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
1.Hex self-tapping screws are mainly used in connection situations that require higher torque and stability. Its hexagonal head design allows it to be tightened with a wrench or socket to provide greater torque. 2. Wide application: Hex self-tapping screws are widely used in various industrial and civil fields due to their high strength and easy operation. For example, they can be used for metal plate connection, building structure, mechanical equipment, electronic products and communication equipment. They can also be used for fixing and connecting various parts in automobile manufacturing and shipbuilding. In addition, hex self-tapping screws can also be used in places with high corrosion protection requirements.
Product description: Hexagonal tail punch bolts are also called opening holes and safety hole screws. Common standards include GB/T31.1. They are mainly used to prevent the workpiece from loosening after the equipment is fastened and connected. They are mainly used to prevent the bolts from vibrating and loosening during use, so they are also called safety hole screws.
The significant feature of the flange bolt with anti slip teeth is that its bottom is designed with serrated protrusions, which greatly enhances the fit between the bolt and nut, effectively avoiding loosening problems caused by vibration or prolonged operation. This feature makes toothed flange bolts an ideal choice for high load and high vibration situations, such as heavy machinery equipment, automotive power systems, and fine electronic equipment. In these applications, the stability and reliability of the connecting components are key factors in ensuring the quiet operation of the equipment, and the excellent anti loosening performance of the flange bolts with anti slip teeth has won widespread recognition and application.
Advantages: High strength: Made of high-quality steel, after strict heat treatment process, it has high strength and hardness and can withstand large loads. Corrosion resistance: Surface treatment such as galvanizing and chrome plating can be performed to enhance its corrosion resistance and is suitable for various harsh environments. High reliability: After strict quality inspection, the dimensional accuracy and performance stability of the product are ensured, and the reliability of the connection is guaranteed.
Stud is used to connect the fixed link function of the machine, both ends have threads, the middle is a screw, there are thick and thin. The thick one is called the thick rod or type A, and the thin one is called the thin rod or type B. Mainly used for connecting parts too thick do not use bolts or due to frequent disassembly should not use screw connection occasions, the stud is usually one end screwed into the screw hole, one end is connected with a nut. Each end of an equal length stud is configured with nuts. Generally used in mining machinery, bridge construction, automobiles, motorcycles, boiler steel structure, hanging tower, long-span steel structure and large buildings, flange connectors, machinery and equipment, pipelines, pump plants, motor plants, construction projects, sewage pipes, machine tools, engines and so on.
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.
In the field of construction, hexagonal bolts are widely used. They are used for steel structures, installation of large machinery, bridge construction, etc. Especially in steel structure buildings, hexagonal bolts are used as high-strength bolts to connect and fix steel structure components, ensuring the stability and safety of the structure 2. Insulation and non-magnetic properties of butterfly screws: Butterfly screws have the characteristics of insulation and non-magnetic properties, which make them particularly useful in situations where electromagnetic interference needs to be avoided, such as in medical equipment, electronic devices, and communication devices In addition to the above-mentioned industries, hexagonal bolts also play an important role in the assembly of daily necessities such as furniture, sports equipment, doors and windows. Their convenience and reliability make them an ideal choice for various assembly tasks.
The T-bolt can be directly placed into the aluminum profile groove, and it can automatically position and lock during installation. It is often used in conjunction with flange nuts and is a standard matching connector for installing corner pieces. It can be selected and used according to the width of the profile groove and different series of profiles.
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.
GB62.2 Butterfly Nut (Square Wing Butterfly Nut) is mainly used in occasions that require frequent disassembly and installation, especially suitable for furniture, mechanical equipment, and automotive fields. Its design features include flat square wings on both sides, allowing the nut to be easily rotated by fingers without the need for tools, thereby improving the convenience and efficiency of operation.
Hexagonal embedded locking nut is a type of fastener that can lock threads. It is widely used in fields such as mechanical manufacturing, automotive manufacturing, and electronic equipment. In high-speed mechanical equipment, locking nuts can effectively prevent thread loosening and ensure the safe and stable operation of the equipment.
DIN125 gaskets are mainly used to connect two objects, fill gaps, and play a role in sealing, supporting, and fastening. It is widely used in various mechanical equipment, pipeline systems and other connections, with good sealing performance and mechanical strength.
Improve connection tightness: The internal locking washer uses its locking teeth to fill the gap between it and the connecting body by applying pressure during equipment assembly, thereby achieving fastening and locking effects. This design can effectively reduce the risk of connection failure, improve equipment efficiency, and reduce maintenance costs
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.
