Value Collection 251255PR Oversized Dowel Pin 3/8x1 in Alloy

Product Description

The VALUE COLLECTION 251255PR is a military specification oversized dowel pin designed for precision alignment and fastening applications in industrial and mechanical assemblies. Manufactured from alloy steel with a hardness rating of 50-58 HRC, this pin delivers the wear resistance and shear strength required in demanding environments. It measures 3/8 inch in diameter and 1 inch in overall length, with a diameter tolerance of 0.0010 decimal inches for tight, controlled fits. With a double-shear breaking strength of 28,700 pounds, it is suited for high-load alignment tasks. Licensed technicians and machinists working with precision assemblies will find this pin meets ASME B18.8.2 standards.

This oversized dowel pin is intended for use in precision mechanical assemblies, tooling fixtures, jigs, and equipment requiring tight positional tolerances. The oversized designation makes it appropriate for worn or reamed holes where a standard pin would no longer provide adequate interference fit. It is commonly installed in manufacturing, maintenance, and repair operations across industrial and heavy-equipment settings where reliable component alignment is critical.

Key Features

• Alloy steel construction with 50-58 HRC hardness for wear resistance and durability
• Double-shear breaking strength of 28,700 pounds for high-load applications
• Diameter tolerance of 0.0010 decimal inches for precision fit in reamed or oversized holes
• One beveled end and one rounded end for guided insertion and secure seating
• Meets ASME B18.8.2 fastener standard for military specification oversized dowel pins

Compatibility

Designed as an OEM-style replacement or upgrade for applications requiring a military specification oversized dowel pin per ASME B18.8.2, with a 3/8 inch diameter and 1 inch overall length.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a pin press or arbor press. Ensure the receiving hole is clean, properly reamed to the correct oversized tolerance, and free of burrs before pressing the pin into place. Deburr and clean mating components before assembly to avoid galling or misalignment. Always follow applicable safety procedures and equipment manufacturer guidelines when working with precision fasteners under load.
