  1. Function: The washer serves to evenly distribute the load exerted by the screw head over a larger surface area. This helps prevent damage to the material being fastened and provides additional stability to the connection.
  2. Design: The washer is typically a flat, circular metal or plastic disc with a central hole that allows it to be placed over the screw shaft. It may have a smooth or toothed surface to improve grip and prevent loosening of the screw over time.
  3. Materials: Washers are commonly made from materials such as steel, stainless steel, aluminum, or nylon. The choice of material depends on factors such as the application requirements, load capacity, and environmental conditions.
  4. Installation: The washer is placed over the screw shaft before it is inserted into the designated hole in the impeller housing. Once the screw is tightened, the washer sits between the screw head and the surface of the housing, providing a stable and secure connection.
  5. Applications: Washers are used in various mechanical and structural applications where screws are employed to fasten components together. In this specific case, they are used in conjunction with screws that secure the impeller housing in place in a water pump or similar device.
  6. Maintenance: Proper installation of the washer ensures optimal performance and longevity of the fastening connection. Periodic inspection may be necessary to check for signs of wear, corrosion, or loosening of the screws. Damaged or worn washers should be replaced promptly to maintain the integrity of the assembly.
