Shape: It has a star-like shape with multiple points or teeth.
Function: The teeth bite into the material (usually metal or plastic), preventing the fastener from loosening due to vibrations or rotational forces.
Material: Star washers are commonly made from steel, stainless steel, or other metals for durability and strength.
Automotive: Often used in car assemblies, machinery, and other vehicles to ensure that bolts stay tight despite vibrations.
Electrical: Sometimes used in electrical connections, as they can help maintain a secure connection.
Construction: Utilized in various industrial applications to secure fasteners.
Star washers come in two common types:
External Star Washers: The prongs face outward, and they are used to bite into the material being fastened.
Internal Star Washers: The prongs face inward, and they are typically used in situations where a fastener needs to be secured against another fastener, like a bolt and nut.
