A cleat is only one of the essential parts of an integral system; without the other components, the cleat will not work to deliver its purpose. A boat system should conform to the entire system to keep its best function even in rough waters and weather conditions. It consists of the fasteners, nuts, bolts, washers, the mounting platform, the backplates, and the line. Consider potential galvanic corrosion when using the Aluminum cleat. Components should match the material used along with the cleat. If you use dissimilar metals, corrosion may occur in a saltwater environment. This Aluminum Cleat Countersunk -3-046110 has high tensile strength proven for its durability to withstand wear than any other cleat material for docking or mooring. Marine watercraft should have a cleat system proven to work against tremendous shocks and forces. A research study showed that aluminum can sustain a good amount of weight between 3860 to 4570 kilograms depending on the angle, amount of stress or force, and the strength of fasteners.
