Vermont Gage 141100000 Class X Plus Pin Gage 1 in

Product Description

The VERMONT GAGE 141100000 is a Class X Plus precision pin gage machined from tool steel to a nominal diameter of 1.0000 inches with a tolerance of +0.00004 inches. At 2 inches in length and weighing 0.1 pounds, it is sized for direct hand use or fixture insertion. Each unit ships with a Certificate of Accuracy that carries NIST traceability, satisfying documentation requirements in calibrated metrology labs and quality inspection environments. The surface finish is held to 4 micro-inch Ra, supporting reliable, repeatable contact measurement. Machinists, metrologists, and quality technicians use this gage to verify hole sizes, bore diameters, and feature locations to close tolerances.

This pin gage is suited for dimensional inspection in manufacturing, tool-and-die, aerospace, automotive, and general metrology applications. Its primary roles are calibration of measuring equipment and direct gaging of machined parts. The tight Class X Plus tolerance makes it appropriate where standard Class X gages do not provide sufficient accuracy margin. It is equally at home on a surface plate, in a gage block setup, or as a transfer standard in a controlled calibration lab.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-precision dimensional verification
• Tool steel construction provides wear resistance and dimensional stability
• 4 micro-inch Ra surface finish ensures consistent, low-friction contact
• Includes Certificate of Accuracy with NIST traceability for audit and calibration records
• Compact 2-inch length suits both bench inspection and fixture use

Compatibility

Designed as an OEM-style replacement or supplemental standard for use with standard pin gage handle sets and precision inspection fixtures accepting 1-inch diameter gage pins.

Installation Notes

Pin gages should be handled with clean cotton gloves or lint-free cloths to prevent corrosion from skin oils. Store the gage in its protective case when not in use and allow it to thermally stabilize to the inspection environment before measurement. Calibration intervals should follow the facility quality management plan; re-certification against NIST-traceable standards is recommended on a scheduled basis. Cleaning with a lint-free cloth and light instrument oil after use extends service life.
