Application:

In use, the set screw is screwed into the screw hole of the machine to be fixed, and the end of the screw is pressed against the surface of the other machine, even if the former part is fixed on the latter part. Slotted and hexagon socket set screws are used on the parts where the nail head is not allowed to be exposed. The square head set screws are suitable for the parts that the nail head allows to be exposed. The pressing force of the screw is the smallest with the slotted screw, the lag screw is the largest, and the hexagon socket screw is centered.
