Application Summary AI generated
This standard specifies the dimensions, technical requirements, and marking of hexagon washer head drilling screws, which combine a self-drilling tip with a hexagon washer head for secure fastening. It is applied in the assembly of metal sheets, steel structures, and building components where screws must drill their own pilot holes and form mating threads without pre-drilling. The standard is used by manufacturers and quality inspectors in the construction, automotive, and general mechanical industries to ensure interchangeability and performance consistency.
