Value Collection SF043047 Precision Dowel Pin 3/8x1.5in Grade 8

Product Description

The VALUE COLLECTION SF043047 is a precision dowel pin used to align, locate, and retain components in mechanical assemblies. Machined from alloy steel to Grade 8 standards and hardened to 50-58 HRC, this pin provides reliable shear resistance and dimensional consistency in high-load applications. It measures 3/8 inch in diameter and 1-1/2 inches in overall length, with a diameter tolerance of 0.0002 inches for a precise fit. One end is beveled for easy insertion; the other end is rounded. Machinists, tool-and-die makers, and maintenance technicians install these pins in fixtures, jigs, molds, and precision assemblies where repeatable positioning is critical.

This dowel pin is suited for use in manufacturing fixtures, machine tool components, and structural assemblies requiring tight positional tolerances. The alloy steel construction and Grade 8 classification make it appropriate for moderate to heavy industrial service where hardness and breaking strength are primary concerns. A double-shear breaking strength of 28,700 pounds supports demanding load conditions. It conforms to ASME B18.8.2, the standard dimensional and tolerance specification for precision dowel pins in the United States.

Installation Notes

Precision dowel pins are typically pressed or driven into reamed holes by machinists or maintenance technicians using an arbor press or dead-blow mallet. Hole size and surface finish must be held to the appropriate tolerance class before installation to achieve the intended interference or transition fit. Always deburr and clean the mating bore before pressing the pin to avoid galling or dimensional damage. Follow applicable shop safety and machinery lockout procedures before inserting or removing pins in powered equipment.
