Features: When you grab the "twist", all you have to do is let go and continue tightening or loosening, unlike the lifetime wrenches that need to be adjusted from time to time. They have a narrow head design for space-limited applications and SAE laser marking and metric scaled jaws for easy bra sizing. Two bolts were fully twisted with other wrenches and with the teeth and handle of this wrench, it was possible to loosen them. Almost no force required even on completely round nuts. Multifunctional design, can be used as a wrench or pipe wrench, easy home repair, outdoor maintenance, engineering maintenance, mechanical maintenance, etc. Specification: Material: Chrome Vanadium Steel + TPR Large Wrench: 280mm (23-32mm) Small Wrench: 220mm (9-15mm and 16-22mm) Surface Treatment: Chrome Polishing Package Included: 2 x Adjustable Wrench 1 x Multi-Language Card
