Vermont Gage 141103900 Class X Plus Pin Gage 0.039 in

Product Description

The VERMONT GAGE 141103900 is a Class X Plus precision pin gage manufactured from tool steel for dimensional measurement and inspection work. At 0.039 inches in diameter and 2 inches in length, it is used to verify bore sizes, slot widths, and hole diameters to tight tolerances. The Class X Plus designation indicates a tolerance of +0.00004 inches, placing it among the highest accuracy grades available for go/no-go and calibration applications. Each gage ships with a Certificate of Accuracy traceable to NIST standards, supporting quality management and documentation requirements in precision manufacturing environments.

This pin gage is suited for calibration of measuring equipment and for direct part inspection on the production floor, in metrology labs, or in tool rooms. Machinists, quality technicians, and calibration specialists use Class X Plus gages when measurement uncertainty must be minimized. The 4 micro finish reduces surface variation that could affect readings. Applications include checking drilled, reamed, or broached holes in metal, plastic, and composite workpieces where dimensional conformance is critical.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-accuracy dimensional inspection
• Tool steel construction for durability and resistance to wear during repeated use
• 4 micro surface finish minimizes measurement variation caused by surface irregularities
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• Compact 2 inch length suits bench inspection and portable field use

Compatibility

Designed as a direct-use Class X Plus pin gage for calibration of measuring equipment or for gaging parts directly, consistent with standard go/no-go inspection practices in precision machining and quality control environments.

Installation Notes

Pin gages are handled by quality technicians and calibration personnel, not typically installed in a mechanical system. Store the gage in its protective case when not in use to prevent corrosion and surface damage. Clean the gage and the feature being measured before use to avoid false readings caused by debris or oil film. Do not force the gage into a hole; insertion should be smooth and free of lateral pressure to protect the gage surface and preserve its tolerance class.
