Now, the concept of customization has entered the minds of many people. Even screw fasteners can be customized. Then, the head size of   long brass machine screws  can be customized? The head size of long brass machine screw cannot be customized at will. Why is this?   The following may occur if the head size of the  long brass machine screws  is customizable. One is that if the screw is made cold heading, the head of the screw may not line up. This is because materials have different coefficients of expansion for forming screws, and the machine also has requirements for the range of molding. Therefore, if the size of the head is set too large and too thin, it may not be able to form. The second is to consider the problem of   long brass machine screws  in actual use. Sometimes, there will be a screw turned, the head broke. One is because of the material, the other is because of the design of R Angle under the head, too small will cause the screw head ...

Long brass screw  is also a long screw. There are two kinds, one is made of copper material, and one is surface treatment is copper plating, this premise is that the material is carbon steel, because carbon steel material plating is not easy to fade, if it is stainless steel, it is suggested to maintain the color, not electroplating. Let’s start with long screws made of copper material. Copper wire is divided into H70 brass screw wire, imported brass screw wire, and H68 brass screw wire. These screw wires have excellent plasticity (the best in brass) and high strength, good machinability, easy to weld, very stable to general corrosion, but prone to corrosion cracking.It is the most widely used variety of common brass.Copper wire itself is more expensive, so it will be more expensive to make long screws, which is not difficult to understand the reason for the high price of copper screws; To make long screws with copper wire, domestic or less. Next is the  long brass ...

How could the  brass screw  rust? (1) Brass screw  surface with deposits of other metal elements containing dust or heterogeneous metal particles attached to the humid air, the condensate between the attachment and brass, the two connected into a micro-cell, triggering the electrochemical reaction, Protective film damaged, called electrochemical corrosion. (2)The  brass screw  surface adheres to organic juices (such as melons, soups, sputum etc.), and in the case of water oxygen, organic acids are formed, and the organic acids are used to corrode the metal surface for a long time. (3) The brass surface adhered to acid, alkali, and salt substances (such as alkaline water and lime-wate...
