Vermont Gage 141268800 Class X Minus Pin Gage 0.688 in

Product Description

The VERMONT GAGE 141268800 is a Class X Minus precision pin gage used to verify bore diameters, hole tolerances, and feature dimensions in manufactured parts and calibration setups. It measures 0.688 inches in diameter with a tight tolerance of -0.00004 inches, making it suitable for high-accuracy inspection work. The gage body is 2 inches long and manufactured from tool steel with a 4 micro finish surface. A Certificate of Accuracy with NIST traceability is included, supporting quality assurance documentation requirements in shop and lab environments. Dimensional inspectors, machinists, and quality technicians use this type of gage in both production and calibration settings.

This pin gage is designed for direct part gaging and for calibrating measuring equipment where confirmed bore or hole dimensions are required. The Class X Minus designation indicates the gage is undersized within Class X tolerance limits, which allows it to function as a go-type reference in close-tolerance inspection. It is appropriate for use in tool rooms, machine shops, and quality labs handling precision components. The 4 micro finish reduces wear and ensures consistent contact across repeated uses.

Key Features

• 0.688 inch nominal diameter with -0.00004 inch tolerance for high-precision inspection
• Class X Minus designation for close-tolerance go-gage applications
• Tool steel construction with 4 micro surface finish for durability and accuracy
• 2 inch length provides stable handling during manual inspection
• Includes Certificate of Accuracy with NIST traceability for documentation and audit compliance
• Suitable for direct part gaging and calibration of measuring equipment

Compatibility

Designed for use as a precision reference gage in applications requiring calibration of measuring equipment or direct gaging of parts to a 0.688 inch nominal diameter specification.

Installation Notes

Pin gages are handled and used by dimensional inspectors and quality technicians. Clean the gage and the feature being measured before use to prevent debris from affecting readings. Store in a protective case when not in use to avoid surface damage that could affect tolerance accuracy. Do not force the gage into an undersized feature, as this can damage both the gage and the part.
