A Cylinder Piston Flat Washer distributes a load in connection points over a larger area, which can help to reduce stress and prevent damage to the material being fastened together. By distributing the load over a larger surface area, the washer helps to prevent the fastener from digging into the surface or causing it to deform.Attributes:• Prevent damage to surfaces, and ensure proper tightening of fasteners• Hardened to Rockwell Hardness Scale value of C25, which indicates its strength and impact resistanceApplications:A Cylinder Piston Flat Washer helps to prevent damage to the material being fastened and provides a more secure connection by reducing the risk of the fastener digging into the material or loosening over time.
