Value Collection 34897 Pull Out Dowel Pin 5/16 X 2 in Grade 8

Product Description

The VALUE COLLECTION 34897 is a standard pull out dowel pin designed for precise alignment and location of machine components in industrial and mechanical assemblies. Manufactured from alloy steel to Material Grade 8, this pin meets ASME B18.8.2 dimensional standards and carries a Rockwell C 50-58 hardness rating, making it suitable for demanding load applications. The pin measures 5/16 inch in diameter and 2 inches in overall length, with a diameter tolerance of 0.0002 inches for close-tolerance fits. End configuration is one beveled end and one rounded end, which aids in press-fit installation and pullout access. Machinists, toolmakers, and maintenance technicians working on jigs, fixtures, dies, and machinery frames are the primary installers.

This pull out dowel pin is used in applications where components must be repeatedly disassembled and reassembled to exact alignment. The beveled end allows for guided entry into a reamed or drilled hole, while the rounded end accepts a slide hammer or puller for controlled removal without damaging the mating bore. Typical installation scenarios include fixture plates, press tooling, machine bases, and production equipment where positional repeatability is critical. The ASME B18.8.2 compliance makes this pin appropriate for production and maintenance environments governed by standard fastener specifications.

Key Features

• Alloy steel construction, Material Grade 8, for high strength and wear resistance
• Rockwell C 50-58 hardness rating supports use in high-load, high-cycle applications
• ASME B18.8.2 compliant for standardized dimensional interchangeability
• One beveled end and one rounded end for guided installation and tool-assisted pullout
• Diameter tolerance of 0.0002 inches ensures close-tolerance bore fitment
• Double shear configuration for breaking strength measurement

Compatibility

Designed as a standard-geometry pull out dowel pin conforming to ASME B18.8.2, suitable for use in any application requiring a 5/16 inch diameter, 2 inch length pull out dowel pin in that fastener class.

Installation Notes

Installation is performed by machinists or maintenance technicians using a press or mallet against the beveled end to seat the pin into a precision-reamed hole. Ensure the mating bore is clean, deburred, and sized to the appropriate tolerance before installation. Power down and lock out all machinery before installing or removing dowel pins in active equipment. Use a proper slide hammer or pin puller on the rounded end for removal to avoid bore damage.
