Wafer-head self-drilling screw for thin sheet metal

The wafer-head self-drilling screw is used for assembling structures made of thin sheet metal thanks to a number of features.

Advantages of the screws

The widespread use of this type of fastener is due to a number of advantages:

1. The drill point eliminates the need for pre-drilling;
2. Large head diameter;
3. Simple installation of the screw.

When selecting a fastener, its length is taken into account.

The wafer-head self-drilling screw is used in construction and mechanical engineering for fastening products and materials to metal sheets and frames. It has a dense single- or double-start thread. The end of the screw has a drill point, allowing work without pre-drilling in metal up to 4 mm thick. The wafer-head self-drilling screw is made of carbon steel, electro-zinc-plated, yellow-passivated, or phosphated with subsequent oiling.
