This Toughseries Screwdriver Set was designed to prevent damage caused by environmental elements with 10X more resistance to corrosion compared to standard levels. Tackle a range of jobs with the high-grade durability each of these hand tools provides with their nickel-coated tips and black chrome finishes. The Screwdrivers were built with S2 steel bars for bend resistance while the integrated Max fit tips help reduce stripping and slippage for full contact with fasteners. Use the soft, bi-material handle to comfortably grip and fasten or loosen screws with high torque.
