Wera Hex-Plus L-keys have a larger contact surface inside the screw recess. This reduces the notching effect and thereby also the deformation of the screw head. At the same time up to 20 % more torque can be transferred. The ball-end on the long arm enables angled access to drive screws in awkward places. L-keys with thermoplastic sleeve (SPKL) are manufactured out of easy-to-grip, circular material. The sleeve ensures that work is safe and comfortable even at low temperatures. High corrosion protection features thanks to the special BlackLaser surface treatment. The contrasting inscriptions on the color-coded sleeves mean that it is easy to recognize the correct sizes and this makes it simpler to find the right tool. The wear-resistant clip material ensures that the L-keys are securely held yet are easy to remove.
