Engineered for superior performance in demanding environments, this hex lag screw features a unique design that incorporates a conically shaped steel washer bonded to a rubber-like piece. This innovative combination not only protects against leakage but also significantly reduces the likelihood of fasteners loosening due to vibration, making it a reliable choice for applications where stability is critical. The rubber component, made from Style 40 EPDM sheet, works alongside the Grade 2 steel washer, ensuring minimal damage to mating surfaces while providing durability. Mechanically galvanized in accordance with ASTM Specification A153, these 1/4 in x 2 in lag screws offer long-lasting dependability for aerial hardware and line applications.
