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.
