This 12 point box type open-end wrench is an ultra-thin model made of chrome vanadium steel, with high hardness, strong torque, and good toughness. The surface has been electroplated to give it excellent rust and corrosion resistance.12-point design grips the fastener from all sides, providing more points of contact and reduced risk of slippage, as well as allowing for easier engagement of fasteners in tight spaces and more angles for applying torque.Combination wrenches are widely used for tightening or loosening bolts and nuts in automotive maintenance, pipeline and mechanical maintenance, as well as construction projects such as engines, chassis, pipelines, fixtures, furniture assembly, electrical maintenance, mechanical, equipment and industrial applications, and other DIY projects.
