The sleeve is forged with high-quality vanadium steel and quenched as a whole. The hardness value can reach 55-60. The special arc inner angle thin-wall design makes the contact surface between the sleeve head and the nut edge contact: increase the torque by 15%, make the nut easier to tighten or open, and increase the service life of the nut. The utility model can effectively reduce the wear of the sharp angle of the nut, prevent the operation from slipping, and is more safe.
Surface mirror, knurling double treatment, more beautiful design, strong corrosion resistance, not easy to rust, prolong the service life of sleeve.
High quality V-Cr steel socket, durable and long service life.
Chromium plating and anticorrosive surface treatment.
High hardness and torsional strength, fully compliant with ISO / ANSI standards.
For impact controller and socket wrench.
