ZaLoc consists of a ZaLoc bolt with a head seat locking latch and a ZaLoc washer with a matching seat locking latch. By simply assembling the ZaLoc bolt through the ZaLoc washer into the tapped screw hole of the workpiece, it achieves a complete fastening that does not rely on friction. We propose fastening enhancements in the following three series: 1. BoLT ZaLoc: Complete fastening without using nuts. 2. NuT ZaLoc: Complete fastening applicable to stud bolts. 3. Flange ZaLoc: Bolts and nuts for preventing loosening in flange-type shaft joints.

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.
