Product Details

The Dorman 803-335 is a heavy-duty Grade 5 hex head cap screw designed for automotive, marine, and general mechanical applications requiring reliable fastening strength. This precision-engineered bolt features 7/16-14 coarse thread and measures 3-1/2 inches in length, making it ideal for applications requiring extended reach through thicker materials or mounting brackets.

Key Specifications:

  • Grade 5 medium carbon steel construction with zinc plating for corrosion resistance
  • Thread size: 7/16-14 UNC (Unified National Coarse)
  • Length: 3-1/2 inches measured under head
  • Hex head design for secure tool engagement with standard wrenches and sockets
  • Meets SAE J429 Grade 5 specifications with 120,000 PSI minimum tensile strength
  • Zinc finish provides protection against rust and oxidation in various environments

Grade 5 fasteners offer excellent strength-to-cost ratio for most automotive and mechanical assemblies, providing significantly higher strength than Grade 2 fasteners while being more economical than Grade 8. The coarse thread pattern allows for faster installation and better performance in softer materials or applications requiring repeated assembly and disassembly. Dorman's quality manufacturing ensures consistent threading and precise head dimensions for reliable torque application.
