1. There are many kinds of set screws on the market, and the types are different. There will be great differences in their scope of use, construction methods, pressure, price, and service life. If the hexagon socket set screws or slotted sets If the screw is used, it can only be used in the occasion where the screw cannot be exposed. If it is a square head set screw, it can be used in the occasion where the nail head is allowed to be exposed.
2. If the types of fastening screws are different, the compressive force will be different. In general, the compressive force of the square head set screw is large, while the compressive force of the slotted set screw is small, and the hexagon socket The compression force of the set screw is moderate.
3. If the set screw is equipped with a tapered end, it can only be used to install on parts with lower strength. If the set screw is not equipped with a tapered end, it can only be used to install on the surface with a concave hole On the parts, so that the ability of the screw to transmit load is increased.
