For connecting sheet metal to sheet metal, Sinsun Fasteners' self-drilling screws with hex washer heads are employed. These screws have characteristics that make it easier for them to overcome the limitations of metal-to-metal fastening. The screws are heat treated to significantly improve their strength and holding power. It is offered in stainless steel, carbon steel, and alloy steel to withstand more abuse and increase its resistance to corrosion. There is no need to drill a pilot hole before using these self-tapping screws.
These screws must be used with a washer to guarantee that the structure doesn't become loose over time, despite the fact that they are typically used for fastening metal to metal.
