Dewalt DWA2SQ2IRB Square Recess Screwdriver Bit

Product Description

The DEWALT DWA2SQ2IRB is a square recess power screwdriver bit designed for use with impact-rated power drivers and drill-drivers in professional trade applications. With a 0.25 inch drive and a 2 inch overall length, this bit delivers consistent torque transfer in square recess fastener heads. The compact 2 inch OAL makes it well suited for work in tighter spaces where longer bits would bind or flex. DEWALT manufactures this bit for repeated use under power-tool loads, making it a reliable consumable for electricians, HVAC technicians, carpenters, and general contractors who drive square recess screws regularly.

This bit is appropriate for residential and light commercial applications where square recess drive screws are standard — including electrical panel work, equipment mounting, cabinetry, and decking. The 0.25 inch drive fits standard quick-change chucks on cordless and corded power drivers. Sold individually, this SKU is intended as a replacement or supplemental bit for technicians who maintain bit sets on the job.

Key Features

• Square recess bit profile for positive engagement with square drive fasteners
• 0.25 inch drive size fits standard quick-change power driver chucks
• 2 inch overall length suitable for open and moderately confined fastening locations
• Designed for use with power drivers under repeated torque cycling
• Compact geometry reduces flex during high-cycle driving

Compatibility

Designed as an OEM-style replacement bit compatible with standard 0.25 inch quick-change power driver chucks used across residential and commercial trade applications.

Installation Notes

Installation is performed by inserting the bit into a compatible 0.25 inch quick-change chuck on a cordless or corded power driver. Ensure the chuck is fully seated before driving. Inspect the bit tip for wear before each use — a worn square recess profile causes cam-out and can damage fastener heads. Replace the bit when tip geometry shows visible rounding or deformation.
