Types of Copper Threaded Studs
Full Threaded Copper Studs
Full threaded copper studs (all-thread studs / fully threaded rods) are threaded along the entire shank length. Used in terminal blocks, busbar connections, battery terminals, and electrical enclosures. Available in metric (M4–M36) and imperial (1/4″ to 1-1/2″) thread standards. Also referred to as: copper all-thread rods, copper threaded rods, copper stud bolts, copper binding posts.
Half Threaded Copper Studs (Double-End Studs)
Half threaded copper studs (double-end studs / stud bolts) feature a plain shank with threaded ends. Used in transformer terminations, high-voltage switchgear, motor terminals, and compressor connections. Available with equal or unequal thread lengths. Also known as: copper double-end studs, copper anchor studs, copper electrode studs, copper terminal studs.
