Application Summary AI generated
GB/T 83-2018 specifies the dimensions, technical requirements, and marking of square set screws with a long dog point and rounded end. It is applied in mechanical assemblies where a screw must be tightened by a wrench (due to the square head) and requires a precise, non-marring spherical tip for positioning or locking components, such as in machine tool fixtures or heavy equipment. This standard ensures interchangeability and performance consistency for fasteners used in industrial machinery and automotive applications.
