Value Collection 261232PR Dowel Pin 5/16x2 in Alloy Steel Gr8

Product Description

The VALUE COLLECTION 261232PR is a standard pull-out dowel pin machined from Grade 8 alloy steel to ASME B18.8.2 specifications. It measures 5/16 inch in diameter and 2 inches in overall length, with a diameter tolerance of 0.0002 inches for precise hole engagement. One end is rounded for guided insertion; the opposite end is threaded to allow extraction with a standard pull-out tool. This type of pin is used in fixture, jig, and machine assembly work where accurate part alignment and repeatable disassembly are required. Machinists, tool-and-die makers, and maintenance technicians are the primary installers.

Pull-out dowel pins are suited for applications where components must be accurately located relative to one another and later separated without damage to the mating parts. The threaded pull-out end eliminates the need for press-fit removal, reducing risk of bore damage during disassembly. This pin is appropriate for industrial machinery, tooling plates, and precision fixtures where ASME B18.8.2 compliance is specified.

Key Features

• ASME B18.8.2 standard for dimensional and tolerance compliance
• Grade 8 alloy steel construction for high shear and tensile strength
• 0.0002-inch diameter tolerance for tight, accurate bore fit
• Threaded end enables non-destructive pull-out extraction
• Rounded lead end guides pin into bore without scoring
• 5/16-inch diameter x 2-inch length suits common tooling and fixture applications

Compatibility

Designed as a standard pull-out dowel pin per ASME B18.8.2 for use in tooling plates, jigs, fixtures, and precision machinery assemblies requiring a 5/16-inch diameter dowel hole.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or mallet to seat the pin into a reamed, tolerance-matched bore. Always ream the receiving bore to the specified diameter tolerance before installation to ensure proper fit and alignment. To remove, thread an appropriate extraction tool into the threaded end and pull axially — do not pry or drive from the side. Verify bore and pin surfaces are clean and free of burrs before assembly.
