1.DIN6923 hexagon flange nut and general hexagon nut compared with the size and thread specifications are basically the same, but more than the hexagon nut with one ring flange, equivalent to the washer and nut are integrated, and there is a ring of non-slip tooth grain on the flange surface, also known as tooth flange nut. 2. Widely used ‌ : hexagon flange nuts mainly play a role in increasing the contact surface with the workpiece, mostly used in pipelines, fasteners and some stamping parts and casting parts. The flange face of DIN6923 flange nut itself has the function of anti-slip and stop, and it does not need to add flat pad and spring pad when assembling, which is more convenient to use

1. The cap nut and stainless steel hexagonal slotted nut are matched with an open pin and threaded bolt with holes to withstand vibration and alternating loads, which can prevent the nut from loosening and coming out. 2. Cap shaped nuts with inserts, which rely on tightening the nut to tap the internal thread, can provide anti loosening effect and have good elasticity. The purpose of the 3-cap nut is the same as that of the hex nut. Its characteristic is that when assembling and disassembling, a wrench is used to clamp the main nut, which is not easy to slip. However, only an adjustable wrench, a fixed wrench, a dual-purpose wrench (for the opening part), or a specially designed square hole socket wrench can be used for assembly and disassembly. Mostly used on rough and simple components. 4. Cap nuts are suitable for high-strength fasteners, mechanical fasteners, furniture fasteners, vehicle fasteners, machining special-shaped parts, cold heading special-shaped fasteners, double headed foot U-wires, and building decoration fasteners

1. The eye lifting nut is a part that is used to tighten the nut together with the bolt or screw. It is an essential component for all manufacturing machinery.There is a thread under the nut, which can be drilled according to its different specifications and fixed with the screw.Eye lifting nuts are often used in conjunction with external threaded columns to lift various equipment, such as molds, chassis, motors, etc. 2. Wide application: Eye lifting nuts are widely used in many fields to provide safe and reliable connection, such as industrial lifting, aerospace, construction engineering and steel structure.

1. Determine bearing capacity: The diameter of the nut is directly related to its bearing capacity. Generally speaking, the larger the diameter, the stronger the load-bearing capacity of the nut. This means that when subjected to high loads, it is necessary to choose nuts with larger diameters 2. Impact on installation space: The diameter of the nut can also affect its installation space requirements. When designing mechanical structures, it is necessary to consider the diameter of the nut to ensure sufficient space for installation and operation. 3. Standardized production: The DIN934 standard specifies the diameter of nuts, which helps to achieve standardized production of nuts. Standardized production not only improves production efficiency, but also ensures the quality and interchangeability of nuts. The diameter parameter in DIN934 standard plays a key role in the application of nuts, which not only affects the function and performance of nuts, but also relates to the stability and safety of the entire mechanical structure.

1. Hex nuts are mainly used in conjunction with bolts or screws to achieve the connection and fastening of two or more parts. The design of hex nuts enables them to have good torque transmission capabilities and can withstand large axial and radial loads. 2. Characteristic: There must be enough operating space during installation. You can use an adjustable wrench, open-end wrench or glasses wrench during installation. All of the above wrenches require a large operating space. 3. Wide application: It is widely used and is characterized by its strong tightening force. Hex nuts cover almost all areas where fasteners are needed. For example: construction engineering, machinery manufacturing, electronic products and home repair, etc.

Through its specially designed shape, DIN981 round nuts can provide high locking force, ensuring a tight connection between components. This type of nut comes in multiple specifications, suitable for different bolt diameters and connection requirements. Made of galvanized or stainless steel materials, it has good corrosion resistance and is suitable for various environments. Tightening and loosening can be achieved through simple rotation movements, making the operation simple.

DIN557 single chamfered square nuts are mainly used in applications that require high-strength connections and corrosion resistance, such as power engineering, road transportation, home building materials, and other industries. The design features of this nut include a single-sided chamfer, which is easy to install and can improve the stability and reliability of the connection.

Hex nuts are used in conjunction with bolts and screws to primarily connect and tighten mechanical components. Hexagonal nuts of different types and grades are suitable for different occasions to meet different precision and surface treatment requirements. Widely applicable, with strong fastening force, suitable for occasions requiring large operating space. ‌

DIN937 hexagonal slotted thin nuts are mainly used for machines and equipment that require frequent disassembly, especially in situations where space is limited. This type of nut has six parallel short grooves at its bottom, which can be rotated using a wrench or pliers, making it easy to disassemble and install

DIN935-1 hexagonal slotted nuts are mainly used to fix the front and rear axles of vehicles. By tightening the screws that pass through the front and rear axles, the frame and tires are fixed together. In order to prevent the nut from loosening, it is usually fixed by using an open-ended pin that passes through the groove of the slotted nut. The open-ended pin needs to pass through the middle of the wheel axle screw, and usually both ends of the wheel axle screw need to be drilled. The diameter of the hole and the width and depth of the slotted nut groove determine what specification of open-ended pin is selected.

Cage nut, also known as square hole card nut or floating nut, consists of an elastic material shell and a square nut. The groove structure of its shell positions the nut in the pre drilled square hole, and due to the gap between the combination of the shell and the square nut, it can compensate for the positional deviation of the installation hole. Cage nuts have high-strength threaded fastening function, quick and convenient installation, can be disassembled and repositioned, and can also be tilted and fixed.
