What is Serraloc?

Serration Lock or “SerraLoc” is the latest and ultimate advancement in serration locking technology. Utilizing multiple rows of bi-directional serrations, SerraLoc technology ensures that all rotational forces are halted in both the clockwise and counterclockwise directions utilizing independent serration rings. With its uniquely patented “slant” design, rotational forces are pushed away from the contact point of the serration and into the body of the mating flange itself, ensuring that each serration ring and mating flange face absorb forces in only one direction. This ensures a longer service life for the flange and the multi-use allowance of the washer.
