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.The good expansion curve design greatly enhances the anchoring force of the anchor bolt, and the edge of the tube head can effectively prevent the expansion screw from entering the deep inside the hole due to drilling too deep 2. Widely used :Concrete, natural dense stone, solid brick, solid gray sand brick light concrete, hollow concrete brick, etc.;
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.
DIN6921 flange bolts are widely used in various mechanical equipment and engineering structures, especially in application scenarios facing high tension or strong shear working conditions. Its design features include high strength, high precision, corrosion resistance, and mature technology, ensuring the safety and quality of the connection.
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.
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.
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.
The head of a hex flange bolt consists of two parts: the hexagonal head and the flange face. Its “support area to stress area ratio” is larger than that of a regular hexagonal head bolt, so this type of bolt can withstand higher pre tightening forces and has better anti loosening performance. Therefore, it is widely used in products such as automotive engines and heavy machinery. Hexagonal head bolts with holes and grooves can be mechanically locked to prevent loosening during use.
1. Fixation and connection: The main function of U-bolts is to fix and connect various equipment or objects. Due to its unique U-shaped design, it can firmly secure tubular or sheet-like objects, ensuring that they do not loosen or move during use. For example, in the automotive industry, U-bolts are commonly used to connect and secure steel plate springs to maintain the stability of the car chassis 2. Able to withstand multiple forces: U-bolts can withstand tensile and shear forces, and have strong vibration resistance. This means that it can maintain stability under different stress conditions, making it suitable for applications that require high stability. For example, in bridge, tunnel, and railway construction, U-bolts are widely used to ensure the stability and safety of the structure In summary, U-bolts play an important role in fixing, connecting, withstanding various forces, space utilization, and wide application fields. Its design and material selection make it one of the indispensable fasteners in many industries.
1. The characteristics of the Cup Head Square Neck Bolts are that the head is made into a semi-round ball, a square neck is made under the head, and a square hole is also made correspondingly on the connected parts connected with such bolts. When the bolt is inserted into the connecting piece and then screwed on the nut, the bolt will not rotate due to the square neck. Its head is relatively smooth, and it is not easy to hook other objects. 2. Cup Head Square Neck Bolts is mainly used for connecting parts due to structural limitations are not suitable for hex bolts or bolts are required to have a smooth exposed part of the occasion. Such as the feet of agricultural machinery, wall panels and other places. The bolt is divided into two kinds according to the head size: ordinary and large half round head. The head of the large Cup Head Square Neck Bolts is straight and the diameter is large, but its thickness is slightly thin. This kind of bolt is mostly used in trucks, barges, iron and wood looms, and other wooden structural parts, because the head support surface is large, it is not easy to fall into the wooden connector.
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.
It has a hanging function and is used to hang building decorations under cement prefabricated boards, wooden boards, gypsum boards, decorative boards or other board ceilings; The sheep’s eye bolt has a large cross-sectional diameter, long screw and thread lengths, and can withstand high loads when installed on suspended ceilings.

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.
