Irwin IWAF31SQ22 No. 2 Square Impact Insert Bit 2-pack

Product Description

The IRWIN IWAF31SQ22 is a No. 2 Square screwdriver insert bit designed for impact drive applications. At 1 inch overall length, this bit fits standard 1-inch insert bit holders and quick-change chucks used in impact drivers, electric screwdrivers, and drill drivers. The square point tip engages Robertson-style fasteners commonly found in cabinetry, decking, and general construction assemblies. Each package contains 2 bits. This part is appropriate for electricians, carpenters, plumbers, and HVAC technicians who work regularly with square-drive fasteners on the job site.

This insert bit is suited for residential and commercial installation work where square-drive screws are the fastener of choice. Square drive bits are widely used in electrical panel work, low-voltage enclosure assembly, ductwork brackets, and finish carpentry. The 1-inch insert format is compatible with magnetic bit holders and hex-shank quick-change systems found on most professional impact drivers. The 2-piece pack provides an immediate backup when the primary bit shows wear.

Installation Notes

Insert bits are installed and removed by hand from magnetic or quick-change bit holders — no tools required for bit changes. Ensure the impact driver or drill driver is powered off and the trigger is locked before changing bits. Select the correct No. 2 Square size to match the fastener recess and avoid cam-out or fastener head damage. Follow applicable trade codes when driving fasteners in electrical, plumbing, or mechanical assemblies.
