Milwaukee SHOCKWAVE Impact Duty 5/16" x 6" Magnetic Nut Driver 49-66-4687
ELIMINATE FASTENER DROPS
In high-cycle fastening environments, the weak point in your drivetrain shouldn't be the magnet. The Milwaukee SHOCKWAVE Impact Duty™ 5/16" x 6" Magnetic Nut Driver is engineered with a proprietary CUSTOM ALLOY76™ heat treatment that balances hardness and flexibility to survive the high-torque impulses of modern 1/4" hex impact drivers. By integrating an optimized SHOCK ZONE™ into the shank, this accessory absorbs peak torque that would otherwise shatter standard carbon steel bits, while the industrial-strength magnet remains seated even after thousands of cycles.
- / SHOCK ZONE™ Geometry: Precision-engineered to flex under stress, significantly reducing the frequency of bit failure in heavy-duty impact applications.
- / Persistent Magnetism: The Impact Duty™ magnet is specifically designed to resist loosening, ensuring unyielding fastener retention for overhead work.
- / Chamfered Engagement: Features a refined internal hex geometry and chamfered edge to provide a dead-on fit, virtually eliminating screw-head stripping.
- / 6-Inch Reach: Provides the necessary clearance for tight-access applications without sacrificing the structural integrity of the drive shank.
- / Color-Coded ID: High-visibility bands allow for rapid size identification in a crowded tool bag or drawer, streamlining your workflow.
