Star Washer (Multwing Washer)

1. Shape: It has a star-like shape with multiple points or teeth.

2. Function: The teeth bite into the material (usually metal or plastic), preventing the fastener from loosening due to vibrations or rotational forces.

3. 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.
