GB858 stop washers for round nuts are mainly used to prevent loosening of round nuts and are widely used in electrical appliances, elevators, and mechanical fittings, especially when fixing rolling bearings, with significant effects.
1.The biggest feature of drywall screws in appearance is the trumpet head shape. They are divided into double-line fine-thread drywall screws and single-line coarse-thread drywall screws. The biggest difference between the two is that the former has double threads. 2. Easy installation: Drywall screws are easily driven through the drywall sheet and secured to the frame by hammering it directly into place without the need for pre-drilled holes. 3.High Strength: Drywall screws are made of metal and have high strength and compression resistance. 4. Wide application: Drywall screws are usually used for interior decoration to install various gypsum boards, ceilings, lightweight partitions, light steel keels, etc.
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.

Drop in anchors are mainly used for situations where the embedded depth is shallow, by tightening the nut to expand the expansion tube and achieve fastening. This type of screw is suitable for concrete substrates, easy to install, and has high bearing capacity.
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. Cross groove large flat head self tapping screw: The head of the cross groove large flat head self tapping screw is designed as a large flat head, which increases the force area and makes the screw less likely to be damaged when subjected to large torque 2. Easy to install and not easily deformed: Due to its large flat head design, this type of screw is more convenient to install and has the characteristic of not easily deformed, so it has been deeply loved by people in recent years 3. Corrosion resistance: Especially the cross groove flat head self tapping screws made of austenitic stainless steel A2 have super strong corrosion resistance and can resist air, water, acid, alkali salt or other corrosive media. They are suitable for fields such as medical and chemical industries that require corrosion resistance
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. 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

Characteristics: Wedge Anchors do not have high requirements for the depth and cleanliness of concrete cavities and are easy to install. 3. Application: Wedge anchors are usually used in heavy-duty facilities and are suitable for concrete and dense natural stone, metal structures, metal profiles, base plates, support plates, brackets, railings, windows, curtain walls, machines, beams, girders, brackets, etc.
DIN125 gaskets are mainly used to connect two objects, fill gaps, and play a role in sealing, supporting, and fastening. It is widely used in various mechanical equipment, pipeline systems and other connections, with good sealing performance and mechanical strength.
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.
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
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.
