Value Collection 261271PR Pull Out Dowel Pin 3/8x1-3/4 Grade 8

Product Description

The VALUE COLLECTION 261271PR is a standard pull out dowel pin designed for precision alignment and locating applications in mechanical assemblies. Machined from Grade 8 alloy steel, this pin measures 3/8 inch in diameter and 1-3/4 inches in overall length. It features one rounded end and one threaded end, which allows the pin to be extracted using a standard puller tool without damaging the mating bore. The diameter is held to a tight tolerance of plus or minus 0.0002 inches, making it suitable for close-tolerance fit applications. Machinists, tool and die technicians, and maintenance mechanics install this type of pin where precise, repeatable component alignment is required.

Pull out dowel pins are used in fixture plates, jigs, molds, machine bases, and industrial equipment where components must be accurately registered and later disassembled for service or adjustment. The threaded end allows a puller or slide hammer to engage the pin directly, reducing the risk of bore damage during removal. This pin is appropriate for both original assembly and replacement use in light to heavy industrial environments where alloy steel strength and dimensional precision are required.

Key Features

• One rounded end and one threaded end for tool-assisted extraction
• Grade 8 alloy steel construction for high shear strength and wear resistance
• Diameter tolerance of 0.0002 inches for close-tolerance locating fits
• Manufactured to ASME B18.8.2 standard for dimensional conformance
• 3/8 inch diameter by 1-3/4 inch length for common alignment applications

Compatibility

Designed as a standard-dimension replacement or original-fit pull out dowel pin for jigs, fixtures, molds, and industrial machine assemblies requiring a 3/8 inch diameter locating pin conforming to ASME B18.8.2.

Installation Notes

Installation and removal are typically performed by machinists or maintenance mechanics using an arbor press for seating and a threaded puller or slide hammer for extraction via the threaded end. Always ensure the receiving bore is clean, dimensionally correct, and free of burrs before driving the pin. Power down and de-energize any associated equipment before servicing components that contain dowel pins. Follow applicable machinery safety standards and shop practices when working with press-fit components.
