Description
Irwin IWAF34338B10 Impact Mag Chuck 3/8" Long
Heavy-Duty Impact Rated. Industrial Rare-Earth Magnet. Extended Clearance Reach.
The Irwin IWAF34338B10 3/8" Magnetic Impact Chuck brings industrial-grade endurance and slip-free security directly to high-torque fastening tasks. Precision-machined from premium, high-strength tool steel, this heavy-duty nutsetter is custom-built to handle the violent rotational impact forces delivered by modern 18V and 20V brushless impact drivers. It provides commercial metal builders, HVAC installers, ductwork specialists, and general building contractors with the unyielding strength required to sink self-tapping hex screws and structural fasteners continuously without shearing the bit core or rounding off screw corners.
Maximum fastener retention and deep access capability define the layout of this premium drive socket. The IWAF34338B10 is equipped with an industrial-grade rare-earth magnetic insert, which provides a powerful hold on hex head screws. This allows tradespeople to confidently load fasteners one-handed and drive them at awkward angles without the risk of dropping or losing expensive hardware down wall studs or engine bays. Built with an extended long-reach shank profile, it snakes into recessed channels, tight bracket assemblies, and deep equipment corners where standard stubby nutsetters cannot reach. Complete with a universal 1/4-inch quick-change hex shank, it locks securely into all standard impact drivers, chuck adapters, and extension bars.
Why the Irwin IWAF34338B10 3/8" Long Impact Chuck Rules the Bit Case:
- True Impact-Rated Geometry: Forged from optimized tool steel to absorb high-torque spikes, preventing fracture failures and extending tool lifespan.
- Ultra-Strong Rare-Earth Magnet: High-retention magnetic core holds hex fasteners tightly in place for seamless, efficient overhead work.
- Extended Long-Reach Profile: Deep shank length gives you the required physical clearance to bypass obstructing brackets and tight frame boundaries.
- Lobular Drive Architecture: Specialized internal hex corners push against the flat sides of the fastener rather than the corners, dramatically reducing screw rounding.
- Universal 1/4" Quick-Change Shank: Standardized hex base snaps instantly into quick-release impact driver collets, drill chucks, and magnetic bit holders.
