L/R screw
Redefining loosening countermeasures, NejiLaw's L/R screws.
The L/R screw is a "non-loosening screw" with an innovative fastening method that does not rely at all on the conventional principle of preventing loosening through pressure contact friction. It features a special three-dimensional structure in the form of an L/R bolt that does not have a helical structure capable of engaging both left-hand and right-hand nuts. By screwing a right-hand nut and a left-hand nut onto this L/R bolt and mechanically coupling these nuts together on the L/R bolt, it is possible to create a state that does not loosen mechanically.
