This fully threaded rod (also known as all-thread rod) measures 3/8"-16 thread size and is 6 feet long. It is made from Grade A steel with a zinc plated finish for basic corrosion protection. Fully threaded rods are versatile fasteners commonly used in construction, plumbing, electrical, and general fabrication applications where adjustable length or continuous threading is required. The zinc plating helps protect the steel from rust in indoor and light-duty environments.
