Fastenere Sheet Metal Screws are used to fasten one material with another, most commonly sheet metal but can also used to attach metal object with a wooden, plastic or any other kind of surface. || Round heads feature a round top very similar to half of a sphere with a flat load bearing surface on the underside that will hold materials being fastened firmly together. || Phillips drive is a cross head design and is the most commonly used type in America. Phillips is often criticized for its tendency to cam out at lower torque levels but this was actually a deliberate feature of the design, for the purpose of assembling aluminum aircraft without overtightening the fasteners. || 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 out perform and out last all zinc plated fasteners for years with out the need to perform costly and time consuming maintenance. The vast majority of stainless steel fasteners are produced with metals from the austenitic family.
