2. Vibration Absorption In mechanical applications, machines and equipment often experience vibrations during operation. Rubber washers act as shock absorbers, reducing the impact of these vibrations on the screw and the surrounding materials. This can prolong the life of both the fastener and the assembly it secures.

3. Toggle Bolts While not purely plastic, these anchors combine a plastic body with a metal toggle mechanism. They are used for extremely heavy applications and are ideal for hollow walls.

4. Infill Bracing Often used in conjunction with walls, infill bracing incorporates structural elements within the boundaries of a frame. This type enhances stability and rigidity while allowing for various design opportunities that blend with the building's overall structure.
