Product use of set screws

A screw used to fix the relative position of parts. When in use, screw the set screw into the screw hole of the part to be fixed, and press the end of the screw tightly on the surface of another part, even if the previous part is fixed on the latter part. Slotted and hexagon socket set screws are used on parts where the nail head is not allowed to be exposed, and square head set screws are suitable for parts where the nail head is allowed to be exposed. The compression force of the screw is small for slotted screws, large for lag screws, and centered for hexagon socket screws. Conical end screws are suitable for parts with low strength; non-pointed conical end screws are suitable for parts with pits on the pressing surface to increase the ability to transmit loads; flat end screws (the pressing surface should be flat) and Concave end screws are suitable for parts with high hardness or frequently adjusted positions; long cylindrical end screws are suitable for tubular shafts (on thin-walled parts, the cylindrical end enters the hole of the tubular shaft to transmit large loads , but there should be a device to prevent the screws from loosening during use.
