Advantages of Hex Socket Countersunk Flat Cap Head Screw


It is stressed when tightening the screws. The hexagonal hole of the hexagon socket is cylindrical, and the wrench does not slip out when the crossbar is elastic. Or ordinary cross or slotted ones must be pressed from top to bottom and then twisted to tighten, so it is not feasible to add crossbars. For screws with a large force, the inner hexagon must be used.


Commonly used in machinery, mainly for easy fastening, disassembly, not easy to slip angle, etc. The hex wrench is generally a 90° turn, the end of the bend is long and short, and when the screw is short with one side, the length of the hand is long. One side can save a lot of force and can better tighten the screw. The long end is a flat head flat head, the hex socket countersunk flat cap head screw has low cost, low power strength and low precision requirements.


Hex socket countersunk flat cap head screw surface treatment method


1. Screw plating: The electroplated parts are immersed in an aqueous solution containing a deposited metal compound, and an electric current is passed through the plating solution to deposit and deposit the electroplated metal on the parts. Generally, electroplating is performed by galvanizing, copper, nickel, chromium, copper-nickel alloy, etc., and boiled black (blue), phosphating, and the like are sometimes included.


2. Hot dip galvanizing: This is accomplished by immersing the carbon steel component in a plating bath of molten zinc at a temperature of about 510 °C. The result is that the iron-zinc alloy on the surface of the steel piece gradually becomes passivated zinc on the outer surface of the product. Hot dip aluminizing is a similar process.


3. Mechanical plating: The surface of the product is impacted by the particles of the coated metal, and the coating is cold welded to the surface of the product.
