The E-type plum star-shaped female sleeve is made of chrome vanadium steel (50BV30). After double quenching treatment, the hardness is enhanced, the strength and toughness are balanced, the bearing capacity of the parts is improved, and the parts are wear-resistant and less prone to deformation. The nickel bottom layer provides good anti-corrosion protection, and the surface is chrome-plated, smooth and shiny, which helps prevent rust and extend the service life of the surface. Female E torx star socket adopts a 6-point spline structure, which can better insert smoothly onto fasteners with precision chamfered ends, providing a stronger grip when in use, preventing the fastener from becoming round, and not easily slipping, improving operational safety and work efficiency. E-Torx sockets are designed to effectively tighten or remove Torx screws and bolts when repairing the body, interior frames, and electrical sensors, suitable for automobiles, motorcycles, bicycles, lawn equipment, professional machinery, home maintenance, DIY crafts, etc. Make sure the selected socket size matches the head of the screw or nut to avoid slippage or damage due to size mismatch; when using a socket tool to tighten or remove screws, apply uniform and appropriate force to avoid excessive force that may cause damage to the socket or thread.
