Value Collection 241319PR Precision Dowel Pin 7/16x3 in Grade 8

Product Description

The VALUE COLLECTION 241319PR is a precision dowel pin designed for tight-tolerance alignment and locating applications in machined assemblies. Manufactured from Grade 8 alloy steel with a hardness of 50-58 HRC, this pin delivers the shear strength and dimensional consistency required for demanding production and maintenance environments. It measures 7/16 inches in diameter and 3 inches in overall length, with a diameter tolerance of 0.0002 inches. One end is beveled and one end is rounded, following standard ASME B18.8.2 geometry. Machinists, tool and die technicians, and maintenance professionals install these pins to maintain precise part registration in fixtures, dies, and assemblies.

This pin is suited for use in precision fixtures, jigs, molds, and mechanical assemblies where controlled fit and repeatable positioning are required. The Grade 8 alloy steel construction and 50-58 HRC hardness make it appropriate for high-load, high-cycle applications in industrial and manufacturing settings. It conforms to ASME B18.8.2, the standard governing inch-series dowel pins. Sold individually per package; minimum order quantity is 10 units.

Key Features

• One beveled end and one rounded end per ASME B18.8.2 standard geometry
• Double-shear breaking strength of 39,100 pounds
• Conforms to ASME B18.8.2 for dimensional compliance
• Consistent geometry supports repeatable use in production fixtures and dies

Compatibility

Designed as a standard ASME B18.8.2 precision dowel pin for use in inch-series machined assemblies requiring 7/16-inch diameter locating pins.

Installation Notes

Precision dowel pins are typically pressed or driven into reamed holes by machinists or maintenance technicians using an arbor press or similar controlled-force tool. Holes should be finish-reamed to the appropriate tolerance class before installation to ensure proper fit. Do not hammer pins directly without a driver or press plate, as this can damage the end geometry and affect alignment accuracy. Confirm the assembly is fully de-energized and secured before pin installation or removal.
