Range and reference criteria for square nuts
Square nuts can be used in the automotive industry, agricultural machinery industry, construction machinery industry, shipbuilding industry and other places, we usually use household appliances, cars, etc. need square nuts to reinforce. In fact, square nuts are also divided into many specifications and types.
The large size of the head of the square nut makes it easy for the wrench to get stuck or rely on other parts to rotate, and can also be used in parts with T-slots to adjust the position of the nut. Class C square nuts are the same as hex bolts, but square nuts are large in size and have a large force area, and are often used on rough surfaces.
In the International Standard Classification, square nut involve hand tools, electrical equipment and systems for aerospace use, fasteners, and railway vehicles.
In the Chinese standard classification, square nut involve hand tools, electronic components, fasteners, power tools, fasteners, knives, and general parts.
General steps: pan yuan - pickling - cold drawing - cold heading. Considering its weldability at the same time, generally use SWRCH10K or SWRCH15K.
Which welding method is used for square nuts?
Manual welding is usually used to weld, but the disadvantage is that the solder joints are not beautiful;
It is recommended to use a "weld nut", usually not square, but hexagonal;
Welding using spot welding machines is strong and beautiful.
The role of the square nut is to fix the front and rear axles of the vehicle by fastening through the front and rear axle screws, so that the frame and tires are fixed together, in order to prevent the nut from loosening, it must be fixed with an opening pin through the groove of the slotted nut, and the opening pin must be fixed through the middle of the axle screw, usually both ends of the axle screw need to be drilled, the diameter of the hole and the slot width and groove depth of the slotted nut determine what specifications of the opening pin is selected, and the axle screw and the opening pin used are more matched. The nut fixes the front wheel and frame through the axle screw, and the opening pin is fastened to the slotted nut through the hole of the axle screw, so that the slotted nut does not loosen, so that the vehicle does not loosen when moving.
Ningbo yipianhong Fastener Co., Ltd. was established in 2001, specializing in the production of all kinds of high-strength bolts, nuts, and threaded rods, with an annual production capacity of 30000 tons and an annual turnover of 300 million yuan. Products include ANSI / ASTM, DIN, BS, ISO, GB, JS, and other standards, which are mainly used in the field of high-strength seals and oil pipeline valves.
