The basic types of thread connection fittings

　　The basic types of thread connection fittings:

　　The bolt connection

　　There is a gap between the ordinary bolt and bolt hole, low machining accuracy and rod hole. When used to tighten the nut, can bearing axial and transverse loads. Ordinary bolt assembly and disassembly is convenient, the most widely used. There is no gap between bolt rod hinged bolts connected with the hole, and the hole rod machining precision requirement is high, can withstand the lateral load and positioning.

　　The stud connection.

　　Lo Zhu are threaded at both ends, one end to tie in with the nut, one end and is connected with a, one end and is connected with a, this connection is to be connected one thick and often dismantled occasions, demolition, just unscrew the nut.

　　The screw connection

　　No screw nut, simple structure are directly screwed connections within the threaded hole, but not often, demolition, to avoid damage to the internal threads of the hole.

　　The locking screw connection

　　Will be tightly fixed screw is screwed into a connection is a pit in, and at the end of its top in another is connected piece of clothing surface or pre made in the pits, two parts are relatively fixed. This connection is used to transfer power to small parts together with the rotating shaft, to prevent the two parts from the relative displacement.

　　The above four points is the basic type of thread connection pipe.
