Engineered for optimal performance in aerial hardware applications, this washer is specifically designed to enhance the grip and stability of bolts and nuts. With a unique curved shape, bent at a 4-1/2 inch radius, it seamlessly conforms to the contours of poles, providing a broader bearing surface that elevates the compression grip of tightened nuts. Made from durable AISI 1018 steel and treated with a hot dip galvanized finish, this washer not only meets ASTM Specification A153 but also ensures long-lasting resistance to corrosion, making it ideal for demanding outdoor environments. At a size of 2-1/2 inches by 2-1/2 inches with an 11/16 inch hole diameter and a thickness of 3/16 inch, it is a reliable choice for various aerial line hardware applications.
