Value Collection MP34903 Dowel Pin 3/8 X 1.5 in Alloy Steel Gr8

Product Description

The VALUE COLLECTION MP34903 is a standard pull out dowel pin designed for precise alignment and location of mating components in mechanical assemblies. Machined from alloy steel to Material Grade 8, this pin measures 3/8 inch in diameter and 1.5 inches in overall length, with a tight diameter tolerance of 0.0002 inches that ensures accurate fit in reamed holes. Hardness is rated C 50-58 on the Rockwell scale, providing strong resistance to wear and deformation under load. The pin conforms to ASME B18.8.2 and features one beveled end and one rounded end, supporting guided insertion and a defined pull-out reference surface. Sold in a package quantity of 10.

This dowel pin is suited for use in tooling, fixturing, jigs, dies, and general mechanical assemblies where repeatable component alignment is required. The pull out style end configuration makes retrieval straightforward during disassembly, which is particularly useful in maintenance-intensive or frequently serviced fixtures. Typical installers include machinists, tool and die makers, maintenance mechanics, and industrial assembly technicians working in manufacturing, fabrication, or repair environments.

Key Features

• Diameter tolerance of 0.0002 inches for precise fit in reamed holes
• One beveled end and one rounded end per ASME B18.8.2 pull out pin standard
• Double shear breaking strength measurement method
• Conforms to ASME B18.8.2 fastener standard

Compatibility

Designed as an ASME B18.8.2-compliant standard pull out dowel pin suitable for use in any application requiring a 3/8 inch diameter alignment pin in alloy steel Grade 8.

Installation Notes

Installation is performed by machinists or maintenance mechanics using a press or mallet into a properly reamed and deburred hole sized to the pin diameter tolerance. Ensure mating holes are clean and free of debris before pressing the pin to avoid galling or dimensional damage. Pins should be removed with a pull-out tool or pin press applied axially to avoid bending. Consult applicable assembly drawings and torque or fit specifications before installation.
