Sea-Dog Weldable Cleat - Cast 356-T6 Aluminum - 8" - 046048

Key Performance Features

• Cast 356-T6 Aluminum: This specific temper (T6) provides superior hardness and structural integrity. It is the industry standard for marine components that must endure significant tensile loads.

• Weld-Ready Base: The bottom of the cleat is designed with a clean, flat profile to ensure a high-quality bead and deep penetration during the TIG or MIG welding process.

• Corrosion Resistance: 356 aluminum has a high silicon content which provides excellent resistance to salt-water corrosion, making it ideal for coastal and offshore environments.

• Smooth Profile: The cast design features rounded edges and a smooth finish to prevent rope chafing and minimize wear on dock lines.

• Structural Reliability: Eliminates the "working" or loosening that can happen with traditional bolts over time in high-vibration or high-impact environments.

Installation & Welding Pro-Tips

• Preparation: For the strongest bond, ensure the welding surface on the boat or dock is ground down to bare, bright aluminum and cleaned with Acetone or a stainless steel wire brush immediately before welding.

• Process: TIG (Tungsten Inert Gas) welding is the preferred method for this cleat to achieve a clean, aesthetic bead that matches the high-quality cast finish.

• Filler Rod: Use a compatible 4000 or 5000 series aluminum filler rod (like 4043) to ensure the weld remains flexible enough to handle the stress of line tension without cracking.

• Post-Weld Treatment: While 356-T6 is corrosion-resistant, many builders choose to anodize or powder-coat the cleat after it has been welded to the structure to provide a finished, uniform appearance.
