Both ends have angled points, but either one or both ends can have a round point. Double-ended studs are used for bolting flanges and in other situations where torching from both ends is needed or desired. Double end threaded studs are also known as dual threaded rods or double-ended studs. It comes with the same amount of thread on both ends or with different amounts of thread on each end (one end has more thread than the other). The Double End Threaded Rod can be used for many different things, like doors and assembly housings. It is usually put into a hole that doesn't have threads and held in place with nuts on both ends. A double-threaded screw is a fastener with threads on both ends of the shaft that are the same length.
