Taper end set bolts

A set screw (headless screw) is a kind of screw specially used to fix the relative position of the machine, and the role is equivalent to the positioning pin. It is a full screw rod, which is connected to each other through two holes, and the two ends are tightened and fixed with a wire cap.

When in use, screw the set screw into the screw hole of the part to be fixed, and press the end of the screw on the surface of the other part, even if the previous part is fixed on the latter part. Slotted and hexagon set screws are used on machine returns where the nail head is not allowed to be exposed, and square set screws are used on parts where the nail head is allowed to be exposed.

Tapered set screws are commonly used screws in machine building. The threaded end of the tapered set screw is tapered, and the tapered end screw is suitable for small strength parts.
