Application Summary AI generated
GB/T 85-2018 specifies the dimensions, technical requirements, and marking of square set screws with a long dog point, which are used to secure rotating components like gears or pulleys onto shafts in mechanical assemblies. The long cylindrical tip provides precise axial positioning and prevents loosening under vibration, making it critical in industrial machinery, automotive transmissions, and heavy equipment where reliable locking is required. This standard applies to manufacturers and quality inspectors in China for ensuring interchangeability and performance consistency in fasteners for mechanical systems.
