There are many names for tightening screws, both called machine screws and headless screws, which are screws used to fix the relative positions of mechanical parts. There are also different types of hexagon socket screws, so what are the differences between different screws?
1. Hexagon socket set screws: generally used in places where they are not often disassembled after installation. The pointed section is suitable for parts with lower hardness, and the concave end is suitable for parts with higher hardness.
2. The taper end of the set screw (no tip): It is necessary to make a hole on the top tightening surface of the component first, so that the cone surface is on the side of the hole to increase the load transfer capacity.
3. Cylinder end of the set screw: used to adjust frequently, or to fix the parts installed on the pipe shaft (thin-walled part), the cylindrical end enters the large hole on the pipe shaft, and the shearing effect of the end can be transmitted For larger loads, there should be a device for mimicking loosening when using this screw.
4. Set screw flat end round tip section: It is mostly used at the connection of the often adjusted position, and the transfer load is small. Among them, the flat end has a large contact area and can be used for parts with high top hardness. The top tight surface should be flat; the round tip section requires a U-shaped groove, V-shaped groove or round socket on the surface of the component.
Therefore, when we use different hexagon socket screws, we must use them correctly according to the actual situation.
