Value Collection 34886 Dowel Pin 1/4x5/8 in Alloy Steel Gr8 25pk

Product Description

The VALUE COLLECTION 34886 is a standard pull out dowel pin manufactured from Grade 8 alloy steel and designed for precision locating and alignment applications in mechanical assemblies. The pin measures 1/4 inch in diameter and 0.625 inches in overall length, with a diameter tolerance of 0.0002 inches for tight, repeatable fits. Hardness is rated at C 50-58 on the Rockwell scale, providing strong resistance to wear and deformation under load. The pin features one beveled end and one rounded end, conforming to ASME B18.8.2, the recognized standard for dowel pins used in industrial and commercial applications. Machinists, tool and die makers, and maintenance technicians install these pins to align fixtures, jigs, and machine components.

This pin is suited for use in precision metalworking, tooling, and machine assembly environments where repeatable part location is critical. The pull out design allows for easier removal from blind holes compared to standard straight pins, making it practical for applications requiring frequent disassembly or maintenance access. Sold in a package quantity of 25, this SKU is appropriate for shop floor stocking or job-lot use where multiple installations are anticipated.

Key Features

• Grade 8 alloy steel construction with Rockwell hardness C 50-58 for durability under shear and compressive loads
• One beveled end and one rounded end per ASME B18.8.2 standard geometry
• Diameter tolerance of 0.0002 inches for precision locating fits
• Breaking strength measured in double shear configuration
• Pull out design facilitates removal from blind or close-tolerance holes
• Package of 25 pins for shop stocking convenience

Compatibility

Designed as an ASME B18.8.2 standard pull out dowel pin suitable for precision locating and alignment applications in metalworking fixtures, jigs, machine components, and tooling assemblies where a 1/4 inch diameter pin is specified.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or mallet with appropriate driving equipment to avoid deforming the pin ends. Ensure the receiving hole is reamed to the correct tolerance before pressing the pin into position. De-energize and lock out all equipment before servicing any assembly containing dowel pins. The pull out feature requires a threaded puller or extraction tool for removal — do not attempt to drive the pin out from the beveled end with a punch, as this may damage the hole or surrounding material.
