Fasteners typically include the following 12 categories: bolts, studs, screws, nuts, self tapping screws, wooden screws, washers, retaining rings, pins, rivets, assembly and connection pairs, and welding nails.
The function of each part of the fastener:
Bolt: A bolt is a long strip of metal rod, mostly with threads and a head. It is usually used with nuts to connect two or more components. According to different application scenarios and requirements, bolts can be divided into common bolts, high-strength bolts, stainless steel bolts, etc
Nut: A nut is a hexagonal part with internal threads used in conjunction with bolts. they
Usually screwed together to provide stable connection force and can be easily disassembled when needed.
According to different application scenarios and requirements, nuts can be divided into ordinary hexagonal nuts and high-strength hexagonal nuts
Female, locking hexagonal female, etc.
Studs: fasteners with threads on both ends
Screw: a fastener composed of a head and a screw, divided into machine screws, hex socket screws, and special purpose screws;
Self tapping screw: Similar to machine screws, but the thread on the screw is a special thread for self tapping screws;
Wood screw: The thread on the wood screw is a specialized thread that can be directly screwed into the wooden component;
Washers: A type of fastener in a circular shape, placed between nuts, bolts, screws, and supports;
Retaining ring: plays a role in preventing the movement of parts on the shaft or hole;
Pin: mainly used for part positioning;
Rivet: A fastener composed of a head and a nail rod. Used to connect two parts with holes for fastening, non detachable;
Assembly parts and connecting pairs: Assembly parts refer to the fasteners supplied by the assembly; The connecting pair is a fastener provided by a combination of specialized bolts and nut washers;
Welding nails: Heterogeneous fasteners that are fixed and connected to one part by welding to facilitate connection with other parts.
