The DEWALT ACCESSORIES DWAF2SQ3IR3 is a 3-piece set of SQ13 impact screwdriving bits engineered for professional fastening applications. Each bit measures 2.25 inches in length and features a 1/4-inch hex shank compatible with standard impact drivers and drills. The FLEXTORQ Zone absorbs torsional impact stress, extending service life significantly over standard bits. An overhauled Phillips 2 geometry improves cam-out resistance and increases screw output per bit compared to previous generations. Bits are laser etched for fast, reliable identification in the field. This set is sold as a pack of 3 and is designed for tradespeople who drive fasteners under sustained load.
The DWAF2SQ3IR3 bits are suited for residential and commercial construction, mechanical assembly, and finish work where consistent fastener engagement is critical. The 1/4-inch hex shank allows rapid bit changes in impact drivers and standard drills. The FLEXTORQ Zone design is particularly well-suited for applications involving high-torque impact drivers where standard bits fail prematurely. Compatible with T20 through T40 fasteners, these bits address a wide range of fastening tasks encountered on the job site.
Compatible with T20 through T40 fasteners. The 1/4-inch hex shank fits standard impact drivers and drills accepting 1/4-inch hex accessories.
Insert the 1/4-inch hex shank fully into the bit holder or chuck before driving fasteners. Inspect bits for wear or deformation before each use and replace when drive geometry shows visible damage. Use appropriate personal protective equipment when operating impact drivers at high torque settings.
