What are the main parts of non-standard fasteners for mold wholesale? It mainly includes bolts, studs, screws, nuts, self tapping screws, wood screws, etc. Jiaxing Chengda Mold Co., Ltd. is an enterprise specializing in the production of various high-strength fasteners. Mold manufacturers are committed to providing customers with good fastening connection schemes and high-quality fastening products.
(1) Bolt: a kind of fastener consisting of head and screw, which shall cooperate with nut to fasten and connect two parts with through-hole. This connection mode is called bolt connection.
(2) Stud: a kind of fastener without head and with threads on both ends. During the connection, one end of it needs to be screwed into the part with internal thread hole, and the other end needs to pass through the part with through hole, and then screw on the nut, even if the two parts are tightly connected into a whole.
(3) Screw: it is also a kind of fastener composed of head and screw. It can be divided into three categories according to its use: machine screw, set screw and special purpose screw. The machine screw is mainly used for the fastening connection between a part with a tight set threaded hole and a part with a through hole. The screw is mainly used to fix the relative orientation between two parts without nut cooperation.
(4) Nuts: with internal threaded holes, generally in the shape of flat hexagon column, and also in the shape of flat square column or flat cylinder. Cooperative bolts, studs or machine screws are used to fasten and connect two parts, making them a whole.
(5) Self tapping screw: similar to machine screw, but the thread on the screw is special thread for self tapping screw. It is used to fasten and connect two thin metal components to make them a whole. Small holes need to be made on the components in advance, because such screws have high hardness and can be directly screwed into the holes of the components to form corresponding internal threads in the components.
(6) Wood screw: It is also similar to the machine screw, but the thread on the screw is a special wood screw thread, which can be directly screwed into the wood component, and is used to connect a metal part with a through hole with a wood component. This kind of cohesion is also attributed to the ability to separate cohesion.
