Value Collection SF043046 Precision Dowel Pin 3/8 X 1-1/4 in Grade 8

Product Description

The VALUE COLLECTION SF043046 is a precision dowel pin designed for accurate alignment and location of machined components in manufacturing, tooling, and assembly applications. Machined from alloy steel to Material Grade 8, this pin measures 0.375 inches in diameter and 1.25 inches in overall length, with a diameter tolerance of 0.0002 inches for tight, repeatable fits. The pin carries a hardness rating of 50-58 HRC and meets ASME B18.8.2 standards. It is typically installed by machinists, tool-and-die makers, and maintenance technicians working with jigs, fixtures, dies, and precision assemblies.

This dowel pin is suited for use in industrial manufacturing environments where precise component alignment is required. The combination of alloy steel construction, Grade 8 material rating, and ASME B18.8.2 compliance makes it appropriate for high-load, close-tolerance applications in metalworking, fixture building, and machine assembly. One end is beveled and one end is rounded, allowing for guided insertion into reamed or press-fit holes in mating components.

Key Features

• Diameter tolerance of 0.0002 inches for precise, repeatable alignment
• 50-58 HRC hardness for wear resistance in high-cycle applications
• Breaking strength of 28,700 pounds (double shear) for high-load fitments
• One beveled end and one rounded end for controlled insertion and seating
• Meets ASME B18.8.2 fastener standard for dimensional consistency
• Alloy steel, Grade 8 material for strength and durability

Compatibility

Designed as an OEM-style precision dowel pin for use in standard 3/8-inch reamed or press-fit holes conforming to ASME B18.8.2 dimensional requirements in industrial fixtures, dies, and machined assemblies.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a drill press, arbor press, or pin driver. Receiving holes should be reamed to the appropriate tolerance class before installation to ensure proper fit. De-energize and lock out all equipment before installing or removing dowel pins from active assemblies. Do not hammer pins into undersized holes, as this may compromise the tolerance fit or damage mating components.
