Vermont Gage 141128700 Class X Plus Pin Gage 0.287 in

Product Description

The VERMONT GAGE 141128700 is a Class X Plus precision pin gage used to verify bore diameters, hole sizes, and slot widths in tight-tolerance manufacturing and inspection work. It measures 0.287 inches in diameter and 2 inches in length, with a tolerance of +0.00004 inches, placing it in the highest common accuracy class for go/no-go and attribute gaging applications. Constructed from tool steel with a 4 micro-inch finish, it delivers the surface quality and dimensional stability required for reliable, repeatable measurement. Each unit ships with a Certificate of Accuracy with NIST traceability, making it suitable for use in documented quality systems.

This pin gage is used in machine shops, toolrooms, quality labs, and production inspection environments. It is suited for calibrating measuring equipment or for directly gaging parts where a 0.287-inch nominal diameter is the feature of interest. Typical users include machinists, quality technicians, and metrology personnel working to tight drawing tolerances in both job-shop and high-volume production settings. The compact 2-inch length makes it easy to handle in standard pin gage fixtures or by hand.

Key Features

• Class X Plus tolerance of +0.00004 inches for high-accuracy attribute gaging
• Tool steel construction for dimensional stability and wear resistance
• 4 micro-inch surface finish for consistent, low-friction contact
• Includes Certificate of Accuracy with NIST traceability for quality system documentation
• 0.287-inch diameter, 2-inch length — ready for direct use or fixture integration

Compatibility

Designed for use as a precision attribute gage in any application requiring a 0.287-inch nominal diameter pin, including calibration of measuring equipment and direct part gaging in machining and inspection environments.

Installation Notes

Pin gages should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Before use, verify the gage is clean and free of burrs or debris that could affect measurement accuracy. Store in the provided case when not in use to protect the finish and maintain NIST-traceable certification validity. No special tools are required for handheld use; consult your quality management system for calibration interval requirements.
