The GB805 fastening nut, also known as an all-metal hexagonal locknut, is a fastener used to prevent nuts from loosening. These nuts usually use nylon or other material inserts to provide a locking function, which can maintain the stability of the connection in a vibrating environment.The GB805 standard specifies the scope of use of fastening nuts, materials, appearance requirements, dimensions, mechanical properties, product grade, and inspection methods to ensure the quality of fastening nuts and the safety of their 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:

Anti Loosening Performance: Inserts made of nylon or other materials are used to provide a reliable locking function and prevent the nut from loosening under vibration environments. HIGH STRENGTH: Usually made of high-strength steel, capable of withstanding large preload forces. Corrosion Resistant: Surface treatments such as zinc plating, blackening or Dacromet treatment provide additional corrosion protection for use in wet or corrosive environments. Variety of sizes: Thread sizes range from M6 to M48 to meet the needs of different sized connections. Economical: Due to its standardized production, it is cost-effective and suitable for large-scale applications.

Scope of Application

Machinery and equipment: Used to secure parts in machinery and equipment to prevent loosening due to vibration. Automotive: Used to ensure the fastening of critical components in the assembly and repair of automobiles. Aerospace: Due to their lightweight and high strength properties, they are also used in the aerospace sector. General engineering: In general engineering and construction projects for connections requiring high stability.
