Engineered for longer shelf life, all bits in this DeWalt 26 Piece Impact Screwdriving Set stem from their EXTREME® FlexTorq™ range, featuring a built-in torsion zone that has been specifically designed to absorb and control high-impact forces. By transferring them into the optimised geometry of the bit tip, the load on the driver and fastener is reduced which means a more secure fixing! The full-fit head also eliminates wobble and screw head rounding too.
