Introduction to the materials and uses of the hexagon socket screws produced by Shenzhen Heat Hardware Co.,Ltd

The hexagon socket combination screw produced by Heatscrew Hardware is generally a combination of a hexagon socket cup head screw with a spring washer and a flat washer combined with screw thread. The editor found that the general material of hexagon socket screws in the market is 8.8 grade hexagon socket screws. Generally, manufacturers use screw wire 10B21 to produce. The hardening reaches 8.8 level, but hydrogen removal is required to prevent the spring washer and hexagon sockeT bolt from breaking.

The materials of hexagon socket screws are divided into iron and stainless steel. Iron is made of different iron screw wires. Specializing in the production of hexagon socket screws, the wires of hexagon socket screws generally use 1010, 1018, 10B21, etc. 10B21 is used to make 8.8 grade combination screws. Like the 8.8-level hexagon socket combination screw, 10B21 wire is commonly used to make it. After finishing, go to heat treatment. After the heat treatment,remove the hydrogen and electroplating. This is to prevent the spring washer of the hexagon socket screw from breaking. Stainless steel combination screws, in our combination screw market, generally refer to stainless steel SUS304 combination screws. 201 combination screws generally do very little. 201 combination screws are rarely produced. Because the hardness of stainless steel 201 screw material is not well controlled, it is easy to produce cracks.


The hexagon socket screws produced by Heat Hardware are often used in machinery. They mainly have the advantages of easy tightening, disassembly, and not easy to slip corners. The hexagon socket wrench is generally a 90° turn, and the bent end is long and the other is short. When screwing on one side, holding the long side can save a lot of force and better tighten the screw. The long end has a round head (a hexagonal cylinder is similar to a sphere) and a flat head,and the round head can be easily removed and removed , To install some parts that are not convenient for the wrench. The manufacturing cost of the outer hexagon is much lower than that of the inner hexagon. Its advantage is that the screw head (the position of the wrench) is thinner than the inner hexagon, and some places are not replaceable by the inner hexagon In addition, the machine with low cost, low power strength, and low precision requirements uses much less internal hexagon screws than external hexagons.
