Value Collection 241478BR Precision Dowel Pin 1x3 in Grade 8

Product Description

The VALUE COLLECTION 241478BR is a precision dowel pin designed for accurate alignment and location of mating components in mechanical assemblies. Machined from Grade 8 alloy steel with a hardness of 50-58 HRC, this pin delivers the wear resistance and shear strength required in demanding industrial and tooling applications. At 1 inch in diameter and 3 inches in overall length, it conforms to ASME B18.8.2 standards, ensuring dimensional consistency across tooling, jigs, fixtures, and production machinery. The breaking strength of 204,000 pounds in double shear makes it suitable for high-load alignment tasks. It is installed by machinists, toolmakers, and maintenance technicians.

This dowel pin is suited for use in precision tooling, die sets, fixture plates, machine frames, and structural assemblies where tight positional tolerancing is required. The one beveled end and one rounded end configuration simplifies press-fit installation into reamed holes. It is appropriate for both original equipment manufacturing environments and maintenance and repair operations requiring reliable, repeatable part location.

• One beveled end and one rounded end for controlled press-fit installation
• Conforms to ASME B18.8.2 dimensional and material standards
• 1 inch diameter by 3 inches overall length

Compatibility

Designed as an OEM-style and replacement precision dowel pin for use in any application requiring ASME B18.8.2 compliant Grade 8 alloy steel pins with a 1 inch diameter and 3 inch length.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a hydraulic or mechanical press. The mating hole should be finish-reamed to the appropriate tolerance before installation to ensure proper fit and alignment. Never hammer a precision dowel pin into an under-reamed hole, as this can damage the pin surface or distort the bore. Follow applicable ASME and shop-standard procedures for press-fit component installation.
