  • COMPLETE 8-SET COMBO: Includes 8 sets of 1/2-13 x 2-1/2" Carriage Bolts with matched Hex Nuts and SAE Narrow Washers. Please refer to the 2nd image for precise dimensions (Head Dia 1.09" , Neck Height 0.281", etc.) to ensure a perfect fit for your specific project needs
  • DUAL-LAYER RUST DEFENSE: Made from premium 18-8 (304) Stainless Steel with a Black E-Coating finish. This dual-layer protection ensures a chip-proof, matte black surface that outperforms standard black oxide in harsh outdoor or marine environments
  • SQUARE NECK & ROUND HEAD: The smooth round head provides a sleek, low-profile finish, while the precision square neck locks into wood or pre-drilled holes to prevent bolt rotation during installation. Ensures a secure, one-sided drive that won't loosen under vibration
  • MAXIMUM LOAD STRUCTURAL USE: Designed for major structural projects, the 1/2" diameter is ideal for large piers, retaining walls, heavy machinery mounting, and bridge-like timber structures. These bolts offer maximum load-bearing reliability for the most demanding construction environments
  • MEASUREMENT & INSTALL TIP: Bolt length (1/2") is measured from UNDER THE HEAD to the tip, including the square neck. For best results, pre-drill a pilot hole to ensure the square neck seats fully for a professional, flush-mount finish
