Screwdriver sets contain multiple screwdrivers in different tip sizes and styles for screwing (tightening) or unscrewing (loosening) a variety of screws. A typical screwdriver has a handle and a shaft that has a tip at the end that’s inserted into the screwhead before turning the handle. The handle is shaped to provide a secure and comfortable grip. The shaft is steel construction to resist bending or twisting, while the tip is often hardened to resist wear and chipping. Screwdrivers have different shaft lengths to reach screws in hard-to-reach locations.
