Value Collection 241205PR Precision Dowel Pin 5/16x5/8 in

Product Description

The VALUE COLLECTION 241205PR is a precision dowel pin manufactured from Grade 8 alloy steel and held to ASME B18.8.2 dimensional standards. It measures 5/16 inches in diameter and 5/8 inches in overall length. The pin features one beveled end and one rounded end, and carries a Rockwell hardness rating of 50-58 HRC, making it suitable for high-load locating and alignment applications. The diameter tolerance is held to 0.0002 inches, enabling tight, repeatable fits in precision-machined bores. Installation is typically performed by machinists, toolmakers, and maintenance technicians working in manufacturing, fabrication, or mechanical assembly environments.

This dowel pin is used in fixture building, jig construction, die sets, and general mechanical assembly where accurate part-to-part alignment is required. The combination of alloy steel construction and Grade 8 material rating makes it appropriate for applications involving significant shear loading. It is sold individually but carries a minimum order quantity of 100 pieces per order, making it suited for production and shop stock applications rather than single-unit repair.

Key Features

• ASME B18.8.2 compliant precision dowel pin
• Grade 8 alloy steel construction for high shear-load applications
• 50-58 HRC Rockwell hardness for wear resistance and durability
• Diameter tolerance of 0.0002 inches for tight, repeatable bore fits
• One beveled end and one rounded end for guided press-fit installation
• Double-shear breaking strength rated at 20,000 units per ASME standard

Compatibility

Designed as a standard ASME B18.8.2 precision dowel pin for use in machined fixtures, jigs, dies, and mechanical assemblies requiring a 5/16-inch diameter locating pin with a 5/8-inch length.

Installation Notes

Precision dowel pins are typically pressed or driven into reamed bores using an arbor press or dead-blow mallet. The bore diameter and finish should be verified against the pin tolerance before installation to ensure proper fit class. Always confirm the bore is clean and free of burrs or debris before pressing the pin. Pins should not be hammered directly on the head face without a proper driver to avoid deforming the end geometry.
