About Self tapping Screws. A self-tapping screw is a screw that can tap its own hole as it is driven into the material. Some self-tapping screws are also self-drilling, which means that, in addition to the tap-like flute in the leading threads, there is also a preliminary drill-like fluted tip that looks much like the tip of a center drill.

Made of stainless steel grade 18-8 which offers a high level of chemical and corrosion resistance and strength that will outperform and outlast all zinc plated fasteners for years without the need to perform costly and time consuming maintenance. The vast majority of stainless steel fasteners are produced with metals from the austenitic family. Their high levels of chromium and nickel provide tough corrosion resistance and the ability to withstand considerable physical strain without fracturing, albeit at a higher cost than the martensitic varieties.
