Value Collection SF043059 Precision Dowel Pin 1/2 Alloy Steel

Product Description

The VALUE COLLECTION SF043059 is a precision dowel pin used to align, locate, and retain components in mechanical assemblies. Manufactured from alloy steel to Material Grade 8, this pin measures 0.5 inches in diameter and 2.25 inches in overall length. It meets ASME B18.8.2 dimensional standards and carries a Rockwell hardness of 50-58 HRC, making it suitable for high-load, tight-tolerance applications. The diameter is held to a tolerance of 0.0002 inches, ensuring consistent press-fit or slip-fit performance in precision-machined bores. End configuration is one beveled end and one rounded end. Breaking strength is rated at 51,000 pounds in double shear. Machinists, tool-and-die makers, and maintenance technicians are the typical installers.

This dowel pin is used in jig-and-fixture work, die sets, machine tool assemblies, and general industrial maintenance where repeatable, accurate part location is required. The Grade 8 alloy steel construction makes it appropriate for both static and dynamic load environments. It is well suited to applications in manufacturing, metalworking, and heavy equipment maintenance where ASME B18.8.2 compliance is specified. Sold individually, with a minimum order quantity of 10 pieces per order.

Key Features

• ASME B18.8.2 compliant precision dowel pin
• Alloy steel, Material Grade 8 for high hardness and strength
• Rockwell hardness 50-58 HRC for wear resistance in tight-tolerance bores
• Diameter tolerance of 0.0002 inches for consistent fit
• 51,000-pound double-shear breaking strength
• One beveled end and one rounded end for guided insertion

Compatibility

Designed as a standard precision dowel pin per ASME B18.8.2, suitable for use in any application requiring a 0.5-inch diameter dowel location pin in an ASME-conforming bore.

Installation Notes

Precision dowel pins are typically installed by machinists or maintenance technicians using an arbor press or dead-blow mallet, depending on fit class. Verify bore diameter and surface finish before installation to avoid galling or seizing. Pins should be driven squarely into the bore to prevent cocking or bore damage. Always de-burr and clean the receiving hole before pressing the pin into position.
