The RivetKing® UNOBolt® is one of the strongest blind structural rivets available in a blind, mechanically locked form. This unique fastener utilizes technology developed from Lockbolts and Collars, except, the SupraBolt™ can be installed from one side of the application. Often used in infrastructure applications where ultimate strength and reliability is paramount. The rivet is installed with a specialized riveting tool affixed with a special nose piece which is used to deform the head by swaging the body into the grooves of the mandrel creating a mechanical lock. Typical applications include rail, bridge, construction, structural pallet racking, truck/trailer and solar panel systems. Tamper proof, vibration resistant with maximized clamp load, shear and tensile strength.
