Article description Set of high-quality L-keys for hexagon socket screws with high corrosion protection and extra long lever for high power transmission and working in low positions. The Hex-Plus profile offers larger contact surfaces at the screw head. The notch effect is thereby reduced to a minimum, the destruction of the screw head almost eliminated. Tools from size 3 onwards offer a holding function through a pressed resilient ball. The holding function on the long arm keeps screws securely on the tool Hex-Plus allows socket head screws to live longer Extra-long arm High corrosion protection thanks to chrome-plating Wear-resistant clip material for enhanced durability L-Keys We questioned the classic L-key design, since all too often the screw head recess is rounded out, meaning screws can no longer be tightened or loosened - and so the user finds the L-key slipping out of the recess. Wera Hex-Plus tools have a larger contact surface in the screw head. The notching effects are reduced and thereby the deformation of the screws. At the same time, as much as 20 % more torque can be applied. With retaining function on long arm The clamping of the screw is achieved by a flexible locking ball. The holding function is especially helpful in confined, hard-to-reach spaces, where there is no room for a second hand to secure the screw on the tool. Hex-Plus Hexagon screws can endure a problem because the contact surfaces delivering the power from the conventional tool, is transferred to the screw via very small surface areas. The consequence: the screw can become damaged (rounding out). Hex-Plus tools have a greater contact surface that prevents this from happening! At the same time, as much as 20 % more torque can be applied. Good to know: Hex-Plus tools fit into every standard hexagon socket screw! Size markings All L-keys are easily accessible due to their size markings. High corrosion protection thanks to chrome-plating Chrome-plated hexagon L-keys for outstanding surface protection and long service life. High corrosion protection. Secure hold and easy removal The wear-resistant clip material ensures that the L-keys are securely held yet are easy to remove.
