ADD Double-toothed lock washer
This washer is used in panel assembly using holes and groves which are much bigger than the diameter of the screw or bolt, in order to achieve evenly distributed pressure over the entire area of contact.
The ADD washer is also very useful when fastening two panels together.
Lateral movement can be avoided as the panels remain fixed in a static position.
The diameter of the washer chosen should be far greater than the diameter of the hole or groove in order to ensure sufficient contact area. The advantage of the use of the ADD washer is that the specific pressure is spread over a greater surface area in materials which are softer than steel.
