Impact Drivers and break loose rusted, corroded, and generally stubborn screws. Their 5/16 in. hex shank is a nearly universal size that will also fit many other manual impact drivers. They are made from high-strength chrome vanadium steel, heat treated for excellent impact performance, and completed with a sandblasted finish. Each tip is precisely machined to fit fastener head, helping to prevent further damage to it while coaxing the fastener loose. Featuring the four most commonly used sizes, in two different lengths, these bits fit screws on many cars, trucks and other vehicles.
