Vermont Gage 141155500 Class X Plus Pin Gage 0.555 in

Product Description

The VERMONT GAGE 141155500 is a Class X Plus pin gage used to check hole diameters and calibrate measuring equipment with high accuracy. It measures 0.555 inches in diameter and 2 inches in length, machined from tool steel with a 4 micro finish. The Class X Plus tolerance of +0.00004 inches places this gage in the tightest commercially available accuracy tier, making it appropriate for quality control labs, calibration rooms, and precision machining environments. Each unit ships with a Certificate of Accuracy traceable to NIST standards. Machinists, quality technicians, and metrology professionals use this gage for go/no-go inspection and instrument calibration.

This pin gage is suited for precision inspection applications in manufacturing, tool rooms, and calibration facilities. It is used to verify bore diameters, qualify inspection fixtures, and serve as a reference standard when calibrating other measuring instruments. The 2-inch length provides adequate grip and handling for use in standard pin gage handles or holders. Its NIST-traceable certificate makes it acceptable for use in ISO 9001 and AS9100 quality management environments where documented traceability is required.

Key Features

• Class X Plus tolerance of +0.00004 inches for the highest precision tier
• Tool steel construction for hardness and dimensional stability
• 4 micro surface finish for accurate contact measurement
• NIST-traceable Certificate of Accuracy included with each unit
• 0.555 inch diameter, 2 inches long for standard pin gage handle compatibility

Compatibility

Designed as an OEM-style precision reference gage for use with standard pin gage handles and holders in quality control and calibration applications.

Installation Notes

Pin gages should be handled with clean, lint-free gloves or tissue to prevent oil and debris from affecting measurement accuracy. Store the gage in its protective case when not in use to prevent nicks or corrosion. Do not force the gage into a bore; light hand pressure only prevents damage to the gage and the workpiece. Calibration intervals should follow your facility quality management procedures.
