Value Collection SF043061 Dowel Pin 1/2x3 in Alloy Steel Gr8

Product Description

The VALUE COLLECTION SF043061 is a precision dowel pin manufactured from Grade 8 alloy steel for use in close-tolerance alignment and fastening applications. The pin measures 0.5 inches in diameter and 3 inches in overall length, with a diameter tolerance of plus or minus 0.0002 inches. Hardness is rated at 50-58 HRC, providing strong resistance to wear and deformation under load. End configuration is one beveled end and one rounded end, conforming to ASME B18.8.2 standards. This pin is suited for machinists, maintenance technicians, and mechanical assemblers who require repeatable, precise component alignment in production or repair environments.

Precision dowel pins in this diameter and length range are commonly used in machine tool fixtures, jigs, die sets, and mechanical assemblies where accurate hole-to-hole alignment is critical. The ASME B18.8.2 standard ensures dimensional consistency for drop-in replacement or new-build applications. This pin is appropriate for both light and heavy industrial settings, including manufacturing, fabrication shops, and automated assembly lines where controlled fit and high shear strength are required.

Key Features

• Grade 8 alloy steel construction with 50-58 HRC hardness for high wear and shear resistance
• Tight diameter tolerance of 0.0002 inches for precision fit in close-tolerance bores
• 51,000 pounds breaking strength in double shear
• One beveled end and one rounded end per ASME B18.8.2 configuration
• Meets ASME B18.8.2 fastener standard for dimensional compliance
• 0.5 inch diameter x 3 inch length suits a wide range of fixture and assembly applications

Compatibility

Designed as a standard ASME B18.8.2 precision dowel pin for use in any fixture, jig, die set, or mechanical assembly that requires a 0.5 inch diameter close-tolerance alignment pin with a 3 inch length.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or mallet with a properly sized driver to avoid damaging the pin or bore. Ensure the receiving hole is reamed to the appropriate tolerance before pressing the pin to avoid galling or bore damage. Always verify hardness and fit requirements before installation, as hardened dowel pins may crack if driven into undersized holes. De-energize or lock out any equipment per applicable OSHA lockout/tagout procedures before servicing assemblies that contain these pins.
