Value Collection SF043050 Precision Dowel Pin 3/8 Alloy Steel

Product Description

The VALUE COLLECTION SF043050 is a precision dowel pin used to align, locate, and anchor mating components in mechanical assemblies. Manufactured from alloy steel at Grade 8, this pin measures 3/8 inch in diameter and 2.25 inches in overall length. It meets ASME B18.8.2 dimensional standards and carries a hardness rating of 50-58 HRC, making it suited for high-load, tight-tolerance applications. One end is beveled for guided insertion; the other end is rounded. The diameter tolerance is held to 0.0002 inches, supporting precision fit in close-tolerance bored holes. Licensed machinists, tool-and-die technicians, and maintenance mechanics are the primary installers.

This dowel pin is used in jigs, fixtures, molds, dies, and machine bases where repeatable part alignment is required. It is appropriate for both original equipment manufacturing and maintenance-and-repair operations across industrial, automotive, and aerospace tooling contexts. The pin is sold individually but must be ordered in multiples of 10 to meet the minimum order quantity requirement.

• Meets ASME B18.8.2 fastener standard
• Double-shear breaking strength of 28,700 pounds

Compatibility

Designed as an OEM-style precision locating pin for mechanical assemblies requiring a 3/8-inch diameter dowel conforming to ASME B18.8.2.

Installation Notes

Installation is performed by machinists or maintenance mechanics using a press or mallet with a proper driver; never strike the pin surface directly with a steel hammer. Ensure the receiving bore is clean, within specified tolerance, and free of burrs before pressing the pin. Degrease mating surfaces as required by the assembly specification. Removal should be performed with a pin press or punch sized appropriately to avoid bore damage.
