Vermont Gage 141162300 Class X Plus Pin Gage 0.623 in

Product Description

The VERMONT GAGE 141162300 is a Class X Plus precision pin gage used to verify bore diameters, check hole sizes, and calibrate measuring equipment. Manufactured from tool steel with a 4 micro-inch surface finish, this pin holds a diameter of 0.623 inches with a tight tolerance of plus 0.00004 inches. Each unit ships with a Certificate of Accuracy with NIST traceability, making it suitable for use in quality control environments, metrology labs, and production floor inspection. Machinists, quality technicians, and calibration professionals rely on this type of gage to confirm dimensional conformance on machined parts and fixtures.

This pin gage is designed for direct gaging of drilled, reamed, or bored holes and for calibrating measuring instruments where a precise reference diameter is required. It is commonly used in machine shops, toolrooms, manufacturing facilities, and calibration laboratories. The 2-inch length provides adequate handling clearance in most inspection applications. Both light industrial and precision manufacturing environments rely on Class X Plus gages where the tightest dimensional accuracy is specified by the inspection plan.

Key Features

• Class X Plus tolerance of plus 0.00004 inches for high-accuracy dimensional inspection
• Tool steel construction for hardness and wear resistance in repeated use
• 4 micro-inch surface finish for consistent, reliable contact measurement
• Includes Certificate of Accuracy with NIST traceability for documented quality assurance
• 0.623-inch diameter and 2-inch length suitable for a wide range of bore inspection tasks

Compatibility

Designed as an OEM-style Class X Plus pin gage for use in bore inspection and calibration applications requiring a 0.623-inch reference diameter.

Installation Notes

Pin gages should be handled with clean cotton gloves or lint-free cloth to prevent corrosion from skin oils. Store in a protective case away from temperature extremes to preserve dimensional stability. Do not force the pin into a hole smaller than its nominal diameter, as this will damage both the gage and the workpiece. Periodic cleaning and re-certification per your facility calibration schedule is recommended to maintain NIST traceability compliance.
