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.

Sheet Metal Screws are used to fasten one material with another, most commonly sheet metal but can also be used to attach a metal object with a wooden, plastic or any other kind of surface. Pan heads have a domed top with a flat load bearing surface on the underside that will hold materials being fastened firmly together. The slot screw drive has a single slot in the fastener head and is driven by a flat-bladed screwdriver or common blade object. This drive is the best choice for the future maintenance of a project that could be potentially covered with paint or other coatings giving an easy option to clear the slot to unfasten. Self Tapping points are a thread forming screws that when installed into the mating material will create threads that are reusable. 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.
