An External Tooth Lock Washer provides enhanced fastening stability for screws or bolts used on the electronic panel. The outward‑facing teeth bite into the mounting surface and the underside of the fastener head, helping maintain strong tension at the joint. This design reduces the risk of loosening caused by vibration, thermal expansion, or repeated electrical operations. By keeping the fastener firmly seated, the washer supports stable mounting of electronic components, reduces joint movement, and helps preserve proper alignment of the panel.Attributes:• Provides strong locking action through outward‑facing teeth.• Helps prevent loosening of fasteners on the electronic panel.• Supports stable seating of screws or bolts.• Reduces vibration‑related movement at the joint.• Component type is a narrow‑rim type.Applications: An External Tooth Lock Washer is installed under the fastener head used to mount components on the electronic panel. It helps maintain screw tension, prevent loosening, and support stable panel performance under vibration and operational changes.
