Wera 5022720001 Stainless 3950 PKL/9 Hex Key Set – 9-Piece Metric L-Keys with Clip

Overview

Discover a reliable hex key set designed to stand up to demanding tasks while staying rust-free. The Wera 3950 PKL/9 bundle is crafted from 100% stainless steel, helping to keep fasteners pristine and reducing the risk of contamination from tool metals. Through Wera’s vacuum ice-hardened process, these L-keys gain the hardness needed for industrial applications while maintaining precision across sizes. The Hex-Plus geometry preserves screw recess life by ensuring stable contact and minimizing edge wear, allowing for smoother torque transfer across many fasteners.

Lightweight yet tough, this 9-piece set is built for frequent use in workshops, garages, or mobile tool kits. A distinctive feature is the ballpoint on the long arm, which makes it easier to insert the tool into screws from an angle and in confined spaces. The stainless construction stays fixed and true after repeated removals, so you can trust the set to remain organized in busy work environments.
