Wera Stainless 3950 PKL L-key Hex Metric: 2.0mm Length: 101mm (4") Wera's stainless steel is vacuum ice-hardened, giving them the hardness and strength necessary for any industrial application. Stainless steel looks great when it's done right. Sometimes people forget to use stainless tools to install the screws, and particles are left behind causing what's known as extraneous rust. Wera's Hex-Plus design helps to keep the screw head in tact with narrow contact surfaces. Standard hex designs tend to round out the screw head. The short arm is Hex-Plus and the long arm is ball end hex. Manufacturer Part #: 05022701001
