The DEWALT ACCESSORIES DWA2SQ2IR5 is a 5-pack of 2-inch No. 2 Square impact-ready power bits engineered for use with impact drivers and drills in high-demand fastening applications. Each bit features a Reflex Core that allows up to 15 degrees of flex, reducing breakage under torque. CNC machining provides tight dimensional accuracy for a precise fit in screw recesses, minimizing cam-out. The Flex Torque design channels energy efficiently through the bit, extending service life in repetitive driving tasks. Licensed tradespeople and experienced installers working with decking, framing, and millwork applications will find these bits sized and tempered for sustained impact use.
These bits are suited for residential and light commercial construction, finish carpentry, cabinet installation, and general fastening work where No. 2 Square drive screws are specified. The 2-inch length is a standard fit for impact drivers used in wood framing, decking, and fixture mounting. Sold in a pack of 5, they are practical for job-site use where bit wear and loss are routine factors.
Designed as an OEM-style replacement and standard-use bit for impact drivers and drills accepting 1/4-inch hex shank accessories with No. 2 Square drive bits.
These bits are installed and replaced by tradespeople using standard impact drivers or drills with a 1/4-inch hex chuck. Ensure the driver is powered off or the battery is removed before changing bits. Inspect each bit for wear or rounding before use, as damaged bits increase cam-out risk and can strip fastener heads. Follow manufacturer torque settings on the driver to match the application material.
