Value Collection 34905 Pull Out Dowel Pin 3/8x2.25in Grade 8

Product Description

The VALUE COLLECTION 34905 is a standard pull out dowel pin designed for precision alignment and locating applications in machined assemblies. Manufactured from alloy steel at Material Grade 8, this pin measures 3/8 inch in diameter and 2.25 inches in overall length. It features one beveled end and one rounded end, making it easier to press into a reamed hole and pull out without damaging the bore. Hardness runs 50-58 HRC, giving the pin the wear resistance needed for repeated use in production fixtures, jigs, and tooling setups. Breaking strength is rated in double shear, the relevant load condition for most dowel pin installations.

This pin is suited for use in machine shops, production facilities, and maintenance environments where tight positional tolerances are required between mating components. The 3/8-inch diameter and 2.25-inch length make it a common choice for medium-duty fixturing, die sets, and precision assembly work. Machinists, tool and die makers, and millwrights install these pins in ground and reamed holes to maintain part alignment through repeated disassembly cycles. The pull out design supports easy removal without the need for a press in most applications.

Key Features

• Alloy Steel construction, Material Grade 8 for high strength and durability
• Hardness rated 50-58 HRC for wear resistance in repetitive use
• One beveled end and one rounded end for guided installation and clean removal
• Diameter tolerance of 0.0002 inches for precision fit in reamed holes
• Breaking strength rated in double shear
• Conforms to ASME B18.8.2 fastener standard

Compatibility

Designed as an OEM-style replacement or direct-fit dowel pin for precision alignment applications conforming to ASME B18.8.2, fitting standard reamed holes sized for a 3/8-inch nominal diameter pull out dowel pin.

Installation Notes

Installation is performed by machinists or maintenance technicians using a press or mallet into a ground, reamed hole sized to the appropriate tolerance for the pin diameter. De-energize and lock out all machinery before servicing any fixturing or assembly that uses dowel pins. Do not hammer pins into holes that have not been properly reamed to tolerance, as this can damage the hole or the pin. Use appropriate extraction tooling at the threaded or slotted pull out feature to remove the pin without galling the bore.
