Wera 05022720001 Metric Ball End Hex-Plus L-Key Set, 9-Piece
The Wera 05022720001 (Model 3950/9) is a professional-grade, 9-piece metric L-key set designed specifically for fastening stainless steel screws while preventing extraneous rust formation. Engineered with Wera's Hex-Plus profile, these tools provide a larger contact surface within the screw head. This minimizes the notching effect, reducing the risk of rounding out the screw recess and allowing the application of up to 20% more torque compared to conventional hex profiles.
The long arm of each L-key features a hexagonal ballpoint end, enabling the tool axis to pivot relative to the screw axis. This allows for efficient "around-the-corner" screwdriving in confined spaces such as densely packed equipment racks, termination enclosures, and complex mechanical assemblies.
