GB Standard

GB standards for fasteners are national standards (GB) developed by the Standardization Administration of China (SAC). Used to specify the dimensions, materials, mechanical properties and technical requirements of fasteners such as bolts, nuts, washers and screws. Some GB standards are equivalent to ISO (international standards), for example, GB/T 5783 is equivalent to ISO 4014.

  • GB: Mandatory national standards (must be followed).
  • GB/T: Recommended national standards (voluntary, but generally followed by the industry).
