HARDLOCK Nut Wedging Mechanism to eliminate the thread space
The reason fasteners become loose is the play between the bolt and the nut, and by completely eliminating that play, it is possible to achieve the ideal looseness prevention mechanism. Through much research, Hardlock has developed a fastener in which the wedge principle is applied to nuts. That revolutionary product is the Hardlock Nut.
