Brass machine screws

Material Characteristics

Brass is the main material used in the production. Brass has good electrical conductivity, which makes the screw can play a role in some mechanical devices that require electrical conductivity, such as the metal casing connection of electronic equipment, it can prevent static electricity accumulation. Brass also has good corrosion resistance, especially in some mildly corrosive environment of the mechanical devices outstanding, such as in the presence of a small amount of water vapour or weak acidic and alkaline environments, can effectively resist corrosion, to extend the service life of the screw. At the same time, the relatively soft texture of brass, which makes in the tightening process is not easy to damage the threads of the connected parts.

Specifications and dimensions

Size mainly includes thread diameter and length. Thread diameter commonly has a variety of specifications, such as M2, M3, M4, etc., where the number after the M represents the nominal diameter of the thread, the size of the diameter determines the size of the load that the screw can withstand. Length, according to the needs of the actual mechanical device, from a few millimetres to tens of millimetres, for example, in some small electronic products in the shell fixing, may use the length of 5 - 10mm brass round head Phillips machine screws, while in some larger mechanical structure connection, may use the length of 20 - 30mm screws.

application scenario

In the field of electronic equipment,Brass Machine Screws widely used in chassis, circuit boards and other parts of the fixed. Because of its good electrical conductivity and a certain degree of corrosion resistance, to ensure that the equipment is connected to a solid at the same time, to meet the electronic equipment for the electrostatic discharge and other performance requirements. In precision machinery manufacturing, such as watches, small instruments, etc., also often use this screw. The design of its round head cross is convenient for installation and disassembly, and the brass material is relatively soft, will not cause damage to precision parts, to ensure the assembly quality of precision machinery.
