Vermont Gage 141143350 Class X Plus Pin Gage 0.4335 in

Product Description

The VERMONT GAGE 141143350 is a Class X Plus precision pin gage designed for direct part gaging and calibration of measuring equipment. Machined from tool steel with a 4 microinch surface finish, it delivers the tight tolerances required for Class X Plus classification, with a tolerance of +0.00004 inches on a 0.4335-inch nominal diameter. At 2 inches in length, it fits standard pin gage handles and accessories used throughout metrology labs and production floor inspection stations. Each unit ships with a Certificate of Accuracy traceable to NIST standards, making it suitable for ISO-compliant quality systems and audit documentation requirements.

This pin gage is used in manufacturing, machining, and quality control environments where precise hole diameter verification is required. Typical applications include checking bored, drilled, or reamed holes in metal, plastic, or composite workpieces during in-process or final inspection. Metrology technicians, quality engineers, and machining professionals use Class X Plus gages when the tightest dimensional verification is needed, particularly on close-tolerance fits such as bearing bores, bushings, and precision assembly features.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-precision dimensional verification
• 0.4335-inch nominal diameter for direct hole gaging
• Tool steel construction for durability and dimensional stability
• 4 microinch surface finish for consistent, repeatable contact measurement
• Includes Certificate of Accuracy with NIST traceability for calibration records
• 2-inch length compatible with standard pin gage handles and accessories

Compatibility

Designed as a standard Class X Plus pin gage for use with conventional pin gage handles and accessories used in general metrology and production inspection applications.

Installation Notes

Pin gages should be inserted by hand without forced pressure to avoid bore or gage damage. Clean and dry both the gage and the workpiece bore before use to ensure accurate measurement. Store the gage in its protective sleeve or case when not in use to prevent surface damage that could affect calibration. Periodic re-calibration against NIST-traceable standards is recommended in accordance with your facility quality program.
