WebbWhat is Screw Dislocation – Crystallographic Defects – Definition Screw dislocations can be produced by a tearing of the crystal parallel to the slip direction. If a screw dislocation is followed all the way around a complete circuit, it would show a slip pattern similar to that of a screw thread. Line defects are generally many atoms in length. • Because of its self-locking property (see below) the screw is widely used in threaded fasteners to hold objects or materials together: the wood screw, sheet metal screw, stud, and bolt and nut. • The self-locking property is also key to the screw's use in a wide range of other applications, such as the corkscrew, screw top container lid, threaded pipe joint, vise, C-clamp, and screw jack.

"WebbLead screws are a very popular way to convert motor rotation into linear translation (Fig. 6.11 ). They can offer fair axial stiffness and very good, smooth small displacements. Lead screws are generally preloaded with an axial load that helps to maintain a permanent contact between the nut and screw filets. " - Screw definition in science
