What is the difference between bolt and set screw?
If a set screw does have a head, the thread will extend all the way to the head (whereas a bolt might have an unthreaded shank between the head and thread). The set screw passes through a threaded hole in the outer object and is tightened against the inner object to prevent it from moving relative to the outer object.
Is there any difference between bolt and screw?
Screws are generally turned into an object, like a piece of wood, so the head needs to be bigger than the surface. The shafts of bolts are not tapered, whereas many screws are tapered. The main difference between a bolt and a screw is that a typical screw can work on its own and a bolt requires a nut to secure it.
