Value Collection SF043051 Precision Dowel Pin 3/8 X 2.5 in Grade 8

Product Description

The VALUE COLLECTION SF043051 is a precision dowel pin manufactured from alloy steel to ASME B18.8.2 standards. It measures 3/8 inch in diameter and 2.5 inches in overall length, with a diameter tolerance of 0.0002 inches for tight, repeatable location in machined assemblies. Hardness is rated at 50-58 HRC, and double-shear breaking strength is 28,700 pounds. One end is beveled for easy insertion; the other end is rounded. This pin is used by machinists, tool and die makers, and maintenance technicians to locate and align mating components with precision.

Precision dowel pins of this type are standard in jig and fixture construction, die sets, machine bases, and assembly tooling where consistent part location across repeated disassembly and reassembly cycles is required. The Grade 8 alloy steel construction and ASME B18.8.2 compliance make this pin appropriate for both production tooling and maintenance-replacement applications in industrial and commercial shop environments. It is sold individually with a minimum order quantity of 10 units.

Compatibility

Designed as an OEM-style replacement or new-installation precision dowel pin for use in machined fixtures, tooling, and mechanical assemblies requiring ASME B18.8.2 compliant locating pins with a 3/8 inch nominal diameter.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using an arbor press or hand press for press-fit applications. Ensure the receiving hole is reamed to the appropriate tolerance before installation. Never hammer directly on the pin end without a proper driving tool, as this can damage the precision surface finish and alter fit. De-energize and lock out all equipment before servicing any assembly that requires dowel pin removal or replacement.
