Bolts: A type of fastener consisting of a head and a screw. It is required to cooperate with a nut to fasten two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
The screw is mainly used for a part with a tight threaded hole, and a fastening connection with a part with a through hole, does not require a nut to fit (this type of connection is called a screw connection and is also a detachable connection; it can also be Nut fittings for tight connection between two parts with through holes.) Set screws are mainly used to fix the relative position between two parts. Special-purpose screws such as eyebolts are used for lifting parts.
