Vermont Gage 141122400 Class X Plus Pin Gage 0.224 in

Product Description

The VERMONT GAGE 141122400 is a Class X Plus precision pin gage used to verify hole diameters, check bore tolerances, and calibrate measuring equipment to tight dimensional standards. It measures 0.224 inches in diameter and 2 inches in length, machined from tool steel with a 4 micro-inch surface finish. The tolerance is held to +0.00004 inches, placing it in the Class X Plus accuracy tier. Each pin ships with a Certificate of Accuracy traceable to NIST. Quality control technicians, machinists, and calibration lab personnel use this gage in production and inspection environments where precise bore verification is required.

This pin gage is suited for direct gaging of machined parts, inspection of drilled or reamed holes, and calibration of measuring instruments such as bore gages and air gages. The 0.224-inch diameter makes it appropriate for small-bore applications common in precision machining, tooling, and quality assurance workflows across manufacturing and metalworking industries. It is equally at home on a shop floor or in a controlled metrology environment.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-accuracy dimensional inspection
• Tool steel construction for hardness and wear resistance under repeated use
• 4 micro-inch surface finish for consistent, low-friction gage contact
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• Compact 2-inch length suited for standard pin gage handles and manual inspection routines

Compatibility

Designed as a direct-use precision pin gage for verifying 0.224-inch nominal diameter bores and for calibration of measuring equipment requiring NIST-traceable reference standards.

Installation Notes

Pin gages are handled by quality technicians and calibration personnel rather than installed in a traditional sense. Store the pin in its protective case when not in use to prevent corrosion and surface damage. Clean the pin and the bore or instrument port with a lint-free cloth before use to prevent debris from affecting measurement accuracy. Do not force the pin into an undersized bore, as this can damage both the gage and the workpiece surface.
