Dewalt Accessories DWAF1SQ3IR3 Square 3 Impact Bits 3 Pack

Product Description

The DEWALT ACCESSORIES DWAF1SQ3IR3 is a 3-pack of 1-inch Square 3 (SQ3) impact screwdriving bits engineered for high-demand fastening applications. These bits feature a redesigned tip geometry that delivers a tighter fit on SQ3 fasteners, reducing cam-out and extending bit life. The FLEXTORQ Zone allows the bit shaft to flex under torsional load, absorbing impact energy and preventing brittle fracture. A 1/4-inch hex shank makes these bits compatible with standard impact drivers and drills. Laser-etched size markings allow quick identification in the field. Licensed tradespeople and experienced DIYers working with decking, framing hardware, and structural fasteners will find this design well-suited to repetitive, high-torque driving tasks.

These bits are intended for use with SQ3 fasteners commonly found in heavy structural screws, timber connectors, and commercial decking applications. The 1-inch overall length suits compact bit holders and right-angle adapters where space is limited. The pack of three provides on-hand replacements for extended job runs without interruption. Suitable for residential and light commercial construction environments where impact drivers are the primary fastening tool.

• 1/4-inch hex shank compatible with impact drivers and standard drill/drivers
• 1-inch bit length suited for compact bit holders and tight-clearance applications
• Laser-etched size identification for quick field sorting
• Sold as a pack of 3 for continuous workflow on high-volume fastening tasks

Compatibility

Designed for use with SQ3 square-drive fasteners and compatible with any 1/4-inch hex quick-change chuck on impact drivers or drill/drivers.

Installation Notes

These bits are installed by licensed carpenters, framers, and general contractors using 1/4-inch hex impact drivers or drill/drivers. Ensure the bit is fully seated in the chuck before driving to prevent slippage and premature tip wear. Do not use with manual screwdrivers or in applications requiring SQ1 or SQ2 bits, as cross-driving will damage both the bit and fastener head. Inspect bit tips regularly and replace when rounding is observed to maintain fastener integrity.
