Drive long slotted screws with zero wobble. A spring-loaded sleeve slips over the screw to keep it straight while you tighten. The sleeve also keeps your fingers off the fastener threads, so you can steer clear of cuts and friction burns. However, since these bits only have two points of contact, they may slip out of the fastener head if you use too much force.
Quick-Change Hex Shank—Lock these bits directly into power tools. They won't wobble as much as bits paired with an adapter, so they are the best choice for high-precision tasks.
Steel—Best for dry environments, since moisture will cause these bits to rust.
