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.

In addition to their sealing capabilities, neoprene washers also provide vibration and shock absorption. When used in conjunction with self-tapping screws, they help to mitigate the impact of vibrations that can loosen fasteners over time. This is particularly crucial in automotive and machinery applications where constant movement and vibration are present. The resilient nature of neoprene ensures that the screws remain securely fastened, reducing the risk of mechanical failure.
