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.
GB854 Tab Washers With Long Tab is mainly used to prevent bolts or nuts from loosening in vibration environments, ensuring the stability of the connection.
Wedge anchors are mainly used for heavy-duty equipment such as pipe gallery hangers, seismic support hangers, glass exterior walls, elevator brackets, shelves, and railings. In addition, it is also suitable for concrete and dense natural stone, metal structures, metal profiles, bottom plates, support plates, brackets, machine beams, beams, brackets, etc.
1.Installation steps: ① Punch a hole ② Hammer the casing into the air ③ Screw the screw into the wall anchor ④ Installation is complete 2.Scope of application: Suitable for home decoration, industrial building materials, medical equipment, etc. 3.Product features: small and light, easy to carry, easy to take, strong and durable
1.Sleeve Anchor with Hook is a special threaded connecting piece used to fix pipe support, lift, bracket or equipment on the wall, floor and column. 2. Stainless steel expansion hook is widely used, mainly used in the integrated installation of multimedia classrooms, installation of manhole protective mesh, installation of power Wells, water Wells and other manhole cover protective mesh, curtain hanging and other fields. Lanterns can also be hung on the top, bird cages can also be used horizontally, and more manhole protection nets can be installed.
1It is mainly used to fix pipes such as water pipes or sheet springs such as automobiles, and its material characteristics, density, bending strength, impact toughness, compression strength, elastic modulus, tensile strength, temperature resistance and color are determined according to the use environment 2. U-type is generally used in trucks, it is used to stabilize the chassis and frame of the car. For example, leaf springs are connected with U-bolts. U-bolt is widely used, the main uses: construction installation, mechanical parts connection, vehicles, ships, Bridges, tunnels and railways.
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
DIN929 welded hex nuts are mainly used in scenarios that require high-strength connections and special shaped connections. This type of nut is connected to the connector by welding and is suitable for situations where conventional bolt connections cannot be made, such as when the connector is too thin or irregularly shaped. The welding process is equivalent to turning two separate parts into a whole, melting the metal at high temperature, mixing it together, and then cooling it. An alloy is added in the middle, relying on molecular force, and its strength is generally greater than that of the parent material.
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.
