Threaded Rods are long rods much like the threaded portion of a bolt, but are commonly much larger and do not feature a head. Threaded fasteners are often used with coupling nuts in tension assemblies. Coupling nuts offer the ability to connect multiple threaded items together. Reducer coupling nuts offer the ability to couple different rod sizes. Fully threaded bars are used to join and stabilize structures or objects, often into ceilings or walls. Threaded fastener strength varies by size and material, making a solution for all rod needs.
