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. Foundation bolts are screw rods used to fasten equipment to concrete foundations. When installed on a concrete foundation, the J-shaped or L-shaped end of the bolt is buried in the concrete. 2. Foundation bolts can be divided into fixed foundation bolts, movable foundation bolts, expansion foundation bolts and adhesive anchor bolts. According to the different shapes, they can be divided into: L-shaped embedded bolts, 9-shaped embedded bolts, U-shaped embedded bolts, welded embedded bolts and bottom plate embedded bolts. 3. Application: Foundation bolts are generally used in infrastructure such as railways, highways, power companies, factories, mines, bridges, tower cranes, large-span steel structures and large buildings. They have strong stability.

1. Transmission function: The rack can convert rotational motion into linear motion. This conversion is crucial in many mechanical devices, such as machine tools, automotive steering systems, etc. 2. Positioning function: In some special machinery and equipment, it is necessary to move objects up and down along a straight line, and the rack can play a positioning role. The vertical teeth on the rack can keep the machine stable during movement and ensure that it can move up or down in a straight line 3. Support and reinforcement function: Tooth strips play a role in supporting weight and strengthening the firmness at the intersection of the upright and horizontal beams of furniture. It is similar to wooden components in architecture, which can enhance the overall stability of furniture In summary, dental strips have different roles in different fields. In the field of machinery, it is mainly responsible for transmission, positioning, and control; In the field of furniture, it plays multiple roles of support, reinforcement, and decoration.

Screws are used to connect two objects. Generally, the head of the screw will protrude above the surface of the connected object, making the surface uneven. Countersunk screws can sink below the surface to make the surface flat. Hard objects need to drill countersunk holes at the corresponding position of the countersunk head. In short, the countersunk head means that the head of the screw can keep the surface flat after installation. And wood screws are used to screw into wood for connection or fastening.

1. A threaded rod is defined as a machined part with external threads on the rod body. It is usually used to join two or more parts together and provide some tensile strength. In general, threaded rods are usually galvanized to improve their corrosion resistance. 2. The DIN975 standard specifies the requirements for the size, material and physical properties of the threaded rod to ensure its quality and interchangeability. This standard has a wide range of applications in construction, machinery, automotive, aerospace and electronics

Cross recessed pan head wood screws are widely used in the following fields because of their unique structure: ● Furniture manufacturing: used to connect various parts of furniture to ensure its stability and strength. ● Automobile manufacturing: used for the tight connection inside the automobile to improve the safety and reliability of the automobile. ● Woodworking: used for the assembly and fixing of wood products to improve the durability of wood products. ● Mechanical manufacturing: used for the assembly and fixing of various mechanical equipment to ensure the normal operation of the equipment.

1.DIN7504K refers to a self-drilling screw with a hexagonal head, a flanged head, and a pointed end.The tail of a self-drilling screw is different from that of an ordinary screw. It is not a pointed tail, but is like a drill bit. This tail allows the screw to drill holes by itself without the need for pre-made holes when screwing into steel plates, wood, etc. 2. Advantages: The biggest advantage is that it does not require auxiliary processing, and can be directly drilled and tapped on the material, which greatly saves construction time. In addition, DIN7504K has higher toughness and maintenance, and will not easily loosen after long-term use, thereby enhancing the stability of the structure. 3. Wide application: Hex self-drilling screws are widely used in the construction industry, especially in the fixing of color steel tiles on steel structures. Because of their easy and firm installation, they can effectively improve construction efficiency and quality. In addition, hexa self-drilling screws are also commonly used to fix thin plates in simple buildings, showing their practicality in a variety of construction environments.

1.The sleeve anchor allows it to anchor into concrete, bricks and blocks. The sleeve anchor works when you insert the sleeve anchor into the pre-drilled hole in the substrate and then turn the nut to pull the working end of the sleeve anchor up through the sleeve. The anchor is then expanded and firmly anchored into the concrete, brick or block. The anchors are available in galvanized and stainless steel. The sleeve anchor is fully assembled and ready to use. 2.Suitable for all kinds of steel structures, cable lines, brackets, gates, stairs, steel ladders and other building components that bear heavy loads of vibration, with reliable post-expansion function for earthquake resistance and durability.

1. Metal-frame anchor are mainly used for expansion anchors of doors and windows. The product is mainly composed of expansion tube screw taper nut.It can firmly fix machines, doors and windows, structural parts, equipment or various appliances on walls, bases or concrete foundations. 2. Advantage: Metal frame anchors have many advantages such as simple installation, firm fixation and convenient construction. 3. Application: Metal frame anchors are widely used in many industries, such as door and window installation, floor installation, fixing heavy objects, etc. In the decoration industry, they can be used to fix decoration materials.
