Wera Joker Metric Combination Wrench Set, 4 Pieces is designed to deliver exceptional fastening performance in nearly every situation with speed and precision. This set includes four metric sizes: 10mm, 13mm, 17mm, and 19mm combination Joker wrenches, each crafted to provide a secure grip and superior handling. The ratcheting ring end features an 80-tooth fine-tooth mechanism, allowing for greater flexibility even in tight spaces. Made from high-performance chrome-molybdenum steel with a nickel-chrome coating, these wrenches extended service life, excellent wear resistance, and strong corrosion protection. The Joker’s innovative fastener holding function securely grips nuts and bolts in the jaw, making positioning and fastening quick and safe with a special stop-plate that holds the fastener firmly. Its integrated limit-stop prevents slipping off the fastener head, eliminating the need for a thumb as a depth stop and enhancing safety with an anti-slip effect. The clever double-hex geometry ensures a fit and positive connection with fasteners, while the exchangeable hardened metal gripping plate bites into bolts to prevent slipping, even under high torque. With a very small 30-degree return angle, the Joker wrenches excel in confined spaces where conventional wrenches require more frequent repositioning. This unique design reduces the effort needed to tighten or loosen nuts and bolts, making the set an indispensable tool for professionals and DIY enthusiasts alike. Model Number: 05073290001
