The Wera 3950 PKL Hex-Plus L-Key are made from stainless steel to prevent the formation of extraneous rust, then vacuum ice-hardened for industrial strength. With patented Hex-Plus profiles; drives from the flats instead of the points, preventing rounding out. Allows 20% more torque to be transferred. Ball-end on the long arm for working at an angle to the screw head.
