Washers are common mechanical fasteners used to provide support, distribute pressure, and prevent loosening in bolt, nut, and threaded connections. Washers are typically thin, circular discs with a hollow center.

Washers serve several purposes. Firstly, they can be used to increase the stability of a connection. When a bolt or nut is tightened against a workpiece, washers fill gaps and ensure a more secure connection. Secondly, washers help distribute the pressure at the connection point, reducing damage to the workpiece. Additionally, washers prevent thread loosening and provide additional damping and fastening force.

Washers can be made of metal or non-metal materials. Metal washers are commonly made of steel, stainless steel, or copper, offering high strength and corrosion resistance. Non-metal washers can be made of rubber, plastic, or fiber materials, providing good elasticity and insulation properties.

There are various types of washers available for different applications and requirements. Common types include flat washers, spring washers, and lock washers. Flat washers are the most common type, used to provide support and distribute pressure. Spring washers have elasticity and provide additional fastening force and damping effect. Lock washers have special designs to prevent thread loosening.

When using washers, it is important to select the appropriate size and type to ensure compatibility with the bolt and nut. Proper installation and tightening are also crucial for washers to function effectively.

In summary, washers are common mechanical fasteners used to provide support, distribute pressure, and prevent loosening. By understanding the role, materials, and types of washers, we can better apply them to ensure the stability and reliability of connections. Washers have widespread applications across various industries, providing essential support for mechanical connections.
