Our open-end wrench is made of carbon steel with high hardness and excellent wear resistance. The galvanized finish creates a protective zinc layer that provides rust and corrosion resistance, ensuring long-term durability even in humid or outdoor environments.Super thin single open end wrench features an ultra-thin jaw design that enables access to confined spaces like crowded engine compartments or densely packed mechanical setups, reducing clearance interference for easy fastener engagement in tight gaps while maintaining reliable torque transmission, thus enhancing maneuverability in narrow areas for efficient tightening and loosening tasks.Mainly used to tighten or loosen nuts and bolts with flat sides, especially when a socket wrench or adjustable wrench cannot reach them due to space constraints.
