Value Collection 251124PR Mil-spec Oversized Dowel Pin

Product Description

The VALUE COLLECTION 251124PR is a military specification oversized dowel pin designed for precision alignment and fastening applications in industrial and mechanical assemblies. Manufactured from alloy steel, this pin measures 3/16 inches in diameter and 5/8 inches in overall length. It carries a hardness rating of 50-58 HRC, providing strong resistance to wear and deformation under load. One end is beveled and one end is rounded, following standard mil-spec geometry. The pin meets ASME B18.8.2 standards and is rated for a breaking strength of 7,200 pounds in double shear. Machinists, tool and die makers, and maintenance mechanics working with precision-fit assemblies are the typical installers.

This oversized dowel pin is suited for applications where standard-tolerance pins cannot maintain the required fit due to worn or reamed holes that have gone slightly beyond nominal diameter. The oversized diameter tolerance of 0.0010 inches allows for a controlled interference or transition fit in precision bores. Common use cases include jig and fixture alignment, die sets, machine tool components, and other close-tolerance mechanical assemblies in both production and MRO environments. The mil-spec designation confirms the pin meets stringent dimensional and material requirements for demanding industrial and defense-related applications.

Key Features

• Alloy steel construction with 50-58 HRC hardness for wear resistance and shear strength
• Military specification oversized design per ASME B18.8.2 for controlled-fit replacement applications
• Rated breaking strength of 7,200 pounds in double shear
• Diameter tolerance of 0.0010 inches for precision bore fitment
• One beveled end and one rounded end for guided installation into bored holes

Compatibility

Designed as an OEM-style replacement or upgrade dowel pin for precision mechanical assemblies requiring an oversized mil-spec pin per ASME B18.8.2 in a 3/16-inch diameter bore.

Installation Notes

Installation is typically performed by machinists or maintenance mechanics using an arbor press or pin driver to seat the pin without damage to the bore or pin end. Power to any associated machine or assembly must be locked out and tagged out before pin removal or installation per standard LOTO procedures. Do not use an impact hammer directly on the pin face without a proper driver or drift to avoid deforming the end geometry. Verify bore diameter and surface finish before installation to ensure the oversized tolerance produces the intended fit class.
