These industrial hooks are ideal for wider parts or multiple styles of parts with varying thicknesses. When the product sits into the bottom of the "C", the system creates maximum loading and repeated usage. Hooks with a wire diameter of .180 or less are made from hard drawn spring wire that can handle higher loads and can better withstand repeated stripping cycles than cold rolled steel. Mandrel packaging is standard on many of our hooks. Mandrel packaging eliminates tangling and increases productivity. The hook desription will indicate if the products ships with our exclusive Mandrel Packaging.
