Vermont Gage 141107300 Class X Plus Pin Gage 0.073 in

Product Description

The VERMONT GAGE 141107300 is a Class X Plus pin gage designed for high-precision dimensional inspection. It measures 0.073 inches in diameter and 2 inches in length, manufactured from tool steel with a 4 micro-inch surface finish. Class X Plus represents one of the tightest tolerance grades available in pin gage sets, with a unilateral tolerance of +0.00004 inches. Each gage ships with a Certificate of Accuracy traceable to NIST standards, confirming it meets the stated tolerance at the time of manufacture. Metrology technicians, quality control inspectors, and precision machinists rely on this type of gage for direct part inspection and calibration of measuring equipment.

This pin gage is used in manufacturing and metrology environments where precise hole diameter verification is required. It is suited for checking drilled, reamed, or bored holes in both production and inspection settings. The 0.073-inch diameter makes it appropriate for small-bore applications common in precision machining, tooling, and instrumentation work. It functions as a go or no-go reference when used in conjunction with a complete pin gage set, and serves as a direct reference standard for calibrating other measuring instruments. Typical users include QC labs, machine shops, and tool rooms operating under AS9100, ISO 9001, or similar quality management systems.

Key Features

• Class X Plus tolerance grade: +0.00004 inches unilateral for high-accuracy inspection
• Tool steel construction provides hardness and wear resistance suited for repeated use
• 4 micro-inch surface finish supports consistent, repeatable gage contact
• Includes Certificate of Accuracy with NIST traceability for quality documentation requirements
• 0.073 inch diameter covers small-bore inspection applications
• Compact 2 inch length allows use in confined inspection setups

Compatibility

Designed as a direct-use precision reference gage for calibration of measuring equipment or for gaging parts directly in any inspection or metrology application requiring a 0.073 inch diameter Class X Plus pin gage.

Installation Notes

Pin gages of this tolerance class should be handled with clean, lint-free gloves to prevent contamination from skin oils that can affect measurement accuracy. Store the gage in its protective sleeve or case when not in use to prevent damage to the ground surface finish. Allow the gage and the workpiece to reach the same ambient temperature before use, as thermal expansion can affect measurements at this tolerance level. Periodic recalibration against a certified NIST-traceable reference is recommended to maintain accuracy documentation.
