Hexagon socket screws are often used on machinery. They are mainly used for easy fastening, disassembly, and easy slipping. The Allen key is usually a 90° turn. The bent end is long and short. When using a short side to screw, Holding the long side can save a lot of force and can better tighten the screw. The long end has a round head (hexagonal cylinder like a sphere) and a flat head. The round head can be easily removed and removed. Some installation is inconvenient. The part of the lower 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 replaced by the inner hexagon. In addition, the cost is low, and the power is low. Machines with low strength and low precision require less hexagon socket screws than external hexagons.
Hexagon socket screws are used in a wide range of small, small hardware, small electronic products, and electrical products. Mechanical equipment products, large to cars, ships, aircraft cannons. In short, Hexagon socket screws are mainly used in electronics, electrical appliances, electrical, electric power, chemical, water conservancy, mechanical equipment, furniture and other fields.
Hexagon socket head screw plating is generally referred to as iron hexagon socket screw plating, and stainless steel hexagon socket screws are rarely plated. Iron hexagonal screw plating is environmentally friendly and environmentally friendly. Hexagon screw environmental protection plating has environmentally friendly blue zinc, environmentally friendly color zinc, environmentally friendly nickel, environmentally friendly black zinc, environmentally friendly white zinc, environmentally friendly black nickel and so on. Hexagon socket screws are not environmentally friendly, such as white zinc, color zinc, black zinc, black nickel, white nickel, black, blue and white zinc.
Of course, there are some special electroplatings, which are more like Jun Green, Dacromet. If the stainless steel hexagon socket screw needs to be plated, it is also possible. However, in order to increase the salt spray time of the stainless steel hexagon socket screw, it is generally used to pass the plating passivation treatment. Stainless steel hexagon socket screws are sometimes required by customers. In order to make the product and the stainless steel hexagon socket screw the same color. The stainless steel screws are plated.
