The set screw is used to fasten the relative positions of the two parts. In use, first screw the screw into the female threaded hole of the part to be fixed, and then press the end of the screw against the surface of the other part or the corresponding pit on the surface, even if the relative positions of the two parts are fixed.

Come down. Slotted and hexagon socket set screws are suitable for applications where the screws are not allowed to be exposed. Square head set screws are suitable for applications where the nail head is allowed to be exposed. In terms of the pressing force of the screw, the slotted set screw is smaller, the hexagonal set screw is next, and the square head set screw is larger.

The taper end screw is suitable for parts with low hardness; the truncated cone end screw is suitable for the part with the concave surface at the pressing surface; the flat end and the concave end screw are suitable for the parts with high hardness or frequent adjustment of the fastening position.

The long cylindrical end screw is suitable for tubular shafts (or thin-walled parts), and the cylindrical end of the screw is screwed into the nail hole of the tubular shaft to transmit a large load.
