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