The set screws are used to fix the relative position of the mechanism. Screw the set screw into the screw hole of the part to be tightened, and press the end to the surface of the other part, that is, fix the previous part to the next part.
The set screw is usually made of steel or stainless steel, and its tip shape is tapered, concave, flat, cylindrical and stepped. The end of the tapered end or the concave end of the set screw directly tightens the part, which is generally used for the installation after the installation; the end of the flat end set screw is smooth, and the surface of the part is not damaged after being tightened, and is used for frequently adjusting the position. At the joint, only a small load can be transmitted; the cylindrical end tightening screw is used to adjust the fixed position frequently, it can withstand large loads, but the anti-loose performance is poor, and the anti-loose measures should be taken when fixing; The set screw is suitable for fixing parts with large wall thickness.
