Alloy Steel M20 Hexagon Socket Head Bolt Grade 8.8 socket head machine screw

Products Description

Alloy Steel Socket Head Cap Screws are widely used in many industries. This is inseparable from some of the characteristics of screws. Let’s take a closer look. Alloy Steel Socket Head Cap Screws, Let's talk about the characteristics of hexagon socket screws.

Alloy Steel Socket Head Cap Screws, Q235 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 stainless steel screws is relatively high, but the hardness of iron screws is obviously much 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 achieve the hardness of iron screws, iron screws are generally hardened by heat treatment. During the heat treatment process, the screws must be heated evenly, otherwise the hardness of the screws will not meet the requirements. , It will also make the screw easy to bend, which will greatly increase the production cost of the hexagon socket screw. After the heat treatment, the hardness of the iron hexagon socket screw can be increased, but due to the problem of the wire, there is still no way to compare the quality with the stainless steel wire.

One thing to pay attention to for Alloy Steel Socket Head Cap Screws is to try not to let the head of the screw slip during use, otherwise it will make it difficult to remove the screw later. The above is about some characteristics of hexagon socket screws, hoping to help our customers.
