Value Collection 251085PR Oversized Dowel Pin 1/8x3/8 in

Product Description

The VALUE COLLECTION 251085PR is a military specification oversized dowel pin designed for precise alignment and fastening applications in mechanical assemblies. Made from alloy steel with a hardness rating of 50-58 HRC, this pin delivers the wear resistance and shear strength required in demanding industrial and defense-grade applications. At 1/8 inch in diameter and 3/8 inch in overall length, it meets ASME B18.8.2 standards and is rated at 3,200 pounds breaking strength measured in double shear. Machinists, maintenance technicians, and assembly professionals install this type of pin where tight positional tolerances and repeatable alignment are critical.

This oversized dowel pin is suited for use in precision jigs, fixtures, machine frames, and structural assemblies requiring military-spec fastener compliance. The oversized diameter tolerance of 0.0010 inches ensures a controlled press or interference fit in bored holes, making it appropriate for both original equipment manufacturing and field replacement in applications subject to high cyclic loading or vibration. Its compact 1/8 x 3/8 inch profile fits confined spaces where standard-length pins are not appropriate.

Key Features

• Alloy steel construction with 50-58 HRC hardness for superior wear and shear resistance
• 3,200 pounds double shear breaking strength meets high-load alignment demands
• ASME B18.8.2 compliant military specification for standardized fitment
• Oversized diameter tolerance of 0.0010 inches for controlled interference fits
• End configuration: one beveled end and one rounded end for guided installation
• Compact 1/8 inch diameter by 3/8 inch length fits tight clearance applications

Compatibility

Designed as an OEM-style replacement or original-fit fastener for mechanical assemblies requiring ASME B18.8.2 military specification oversized dowel pins in 1/8 inch diameter bores.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using an arbor press or pin driver. Always ensure the receiving bore is properly sized and deburred before pressing the pin to avoid galling the alloy steel surface. Power down and de-energize any equipment before servicing assemblies that contain dowel pins under load. Follow applicable facility safety and torque procedures as governed by your engineering specifications.
