Value Collection 40073 Pull Out Dowel Pin 1/4x1 in Grade 8

Product Description

The VALUE COLLECTION 40073 is a standard pull out dowel pin designed for precision alignment and locating applications in mechanical assemblies. Manufactured from Grade 8 alloy steel with a bright uncoated finish, this pin meets ASME B18.8.2 dimensional standards. It measures 0.25 inches in diameter and 1 inch in overall length, with a diameter tolerance of 0.0002 inches for tight, repeatable fits. One end is beveled for easy insertion and the other is rounded to facilitate pull-out removal. Single shear strength is rated at 7,360 pounds and double shear strength at 14,720 pounds, making it suitable for demanding load-bearing alignment tasks. Machinists, tool and die makers, and maintenance technicians install this type of pin in fixtures, jigs, and machine components.

This dowel pin is used in industrial and manufacturing environments where accurate part-to-part alignment is required. Typical applications include fixture plates, mold tooling, press components, and general machine assembly where precise hole-to-hole registration must be maintained across repeated assembly and disassembly cycles. The pull-out configuration allows removal without a press in applications where access permits. Sold in a package quantity of 25 pins per pack.

Compatibility

Designed as an OEM-style replacement or direct-use component for applications requiring a 0.25 inch diameter by 1 inch length standard pull out dowel pin conforming to ASME B18.8.2.

Installation Notes

Dowel pins of this type are typically installed by machinists or maintenance technicians using a press or mallet, depending on hole tolerance and fit class. Ensure the receiving bore is clean, deburred, and dimensionally verified before installation. The beveled end should be oriented toward the entry side of the bore. When installing in hardened components, confirm bore hardness and surface finish are within specification to avoid galling or seizing during assembly.
