Why buy two tools when you only need one? The PROXXON FLEX-DOT Combination-Screwdriver combines a screwdriver with a nut driver in a single unique design. The tip has a 1/4″ hex quick release socket ready to take screwdriver bits. Pulling back, the quick release socket reveals a male 1/4″ square drive tip, ready to take 1/4″ square drive sockets for dealing with nuts or bolts. The rounded two-component handle features PROXXON's flexible nub design for fatigue-proof and comfortable continuous use. It provides an excellent grip, with high torque transfer. Blade length 110mm.
