General purpose nuts: there are hexagonal nuts, square nuts, etc. Hexagon nuts and hexagon bolts are widely used, according to manufacturing precision and product quality is divided into hexagon nuts A, B, C grade product grade. Non-standard fastener manufacturers use hexagonal thin nuts as auxiliary nuts in fastening equipment, to play the role of clamping, or for flange connection vice key area to withstand shear forces. Hexagonal thick nuts corner thick nuts are mostly used for connection. Square nuts with square bolts, wrench stuck not easy to slip, mostly used for rough, simple structure.
● Slotted nuts: the key is the hexagonal slotted nuts, that is, the hexagonal nuts on the processing of the slot. Cooperate with screw with hole bolt and cotter pin to avoid relative rotation of bolt and nut.
●Locking nut: Non-standard shaped nut processing refers to the nut with clamping function, including nylon insert hexagonal lock nut and all-metal hexagonal lock nut. Hexagonal nylon ring lock nuts have very reliable fastening capacity, use temperature of -60~100℃ and under certain material standards, have the advantages of not destroying bolts and connections, and can be loaded and unloaded frequently.
● Special purpose nuts: custom processing of pre-built nuts such as butterfly nuts, cap nuts, knurled nuts, embedded nuts, etc. Butterfly nuts can generally be disassembled without tools, and are generally used where frequent disassembly and less stress are required; cover nuts are used in areas where the top screw button must be covered.
