What is the difference between screws, bolts and screws

In life, bolts, screws, screws, etc. are often mentioned. What is the difference between them? In fact, the standard argument is that there are no screws and nuts. Screws are commonly referred to as “screws” with external threads. The shape of the nut is usually hexagonal, and the barrel nuts screw inner hole is internal thread, which is used to cooperate with the bolt and tighten the related parts. The nut is commonly called, the standard should be called “nut”. The head of the bolt is generally hexagonal, and the shank has an external thread. The screw is small, the head has a flat head, a cross head, etc., and the rod has an external thread. The actual stud should be called “double-ended stud”, both ends have external threads, and the middle is generally a polished rod. The long end of the thread is used to connect to the deep hole, and the short end is connected to the nut.

bolt

Bolts are widely used in detachable connections in mechanical manufacturing, and are generally used in conjunction with nuts (usually plus a washer or two washers).

Screw

Screws are usually used alone (sometimes with washers). They are generally used for tightening or tightening and should be screwed into the internal threads of the body.

Stud

Studs are mostly used to connect one of the connected parts with a large thickness, and need to be used where the structure is compact or the bolt connection is not suitable due to frequent disassembly. Studs are generally threaded at both ends (single-end studs are threaded at one end). Usually, one thread is firmly screwed into the body of the component, and the other end is matched with a nut to play the role of connection and fastening. To a large extent, it also has a fixed distance function.
