Aluminum Automotive Flat Washers - Request for Information


Aluminum: is a metal with composition properties that include durability, malleability and a notable weight to strength ration.  Aluminum is one of the most widely used manufacturing materials as a result of its easy machinability and resistance to corrosion. 


Automotive:  this industry deals with the development and manufacturing of automobiles and vehicular products for commercial and official purposes.  A wide range of parts and components are used that must endure a range of operational and environmental circumstances imposed by consumers.  


Flat Washers:  primarily used with other hardware, such as nuts and bolts to distribute forces in the process of tightening.  Tightness is determined by pattern features such as nominal screw sizes, screw pitch thread, interior and exterior diameter ratios and height. 


Washers: circular hardware used for spacing, load distribution, sealing and vibration reduction.  Washers are produced through stamping and shaping a variety of materials including various metal, plastic, rubber and fiber.
