Spring Washer (Square Section)
Often referred to as split lock washers; Spring Washers are used to stop fasteners loosening with vibration. The split section of the spring washer tightens into a nut, and this in turn prevents the nut from rotating with vibration.
Spring Washers come in two types: square section (where the cross-section of split part is square), and rectangle section. These square section spring washers have a smaller diameter, so are better suited for small screws like socket caps.
Standards: DIN 7980; ASME B18.21.1
