Value Collection EH-40101 Dowel Pin 3/8x2-1/4 Alloy Steel Gr8

Product Description

The VALUE COLLECTION EH-40101 is a standard pull out dowel pin designed for precision alignment and fastening applications in industrial and mechanical assemblies. Manufactured from Grade 8 alloy steel with a black luster finish, this pin measures 3/8 inch in diameter and 2-1/4 inches in overall length. It delivers a single shear strength of 16,550 pounds and a double shear strength of 33,100 pounds. The tight diameter tolerance of 0.0002 inches ensures consistent, reliable fit in precision-drilled holes. Machinists, maintenance technicians, and assembly professionals install this pin where repeatable positioning and high load capacity are required.

This dowel pin is suited for use in machine tool fixtures, jigs, dies, and general mechanical assemblies where accurate part alignment is critical. The pull out design allows for easier removal from blind holes compared to standard press-fit dowels. Sold in a package quantity of 25, it is appropriate for production environments and shop inventory. The black luster finish provides a degree of surface protection. Applications span light manufacturing, fabrication shops, and maintenance repair operations.

Key Features

• Grade 8 alloy steel construction provides high shear strength and wear resistance
• Single shear strength of 16,550 pounds and double shear strength of 33,100 pounds
• Diameter tolerance of 0.0002 inches for precision fit in close-tolerance holes

• Black luster finish for surface protection and identification

Compatibility

Designed as an OEM-style replacement or stock component for standard 3/8 inch precision-drilled alignment applications conforming to ASME B18.8.2 specifications.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or mallet and appropriate alignment tooling. Ensure the receiving hole is drilled and reamed to the correct diameter and depth before installation. De-energize and lock out all machinery before servicing any assembly containing dowel pins. The pull out feature requires a tapped hole or pull out groove at the bottom of the bore to allow removal with a slide hammer or extractor tool.
