Alliance Plastics, FW Series, Standard Washers

Washers are flat, thin plates with a hole in the center that serve a variety of functions in mechanical systems. They are commonly used to distribute the load of a fastener, such as a bolt, nut, or rivet, across a wider surface area, reducing the risk of damage or deformation to the materials being joined. Washers can also function as spacers, springs, wear pads, locking devices, electrical insulators, or vibration reducers. When selecting washers, several crucial factors must be considered, including the inside and outside diameters, thickness, plating, and material. Different types of washers are available to suit specific applications, including flat, external tooth, internal tooth, sealing, and split lock washers. Each type offers unique properties such as improved grip, greater resistance to loosening, or enhanced sealing capabilities. Materials commonly used in the manufacture of washers include steel, stainless steel, brass, aluminum, copper, and specialized alloys. The choice of material is critical to ensure the washer's ability to withstand the intended forces and environmental conditions. Washers find widespread use in various industries, including automotive, aerospace, construction, and manufacturing. They play a critical role in ensuring the stability, reliability, and safety of mechanical systems, preventing damage, and reducing wear and tear on essential components. By providing an additional layer of protection and support, washers contribute to the efficient and effective operation of diverse mechanical assemblies.
