This Picquic is for everyone. Designed with a solid handle for maximum comfort and torque, the SIXPAC Plus has no moving parts to break or lose. The lifetime guaranteed aircraft alloy shank with hex bolster fits to a 7/16 in wrench to increase torque for stubborn screws. The standard, 3 in power bits are precision-machined and hardened to stand up to heavy use. The 1/4 in hex makes SIXPAC Plus bits ideal for use in drills and impact drivers.
