Value Collection SF043042 Precision Dowel Pin 5/16x2 in

Product Description

The VALUE COLLECTION SF043042 is a precision dowel pin manufactured from Grade 8 alloy steel to ASME B18.8.2 standards. It measures 5/16 inch in diameter and 2 inches in overall length, with a diameter tolerance of 0.0002 inches for tight, repeatable positioning. One end is beveled and one end is rounded, conforming to standard dowel pin geometry. Hardness is rated at 50-58 HRC, and the pin is rated for a breaking strength of 20,000 pounds in double shear. Machinists, tool and die makers, and assembly technicians install these pins to align fixtures, dies, jigs, and mating components in precision manufacturing applications.

This dowel pin is suited for use in precision alignment and locating applications across industrial, tooling, and machine shop environments. The Grade 8 alloy steel construction and tight diameter tolerance make it appropriate for high-load, tight-tolerance assemblies where repeatable positioning is critical. The ASME B18.8.2 standard ensures dimensional consistency for interchangeable use in existing setups. This is a single-unit package; minimum order quantity is 100 pieces.

Compatibility

Designed as a standard ASME B18.8.2 precision dowel pin for use in tooling, fixturing, and machine assembly applications requiring a 5/16-inch diameter locating pin with a 2-inch length.

Installation Notes

Precision dowel pins are typically pressed or driven into reamed holes by machinists or assembly technicians using an arbor press or mallet with a driving tool. Hole diameter and surface finish should be verified against the pin tolerance before installation to ensure proper interference or slip fit. Pins should not be hammered directly on the end face without a proper driver to avoid deformation. Always verify that mating components are properly supported and aligned before pressing the pin into place.
