For dealing with small, technical & hard-to-reach screws, nuts and bolts, Engineer’s Twin Wrench Driver really gets in there. The design pairs a straight end & 90º angled-end ratcheting driver combo that allows you to use it like a screwdriver or a wrench. It’s got a knurled cushion handle for firm grip without slippage & comes supplied with 10 magnetized bits in a bullet holder, including 1.5mm-4.0mm hex bits, sizes #00, #1 & #2 Phillips plus 4.5mm & 6mm slot head drivers.
