Threaded Rods

Threaded rods are 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. They are designed to be used in tension. Threaded rod in bar stock form is often called all-thread. The direction of the rotation caused by a threaded rod depends on whether the rod has a right-hand thread, left-hand thread, or both.  Depending on the specific type of threaded rod, the threading may extend just partially, or it may extend all the way. Regardless, all threaded rods feature threading on both ends, making it particularly useful in applications where tension is applied.
Their main usage to stabilize structures can be inserted into various materials like concrete, wood, or metal to either temporarily create a steady base during construction or they can be installed permanently.
