GB9074.1 standard involves cross recessed pan head screw and plain washer assemblies. These assemblies usually consist of a pan head screw with a cross recess and a plain washer to provide a secure connection and prevent the screw from loosening.
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:
Phillips Slot Design: The Phillips slot design on the head of the screw allows for quick tightening and loosening with a Phillips screwdriver or power tool. Pan Head Design: Pan head screws have flat heads that fit flush with the surface of the part being joined, providing a neat appearance. Flat Washers: Flat washers increase the contact area between the head of the screw and the connected part, reducing localized pressure and protecting the surface of the connected part. Anti-loosening properties: Flat washers in assemblies help provide additional friction to prevent screws from loosening due to vibration. Versatility: GB9074.1 standard covers a wide range of sizes and specifications of assemblies to suit different applications.
Scope of Application
Mechanical Manufacturing: In mechanical manufacturing, used to secure rotating or sliding parts such as gears, bearings, bushings, and other components. Electronic Equipment: In electronic equipment, used to secure circuit boards and other components, providing a solid connection. Automotive industry: in the engine, gearbox and other critical parts of automobiles to ensure the correct positioning and fixing of parts. Construction and renovation: in construction and renovation, used to connect various structural components, such as window and door frames, decorative materials, etc.
