Common materials for set screws
It is a kind of screw used to fix the relative position of the machine.It is classified according to the slot type.It can have hexagon socket set screws, inner plum set screws, slotted set screws, and square head set screws without slots, etc. , The available materials are stainless steel, iron, brass, aluminum, titanium, etc.
Characteristics of set screws
A set screw with parallel first end surface and second end surface, with a threaded section between the first end surface and the second end surface, two parallel grooves extending radially in the direction of the first end facing the second end surface The wall, the connection between the two groove walls-the bottom of the groove, by which a radial groove is defined by the groove wall and the bottom of the groove; it is characterized in that the adjacent parts of the groove wall and the thread section have-from the thread section to the groove wall The inclined side abuts the inclined surface, and the groove bottom and the abutment portion of the threaded section also have a bottom abutting inclined surface that converges toward the groove bottom.
The role and use of set screws
The positioning pin of the set screw plays the same role, and is generally used to connect two parts to play a fixed role, and this screw can be screwed in as a whole, so that it looks smooth and looks good. When using a set screw, screw the screw into the internal threaded hole of the part to be fixed, and then press the end of the screw firmly on the surface of the other part (or the corresponding recess in the surface), even if the two parts are The relative position is fixed. The usage scenarios of flat end, concave end and cone end are different, and the corresponding uses are also different. Slotted sockets, inner plum and hexagon socket set screws are not suitable for applications where screws are exposed, and square head set screws without slots are suitable for applications where screw heads are allowed to be exposed.
Uses of set screws
Set screws are commonly used in mining, metallurgy, textiles, various precision machinery, precision instruments, meters, electronic products, communication products, locks, toys and other industries! Prioritized for applications requiring simple equipment and parts, easy to install, with The dual-structure sealing device can work in harsh environments. The structure has various forms, good versatility and interchangeability.
Set screws should also be customized according to different application scenarios. Basically, the hardware store basically fails to meet the requirements. It has an internal hexagon at one end and several standards at the other end. Such as DIN916.DIN915.DIN914.DIN913. The specifications of the set screws are from M1.6-M12, and the length is from 4MM-50MM. Specifically, it is divided into hexagon socket female set screws, hexagon socket flat set screws, hexagon socket set screws, and hexagon socket set screws.
