All washers are well packaged and conveniently stored in a plastic box.
This set contains washers of different sizes to meet different requirements.
A lock washer exerts a spring force between the head of the fasteners and the base, which keeps the washer firmly on the ground and the screw thread on the nut or base with thread, creating greater friction and greater resistance to rotation.
