Value Collection 251325PR Oversized Dowel Pin Alloy Steel

Product Description

The VALUE COLLECTION 251325PR is a military specification oversized dowel pin machined from alloy steel for use in precision alignment and fastening applications. The pin measures 0.5 inches in diameter and 1 inch in overall length, with a diameter tolerance of 0.0010 inches for tight, repeatable fits. End configuration is one beveled end and one rounded end, which aids in guided insertion during assembly. Hardness is rated at 50-58 HRC, supporting a breaking strength of 51,000 pounds in double shear. This pin conforms to ASME B18.8.2 and meets military specification requirements. Licensed machinists, tooling technicians, and maintenance professionals working in defense, aerospace, and heavy industrial environments are the primary installers.

This oversized dowel pin is suited for applications where standard-diameter pins no longer hold acceptable tolerances due to hole wear or rework. The oversized diameter allows machinists to ream worn bores to a new, precise size and restore correct alignment without replacing the mating component. Typical uses include fixture plates, jig bodies, machine bases, and structural assemblies that require accurate, load-bearing pin registration. The alloy steel construction and high HRC hardness rating make it appropriate for high-cycle or high-load environments common in industrial production and defense maintenance depots.

Key Features

• Military specification oversized dowel pin conforming to ASME B18.8.2
• Alloy steel construction with 50-58 HRC hardness for wear resistance under load
• 51,000-pound breaking strength measured in double shear
• Diameter tolerance of 0.0010 inches for precision bore fitment
• One beveled end and one rounded end for guided, controlled insertion
• Oversized diameter supports bore rework and alignment restoration

Compatibility

Designed as an ASME B18.8.2-compliant military specification oversized dowel pin for precision alignment applications in fixtures, jigs, machine bases, and structural assemblies requiring controlled pin-to-bore fits.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. The mating bore should be reamed to the appropriate oversized diameter before pressing or driving the pin. Power down and de-energize any machinery before servicing pinned assemblies. Do not force-drive the pin into an unprepared or undersized bore, as this can damage the bore or distort the pin.
