Leaf chain anchor bolts or clevises are made from high-tensile alloy steel according to the required breaking strength and individual application stresses.
Most normal applications are simple and can use a standard product but occasionally unusual stresses such as tension, compressions, shear and bending affect will require a special design.
Square and rectangle chain blocks are manufactured from high-grade alloy steel that is at least as strong as the chain they are fitted to. They can be designed with holes or sheer face and in materials suitable for welding.
