and general precision manufacturing settings where NIST-traceable documentation is required by quality management standards.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-precision dimensional verification
• Tool steel construction for hardness, wear resistance, and dimensional stability
• 4 micro inch surface finish for accurate, repeatable contact measurements
• Includes Certificate of Accuracy with NIST traceability for quality system compliance
• Compact 2 inch length suitable for bench use and portable inspection kits

Compatibility

Designed as a precision measurement and calibration tool for direct gaging of parts or calibration of measuring equipment in applications requiring a 0.444 inch nominal diameter pin gage.

Installation Notes

Pin gages are handled and stored by quality technicians and calibration professionals — not installed in mechanical systems. Handle with clean cotton gloves or a lint-free cloth to prevent corrosion from skin contact. Store in a protective case away from moisture and temperature extremes. Clean the gage and the feature being measured before use to ensure accurate readings, and verify the gage is at thermal equilibrium with the workpiece before measuring.
