Screws are the most versatile type of fastener, featuring a raised helical thread and a sharp or flat point used to fasten pieces of metal, wood, and plastic. Screw fasteners can have a straight or tapered shaft and can be tightened using a screwdriver, wrench, or hex wrench, depending on the screw head style.
