Jergens 31610 Pull Out Dowel Pin 5/16 X 1-1/4 Inch Alloy Steel

Product Description

The JERGENS 31610 is a pull out dowel pin machined from alloy steel for use in precision alignment and locating applications. It measures 5/16 inch in diameter with an overall length of 1.25 inches and features a threaded end that allows extraction with a standard puller or threaded rod, making removal straightforward even in tight or blind-hole installations. The close diameter tolerance of -0.0001 to 0.0001 inch ensures consistent, repeatable fit in hardened tooling plates, fixtures, and machine components. This pin meets ASME B18.8.2 dimensional standards and is sold individually.

Pull out dowel pins like the 31610 are commonly used in fixture building, tool and die work, and precision machine assembly where repeatable part location is required. The threaded extraction feature makes this pin well suited to applications where the pin must be removed frequently or where a press-fit pin would be impractical to drive out. Machinists, tool makers, and maintenance technicians working on production tooling and jigs will find this pin appropriate for both new builds and field repairs.

Key Features

• Threaded end design allows extraction without damaging the pin or host bore
• Alloy steel construction provides strength suitable for precision tooling applications
• Diameter tolerance of -0.0001 to 0.0001 inch for tight, repeatable locating fits
• Conforms to ASME B18.8.2 dimensional standard
• 5/16 inch diameter by 1.25 inches overall length

Compatibility

Designed as an OEM-style replacement or standard component for use in fixtures, jigs, tooling plates, and precision machine assemblies that require a 5/16 inch pull out dowel pin conforming to ASME B18.8.2.

Installation Notes

Installation and removal are typically performed by a machinist or tool and die technician. Ensure the mating bore is clean, within tolerance, and properly deburred before pressing the pin into position. To extract, thread a compatible puller or bolt into the threaded end and apply steady, controlled force to avoid bore damage. Consult applicable fixture or assembly drawings for proper pin engagement depth before installation.
