• 3. Flange nut

  What is a flange nut?

  Also known as washer nuts, serrated nuts, hexagonal flange nuts, flange nuts, bolt nut,etc., their size specifications are the same as hexagonal nuts, except that their washers and nuts are integrated and have anti slip tooth patterns below, which increases the surface area contact between the nut and the workpiece. Compared to the combination of ordinary nuts and washers, the anti loosening performance is stronger.

  Application scenarios for Flange nut

  Mainly used to connect two pipelines or between pipelines and equipment, due to its good sealing performance, it is mostly used in pipeline connections or workpieces that require the addition of nut contact surfaces to ensure the firmness and sealing of the connection. It can withstand the effects of high pressure and high temperature, preventing leakage and loosening.

• 4. Nylon nut

  What is a nylon nut?

  Nylon nuts are made of nylon, also known as plastic nuts. It has excellent insulation performance, non-magnetic, thermal insulation, light weight, high temperature resistance, high strength, corrosion resistance, and other advantages.

  Application scenarios for Nylon nut

  It is often applied in various industrial fields, especially in the electroplating and communication industries. Compared with ordinary metal nuts, nylon nuts do not generate signal interference such as eddy currents, making them suitable for use in industries such as communication. At the same time, they have better acid and alkali resistance and can be used in strong acid and alkali environments in the electroplating industry.

• 5. Tighten the nut

  What is a fastening nut?

  A single buckle elastic locking nut, often used as a secondary nut in double nut locking structures. Due to its weight being only about 5% of that of a regular nut, it is suitable for aerospace and related applications

  Application scenarios for Tighten the nut

  Generally not used as the main load-bearing fastener, its function is to back tighten the nut to prevent it from loosening, that is, it is used as a locking nut. When using, first tighten the connected part with a regular nut, fasteners houston,then screw on the locking nut and tighten it by hand to make contact with the regular nut. Then, use a wrench to tighten the locking nut by 60 ° to 90 °. When loosening, the hexagonal nut must be tightened. To create a gap between it and the locking nut, the locking nut can be loosened.

• 

• 6. Cap nut

  What is a cap nut?

  A cap nut, as the name suggests, is a hexagonal nut with a cover. The main function of the cover is to prevent the exposed part on the outside from being tightened, so as to prevent moisture or other corrosive substances from entering the inside and thus play a rust prevention role, thereby improving the service life of itself and the connecting parts. Different sizes of bolts use different sizes of cap nuts, while ultra long bolts use higher cap nuts. There is also a self-locking cap nut with twisted threads in the hexagonal area to form a tight friction fit and prevent the nut from loosening due to vibration.

  Application scenarios for Cap nut

  The use of cap nuts is the same as that of hexagonal nuts. Its characteristic is that the main nut is not easy to slide, but can only be tightened with a wrench, a solid wrench, a dual-purpose wrench (open part), or a special square hole socket wrench.nut and bold

  Mainly used for rough and simple components, such as tires and front and rear axles in cars, tricycles, electric vehicles, etc. It can also be used to fix road lamp holders and some mechanical equipment that are often exposed to sunlight and rain.

• 

• 7. Slotted nut

  What is a slotted nut?

  Slotted nuts mainly refer to hexagonal slotted nuts, that is, grooves are machined above the hexagonal nuts. It is used in conjunction with threaded bolts with holes and split pins to prevent relative rotation between bolts and nuts, as shown in GB6178-6181, etc.

  Its function is to be used in conjunction with bolts with holes in the rod, and to insert split pins to prevent loosening.

  Application scenarios for Slotted nut

  Fix the front and rear wheel axles of the vehicle by tightening the screws that pass through the front and rear wheel axles, so that the frame and tires are fixed together. To prevent the nuts from loosening, a cotter pin must be used to fix them through the groove of the slotted nut. To fix the slotted nut, the cotter pin must pass through the middle of the wheel axle screw.

  In practical applications, slotted nuts can be used in mechanical manufacturing to connect various mechanical parts, such as bearings, gears, couplings, etc.

• 8. Butterfly nut

  What is a butterfly nut?

  Butterfly nut is a type of nut with a unique shape, and the protruding curvature of the head resembles a beautiful butterfly. Butterfly nuts not only have high aesthetic value, but also have significant functional applications.

  Generally speaking, butterfly nuts can be divided into cold heading butterfly nuts, cast butterfly nuts, and stamped butterfly nuts according to their different processing techniques. According to their shapes, they can be divided into two basic shapes: square wing butterfly nuts and round wing butterfly nuts.

  Application scenarios for Butterfly nut

  Butterfly nuts do not require other tools when used and are specifically designed for convenient hand tightening operations. The butterfly design of the head increases the lateral force surface, making hand tightening more efficient. They are mainly used in medical devices, wind power, aerospace, office equipment, petrochemical, electronic communication, shipbuilding industries and other equipment that require frequent disassembly and maintenance.

• 

• 9. T-nut

  What is a T-nut?

  A nut that looks like a T can prevent components from loosening and rotating during installation. T-nuts also have shapes such as diamond and square. A plain T-nut without threads is called a slim waisted bolt, which is beneficial for connecting under variable forces. There are specialized high-strength bolts on the steel structure, with larger heads and varying sizes.

  Application scenarios for T-nut

  Easy to install and unload, and easy to install parts in any position, which can greatly improve labor productivity. This is also the reason why T-nuts can be widely used in T-grooves of various milling machines.
