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.The serrated lock washer is a single ring washer, open type dislocation, when the wrench tighten the nut, the wrong opening of the tooth above the serration will be inlaid to the surface of the member, to prevent the nut from loosening. 2. The lock washer is mainly used with the nut and installed on the bolt, which is a bit like the role of the spring washer. The Serrated Lock Washers is generally used under the bolt head and nut.
DIN582 lifting ring nuts are mainly used to connect chains and steel wire ropes, and can also be used for lightweight lifting. The hanging ring nut refers to a component that is screwed together with a bolt or screw to provide a fastening effect, and is a necessary component for all production and manufacturing machinery.
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.
Specification:①Thickened multifunctional angle code ②Ordinary multifunctional angle code Instalation scope:used for all kinds of tables,chairs,beds,laminated cabinet,etc.
DIN1587 hexagonal cap nuts are mainly used in situations that require high stability and anti loosening. This type of nut is commonly used to fix the tires and front and rear axles of vehicles such as cars, tricycles, and electric vehicles, as well as to secure equipment that is often exposed to sunlight and rain, such as the base of street lamp stands. In addition, DIN1587 hexagonal cap nuts are also suitable for various mechanical equipment to enhance their stability and anti loosening effect.
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.
1.The characteristic of slotted pan head tapping screw is that they can be used without matching nuts.

Whether in situations that require manual operation or special environments that require insulation, non-magnetic, and corrosion resistance, butterfly screws can provide reliable solutions.
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.;
DIN928 welded square nuts are widely used in multiple fields, including mechanical manufacturing, automotive industry, aerospace, photovoltaics, transportation, construction, and more. The characteristics of these application areas require high-strength and reliable fasteners, and DIN928 welded square nuts precisely meet these requirements. It can withstand high-strength tensile and shear forces, suitable for situations that require strong forces and vibrations. The design of the four corners provides better welding performance, making the connection more secure and reliable. It can be installed through welding or threaded connection, making installation simple and convenient. Suitable for various industrial fields, ensuring stability and reliability of connections.
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.
It is used to support structural steel columns, lamp posts, heavy equipment, highway signs, and many other applications. Its hook provides resistance, preventing it from pulling out of the concrete foundation when force is applied. Stainless steel bent anchor bolts are used to secure embedded plates, signage structures, columns, and many other structural objects to concrete.
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.A washer is a seal that fills the gap between two mating surfaces, allowing the two workpieces to be connected together without leakage even when compressed. 2.A washer can fill some irregularities on the surface, allowing for some imperfections in the mating surfaces of the workpieces. washer are generally made by cutting and splitting thin sheets. 3.Generally speaking, the ideal washer material is one that allows a certain degree of deformation so that it can deform and fill the corresponding space (including some slight irregularities) during assembly. Some washer require the addition of sealants directly to the surface in order for the gasket to work properly.
1.Slotted round head wood screws are a type of fastener designed specifically for use in wood connections. 2.Strong fixing ability: Compared with ordinary nails, slotted round head wood screws have stronger fixing ability and can connect wooden parts together more firmly. 3.Easy to remove: Due to their design, slotted round head wood screws can be easily removed when needed without causing too much damage to the wood. 4.Aesthetics: The semicircular head design allows the screw to maintain a good level of flatness with the surface after installation, improving the overall aesthetics. 5. Wide application: Slotted round head wood screws are widely used in many fields due to their unique design.Slotted round head wood screws are widely used in many fields due to their unique design. For example, they can be used to connect and fix wooden boards in furniture manufacturing, house decoration and mechanical equipment, and are also commonly used to install various hardware accessories, such as hinges and hooks.
