Value Collection SF043031 Dowel Pin 1/4x1 Alloy Steel Gr8

Product Description

The VALUE COLLECTION SF043031 is a precision dowel pin designed for accurate alignment and positioning in mechanical assemblies. Manufactured from Grade 8 alloy steel, this pin measures 1/4 inch in diameter and 1 inch in overall length. It meets ASME B18.8.2 standards and carries a hardness rating of 50-58 HRC, making it well-suited for demanding load and wear conditions. One end is beveled for easy insertion and one end is rounded. The pin delivers a diameter tolerance of 0.0002 inches, supporting tight-fit applications where precision alignment is critical. Machinists, tool-and-die technicians, and mechanical assemblers typically install this component.

This dowel pin is used in jigs, fixtures, dies, and precision mechanical assemblies where repeatable part location is required. Its alloy steel construction and Grade 8 designation make it appropriate for both light production and heavy-duty industrial applications. The pin is sold individually but is subject to a minimum order quantity of 100 pieces, making it practical for shop stock or production-quantity procurement. It is appropriate for use in machine shops, manufacturing facilities, and maintenance environments where ASME B18.8.2-compliant fasteners are specified.

Compatibility

Designed as an OEM-style precision alignment component for use in jigs, fixtures, dies, and mechanical assemblies requiring ASME B18.8.2-compliant dowel pins with a 1/4-inch diameter.

Installation Notes

Precision dowel pins are typically pressed or driven into reamed holes by machinists or mechanical assemblers using an arbor press or hammer and punch. Ensure the receiving hole is reamed to the correct tolerance before installation to avoid damaging the pin or bore. De-energize and lock out any machinery before installing or removing dowel pins in active assemblies. Follow applicable facility safety and machinery standards during installation.
