2Pcs 17Mm Combination Wrench Thin Metric 12-Point Box And Open End Spanner

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. Box end use: When a firm grip is required on fasteners, use the box end for higher torque applications. Open end use: In narrow spaces where the box end cannot be effectively used, use the open end to quickly rotate. Please choose the correct size wrench to tightly adhere to the fastener to prevent slipping and avoid damaging the fastener.
