Hexagon socket screws are widely used in many industries. This is inseparable from some of the characteristics of screws. Let's take a good look at the characteristics of socket screws. For hexagon socket screws, A3 wire is often used. Of course, iron screw wires are also used. For these screw wires, some characteristics of hexagon socket screws can be determined. First of all, the hardness of the stainless steel screw is relatively high, but if it is an iron screw, the hardness is obviously worse. This has a certain relationship with the iron wire itself. The texture of iron itself belongs to a relatively soft category, and there is no way to compare it with stainless steel wire.
However, in order to be able to achieve the hardness of iron screws, iron screws are generally hardened by heat treatment. During the heat treatment process, it is necessary to ensure that the screws are heated evenly, otherwise not only the hardness of the screws can not meet the requirements. , It will also make the screws easy to bend, which will greatly increase the production cost of extra-high hexagon socket screws. After the heat treatment, the hardness of the iron hexagon socket screw can be raised, but due to the problem of the wire, there is still no way to compare the quality with the stainless steel wire.
Precautions for the use of hexagon socket screws: One thing to note about socket screws is to try not to let the screw head slip during use, otherwise it will make it difficult to remove the screw in the future. The above is about some characteristics of the hexagon socket screws, I hope to help our customers.
