Vermont Gage 141103100 Class X Plus Pin Gage 0.031 in

Product Description

The VERMONT GAGE 141103100 is a Class X Plus pin gage designed for high-precision measurement work in metrology, quality control, and production environments. Machined from tool steel with a 4 micro finish, it measures 0.031 inches in diameter with a tolerance of +0.00004 inches, placing it firmly in the Class X Plus accuracy range. At 2 inches in length, the gage is sized for direct part gaging and calibration of measuring equipment. Each unit ships with a Certificate of Accuracy with NIST traceability, making it suitable for use in documented quality systems and ISO-compliant inspection processes. Machinists, quality technicians, and calibration lab personnel are the primary users of this tool.

This pin gage is used wherever tight-tolerance hole gaging or instrument calibration is required. Typical applications include verifying bore diameters, checking drill and punch clearances, and calibrating measuring instruments to traceable standards. It is appropriate for both shop-floor inspection and controlled calibration lab environments. The 0.031-inch diameter makes it well suited for small-bore inspection common in precision machining, medical device manufacturing, aerospace component inspection, and similar industries where dimensional accuracy is critical.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-accuracy measurement
• Tool steel construction for durability and dimensional stability
• 4 micro surface finish for consistent, repeatable gage contact
• Includes Certificate of Accuracy with NIST traceability
• 0.031 inches diameter at 2 inches length for small-bore inspection tasks

Compatibility

Designed as a Class X Plus go/no-go and direct measurement pin gage for use with standard pin gage handles and sets requiring 0.031-inch diameter members in calibration and inspection applications.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion and contamination of the gage surface. Store in the provided case or a protective holder when not in use to maintain the calibrated surface finish. Verify the gage and the part or instrument being measured are at the same temperature before use to avoid thermal expansion errors. Periodic recalibration against NIST-traceable standards is recommended per your facility quality plan.
