A main difference between Lockbolt/Huckbolt tension and shear fasteners (other than their application) is in the empty weight and useful load.
The two-piece lockbolt consists of a grooved pin and a sleeve, and once installation is complete, the sleeve is permanently fixed so it can only be removed with a special cutting tool.In fact, a lockbolt is stronger than a conventional nut and bolt with a lock washer, a rivet, or a weld.
Today, Huck bolts are made out of a variety of materials, with many different styles for specific applications. Huck fasteners are most often used in manufacturing, mining equipment, shipbuilding, and agriculture, as well as in trucks, trailers, bridges, railways, and railcars, where vibration is ever-present.
