Hex washer head self drilling screws have a drill point at the tip of the thread drills its own pilot hole in to metal allowing for quick installation and fastening while saving time and effort with just a single step. Made from an ultra strong stainless steel grade 410 giving them the ability to drill through sheet metal and stainless steel while still being wear resistant and offering a mild chemical corrosion protection; these screws are not intended for use with aluminum as the higher iron content in the fastener will cause embrittlement; 410 Stainless steel is always MAGNETIC due to the higher iron content giving the drilling capabilities. These screws have a hex head that can be driven with a nut driver or socket and can be adjusted with a wrench; the built in flanged washer adds a secure grip to the material being fastened into while also preventing the head from crushing thin metal. The self drilling point also referred to as a tek can self drill metal up to a thickness of 0.090 inches and is best used with a lot of pressure and a slow drill speed; if drilling too fast you could run the risk of over heating the metal drilling tip which could cause it to wear out or warp.
