A threaded rod, also known as a stud, is a relatively long rod that is threaded on both ends; the thread may extend along the complete length of the rod.[1] They are designed to be used in tension.[2] Threaded rod in bar stock form is often called all-thread (ATR); other names include fully-threaded rod, redi-rod, continuously-threaded rod, and TFL rod.[3]
Galvanized steel,[3] mild steel, stainless steel, nylon, brass, copper, aluminum, and titanium are all commonly used to make threaded rods.[4]
