【Deep Well Socket】Suitable for the maintenance of various types of fasteners on the vehicle. 【Superior CR-V Steel】Constructed with heat-treated forged CR-V material, our 1/2 inch impact socket has high hardness and durability, and can withstand greater torque from impact tools. The sturdy and professional chrome vanadium alloy structure allows you to undertake different projects. 【Fastened 6-Point Design】The recessed hexagonal nut is easier to embed, which can grasp the stubborn fasteners without falling off. The 6-point lateral drive design prevents the sockets from rounding under the high torque output, making them maintain integrity without deformation. 【Durable & Laser Marking】Different from the traditional black oxide coating, BOEN deep impact socket 1/2'' dirve adopts black manganese phosphate coating to provide excellent corrosion resistance and rust resistance for long-term use. Laser markings make all model numbers easy to keep, read and quick identification. 【Quality & Service Guarantee】The deep socket meets ANSI standards. We provide 1 year quality warranty. All hex sockets have been rigorously tested to ensure the best performance and durability. If you have any questions, please feel free to contact us.
