Profile: Universal Rivet, Inc. specializes in manufacturing rivets and specialty cold-headed products. Our products include a full line of semi-tubular, solid, and shoulder rivets. Our cold headed parts finishes include brass, black oxide, nickel, tin, and zinc yellow & black. Door hinge & pulley applications both use solid rivets for strength and durability. Oval head rivets are the most common type of rivets, with a wide variety of fastening applications. Flat head shoulder rivets are often used when the pieces joined by the rivet are free to rotate. Special purpose rivets can be designed for almost any application, from aluminum ladders to zinc plated rollers.
