The Mac Tools Mac-Grip Screwdriver line includes features and benefits to maximize torque, reduce slippage and remove fasteners quickly and are available in slotted, Phillips, torx, tamperproof torx, nut drivers and square tip. The quad-lobular, four-sided handle fits comfortably inside the hand, allowing the user to apply even more torque than tri-lobe handle designs, according to the company. The larger main body is ergonomically designed to fit large and small hands and provides the ultimate grip to maximize torque. An extended thumb rest stabilizes the user’s grip and provides additional comfort and control for optimal torque. The tapered nose provides a “speed grip” to remove a fastener quickly.
