BulletPoint2 : Material - The flare nut crowfoot wrench is made of the preferred 40Cr steel, which has high hardness, strength and good wear resistance, able to withstand greater torque and pressure without deformation or damage. It adopts a surface treatment of chrome plating, with a smooth and flat surface without burrs, enhancement rust and corrosion resistance, strong and durable, suitable for various working environments. BulletPoint3 : Feature - Rounded head design of the open-end wrench eliminates any stripping or splitting of the wrench and ensures a snug fit on fasteners, helping to get the job done efficiently. The corresponding size is engraved on each wrench in clear fonts for easy identification. BulletPoint4 : Application - Widely used for hard-to-reach fasteners that ordinary open-end wrenches cannot reach, they are connected to drive ratchets, extension rods or torque wrenches and are suitable for work in tight spaces, such as narrow engine areas in cars, mechanical equipment, and hard-to-reach areas under sinks. BulletPoint5 : Notice - To achieve better working results, please select a crowfoot wrench of the corresponding size and ensure that the set matches the tool. Install the selected crowfoot wrench head correctly on the wrench handle and ensure that it is firmly installed to avoid loosening or falling off during use. Maintain a stable connection between the crowfoot wrench and the workpiece during use to avoid slipping or deflection that may cause damage.
