wafer head reamer self drilling screws

The black coating on these screws adds an additional layer of utility. Typically, this coating is a form of zinc plating or a powder coat finish, which serves two primary purposes. Firstly, it enhances the screw's corrosion resistance, protecting it from rust and wear, especially in outdoor or humid conditions. Secondly, the black color offers a sleek, unobtrusive appearance, making it suitable for applications where a discreet fastener is desired.

Structural bolts are made from high-strength materials such as grade 5 or grade 8 steel, making them resistant to corrosion and wear. They are heat-treated to achieve the necessary tensile strength, which can range from 120,000 to 180,000 pounds per square inch (psi). This high-strength capacity is crucial for withstanding the dynamic forces and stresses that structures face over time, including wind, seismic activity, and the weight of the structure itself.
