    Bolts have a head on one part and the other end is threaded. This is mostly used in conjunction with a nut and this helps to stay in one place. Screws are the same as bolts as the head on one and thread on the other.

    Studs are threaded from both ends and there is no head in it. It allows the components to get joined with each other and threaded from internally. The threads have 2 major standards which include:
