Wera's hose-covered L-shaped wrench for inch-sized internal hex screws protects your fingers. This design provides an ergonomic and comfortable grip, even in low temperatures. The Hex Plus profile offers larger contact surfaces in the screw head, minimizing the notch effect and nearly eliminating damage to the screw head. The ball on the long arm allows for safe working even in difficult installation positions. The BlackLaser surface treatment ensures excellent surface protection against corrosion and extends the tool's lifespan. The laser-etched, wear-resistant size markings on the wrench allow for quick access.
