The GB70.1/DIN4762 standard deals with Hexagon cylindrical head machine screws, which are a common type of fastener widely used in a variety of mechanical equipment and electronic products. This type of screw is characterized by a cylindrical head with a hexagonal drive slot at the top, which requires the use of a hexagonal wrench for tightening or loosening. This design allows the screw to provide greater torque during installation and also prevents the screw from loosening during use.
Carbon Steel: Typically used for general applications.
Stainless Steel: For environments where corrosion resistance is required.
Alloy Steels: Used in applications requiring high strength or high temperature resistance.
Advantage:
HIGH STRENGTH: GB70.1/DIN4762 screws are usually made of high-strength steel, such as carbon steel of performance class 12.9 or stainless steel A2-70, with good mechanical properties and corrosion resistance. Precise Threads: Precise thread tolerances ensure compatibility and reliability with other fasteners. Variety of materials: In addition to carbon steel and stainless steel, non-ferrous materials can be selected to suit different working environments and corrosion resistance needs.
Scope of Application
Mechanical Manufacturing: In the field of mechanical manufacturing, it is used to fix rotating or sliding parts such as gears, bearings and bushings. Automotive industry: in the engine, gearbox and other critical parts of automobiles to ensure the correct positioning and fixation of parts. Electrical equipment: In electrical equipment, used to keep electrical connectors and terminals in place and prevent loosening due to vibration. Aerospace: in the aerospace sector, to ensure the precise installation and fixing of critical components to withstand extreme operating conditions.
