Clevises are used to connect tie rods and hanger
assemblies to structural steel or fabricated lugs. The pin connection ensures that the rod is loaded only in tension and sees no bending forces. Our clevises are widely used in structural steel bracing and pipe support applications.
Finishes: Plain (black) & Galvanized.
Haydon stocks clevis forgings in C1035 steel, ASTM A668 Class A, and 316 stainless steel, ASTM A473 Designation A. Heat-treated carbon and alloy steel clevises are available by special order.
