Bolts are cylindrical threaded fasteners that require the use of nuts. It consists of two parts: head and cylinder with external thread. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
A fully threaded bolt is a bolt without a shaft, that is, it is threaded from head to toe except for the head. Partially threaded bolts are ordinary bolts, and the threaded part is not from head to toe, but only a part. Due to the large force of many connectors, the half-threaded part is on the outside of the joint of the workpiece, while the inner part of the force is smooth without threads, which can improve the mechanical strength of the bolt and help to withstand greater torque.
If clamping strength is of greatest interest and alignment and shear strength are less of an interest, then fully threaded bolts may be an option. A fully threaded bolt means that all the tension applied to the bolt is distributed over the entire structure, which means it can handle more force than a partially threaded bolt. Full threaded bolts are used in environments that rarely require shear and tend not to loosen much. Once installed, a fully threaded bolt spreads pressure along its entire length, with the greatest holding pressure at the head where it meets the material being held.
