The hexagon socket screw has a rounded screw head on the outside and a hexagonal shape in the middle, while the hexagonal screw is the common screw head with a hexagonal edge. The hexagon socket head screwdriver looks like a "7". Cut the two ends of the hexagonal steel bar and bend it to 90 degrees to form a hexagon socket head screw wrench (available in hardware tool stores). Today, I will introduce the classification, precautions and anti-corrosion methods of hexagon socket screws.

Classification of socket head cap screws

Divided by head: Hexagon socket head cap screws have cylindrical head socket head cap bolts, which are the most commonly used, and there are many types of them.

Divided by material: there is iron, that is, carbon steel and stainless steel. Stainless steel hexagon socket bolts are also available in stainless steel SUS304 and SUS202. Hexagon socket head cap screws (pan head socket head cap screws). Countersunk head hexagon socket head bolt: the head is a flat head, and the inside is a hexagon socket. There is also a special kind of Chinese standard, called headless hexagon socket head bolt, that is, we often call it a machine screw, a payment screw, and a set screw. These are all common names for headless socket head cap bolts, but the meaning is the same. Of course, there are also some flower-shaped socket head socket head bolts. This is rarely used, and it is basically difficult to see in the market.

Matters needing attention for hexagon socket screws

• The customer should negotiate with the manufacturer in advance, and the manufacturer should use high-quality production materials;

• The manufacturer must harden the hexagon socket head bolts that are produced well, and the required hardness must reach the specified hardness;

• Be sure to use the corresponding tools reasonably when using, do not use the wrong tools to hit the hexagon socket bolts for convenience. When hitting the hexagon socket head cap bolts, you do not need too much force, and you must grasp the force to be balanced. M2.5 socket head cap bolts should be able to withstand a torsion force of more than 2N.m under normal circumstances, so this force should be adjusted well and not too hard.

How to prevent corrosion of hexagon socket screws?

Stainless steel screws are made of metal, and there are four main ways to prevent metal corrosion, namely material properties, use environment, interface between materials and environment, and improved metal structure design. If a completely anti-corrosion alloy is used to make stainless steel screws, Unless there is a special need, it is not economically practical, or the complete isolation of the screw surface from the corrosion-producing environment, but it is still not feasible in operation. Improving the metal structure design can improve the influence of special circumstances under certain conditions, but the design of most stainless steel screws cannot be fully guaranteed, and its maintenance effect is not permanent, so anti-corrosion treatment on the surface is currently the most widely used method.

Anti-corrosion treatment on the surface of stainless steel screws refers to the use of various methods to apply a protective layer on the metal surface, in order to isolate the metal from the corrosive environment, thereby inhibiting the occurrence of the corrosion process, or reducing the contact between the corrosive medium and the metal surface. in order to avoid or reduce corrosion.

The protective layer shall meet the following requirements:

• Corrosion resistance, wear resistance, high hardness.

• The structure is tight, intact, and the pores are small.

• It has strong separation and good adhesion with the base metal.

• It is evenly distributed and has a certain thickness.
