Value Collection 251337PR Mil-spec Oversized Dowel Pin 1/2x2 in

Product Description

The VALUE COLLECTION 251337PR is a military specification oversized dowel pin designed for precision alignment and fastening applications in demanding industrial and mechanical assemblies. Manufactured from alloy steel with a hardness rating of 50-58 HRC, this pin delivers the strength and wear resistance required in high-load environments. At 0.5 inches in diameter and 2 inches in overall length, with a diameter tolerance of 0.0010 decimal inches, it meets ASME B18.8.2 standards and carries a double-shear breaking strength of 51,000 pounds. One end is beveled and one end is rounded for controlled installation and consistent seating.

This oversized dowel pin is suited for applications where standard-tolerance pins have worn or enlarged bore holes, making the oversized specification essential for restoring proper fit in existing assemblies. Typical uses include fixture alignment, die and mold positioning, machine component registration, and structural locating in heavy industrial or military-grade equipment. Installation is performed by machinists, millwrights, and maintenance technicians working with precision assemblies. The pin is sold individually, with a minimum order quantity of 10 units.

Key Features

• Double-shear breaking strength of 51,000 pounds for demanding structural applications
• Diameter tolerance of 0.0010 decimal inches for precise oversized fit
• One beveled end and one rounded end for controlled press or drive installation
• Meets ASME B18.8.2 fastener standard for dimensional and mechanical compliance
• Military specification oversized designation for restoring worn bore alignments

Compatibility

Designed as an OEM-style replacement or upgrade pin for precision mechanical assemblies requiring a 0.5-inch diameter oversized dowel pin conforming to ASME B18.8.2 and military specification standards.

Installation Notes

Installation is typically performed by qualified machinists or maintenance technicians using a press or driving tool appropriate for the bore fit. Power down and de-energize all equipment before servicing any assembly containing dowel pins. Verify bore diameter and surface finish before installation to ensure the oversized pin achieves proper interference or locational fit. Do not force the pin into an undersized bore, as this may cause bore damage or pin failure.
