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.

1.Hexagonal bolts are widely used both indoors and outdoors. Outdoor applications are mostly for building installations, bridges and roads, and power facilities; indoor applications are mostly for mechanical equipment, medical equipment, and electronic equipment. 2.When hexagonal bolts are used in electronic equipment, medical equipment, and other places, stainless steel hexagonal bolts are generally selected because the surface color of stainless steel is more beautiful and the corrosion resistance is better, which can keep the machine beautiful for a long time. If it is a mechanical equipment with large vibration, it is recommended to choose high-strength hexagonal bolts.

1. DIN7991 adopts countersunk head design, countersunk head screw design so that it can be flush on the surface, will not protrude, increase the aesthetic. At the same time, the hex provides better torque transfer, reducing the possibility of sliding and damage. When the high strength grade (usually 10.9 grade) made of alloy steel is used, it has good tensile and shear resistance. DIN7991 screws make screws easier to install and tighten, and are suitable for applications where frequent disassembly is required 2. Hexagon flat head screw DIN7991 is widely used in many fields, such as automobiles and automobile new energy field, military aerospace field, shipbuilding heavy industry field, medical equipment field, food machinery field, electronic communication equipment field and wind power field.

1.DIN912 hex socket screw, also known as hex socket cylindrical head screw, is a common fastener, widely used in various mechanical equipment and electronic products. The DIN912 hex screw features a cylindrical head with a hexagonal hole at the top that requires the use of an hex wrench to tighten or loosen. This design allows the screw to provide greater torque during installation, while also preventing the screw from loosening during use. 2. Widely used ‌ : common in mechanical equipment, automobile manufacturing and other fields, used to connect parts and provide a stable fixed effect

1. Convenient manual operation: The head design of the butterfly screw increases the lateral force surface, making manual tightening more efficient and labor-saving 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 3. Wide application: Butterfly screws play an important role in multiple industries due to their unique design and excellent performance. Whether in situations that require manual operation or special environments that require insulation, non-magnetic, and corrosion resistance, butterfly screws can provide reliable solutions.

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.
