SOLID-LOCK® - introducing a new and improved wedge locking washer . Since the beginning, SOLID-LOCK® washers have been subject to continuous development with constantly improved production techniques. This has resulted in the establishment of a state-of-the-art manufacturing facility providing the world’s best bolt securing system.
SOLID-LOCK® washers are composed by two washers (1 pair) which are "glued" together, providing an assembly-friendly and time-saving fastening concept.
This pair consists of 2 identical washers both having a set of cams on one side and a S serration on the other. These washers wedge each other and lock themselves due to the fact that angle “α” of the washer cam is larger greater than the angle “β” of the bolt/screw thread. By fastening the bolt/screw on the washer, the S serrations on the outside, will grip into both the head of the bolt and the surface material, utilizing tension (instead of friction) to lock the bolted connection.
