Value Collection 261235PR Dowel Pin 5/16 X 2.25 in Grade 8

Product Description

The VALUE COLLECTION 261235PR is a standard pull out dowel pin designed for precise alignment and positioning applications in mechanical assemblies. Manufactured from Grade 8 alloy steel, this pin delivers the strength and hardness required for demanding industrial and machining environments. It measures 5/16 inches in diameter with an overall length of 2.25 inches. One end is rounded for easy insertion into a bored hole, while the opposite end is threaded to accept a pull-out tool, allowing controlled removal without damage to the workpiece. The pin conforms to ASME B18.8.2 tolerances, with a diameter tolerance of 0.0002 inches for precise hole fitment. Licensed machinists, millwrights, and tool-and-die technicians are the primary installers.

This dowel pin is suited for use in jigs, fixtures, molds, dies, and machined component assemblies where repeatable alignment between mating parts is critical. The pull-out thread feature makes it practical in blind-hole applications where a standard pin would be difficult to extract. It is appropriate for both production and maintenance settings across general manufacturing, toolroom, and precision fabrication environments.

Key Features

• Pull-out threaded end allows controlled extraction from blind holes without damaging the bore
• Rounded drive end for guided insertion into close-tolerance holes
• Grade 8 alloy steel construction for high shear strength and hardness
• Diameter tolerance of 0.0002 inches for accurate slip or press fit applications
• Conforms to ASME B18.8.2 fastener standard

Compatibility

Designed as an OEM-style replacement or standard component for mechanical assemblies, jigs, fixtures, and tooling that require ASME B18.8.2 compliant dowel pins in a 5/16-inch diameter pull-out configuration.

Installation Notes

Installation is typically performed by machinists or millwrights using a press or mallet and appropriate alignment tooling. Always de-energize and lock out any equipment before servicing assemblies that contain dowel pins. Use the threaded pull-out end with a properly sized extraction tool rated for the pin diameter to remove the pin cleanly. Inspect the receiving bore for size and finish compliance with ASME B18.8.2 tolerances before installation.
