The set includes 8 metric double-ended wrenches with sizes of: 5.5x7; 8x10; 9x11; 12x14; 14x17; 17x19; 19x21; 24x27mm. The parts are silver-white in color, made with high precision from CrV alloy steel, high durability, and rust-free during use. The wrench is designed with a matte handle to help create good friction between the user's hand and the wrench, avoiding slipping during use. The wrench has two lug ends to help disassemble parts faster. Both wrench heads are designed at a 75° angle, making it extremely easy to screw and unscrew bolts in recesses and grooves.
