This fully threaded rod (also known as all-thread or ATR) measures 5/16"-18 thread size and is 6 feet long. It is made from Grade A low carbon steel with a zinc plated finish for basic corrosion protection. Fully threaded rods are versatile fasteners used when continuous threading is needed for adjustable length or precise positioning. The zinc plating helps protect against rust in indoor and light outdoor environments. Common uses include anchoring, suspending equipment, assembling structures, and general fabrication.
