[Features] ● Due to the special plate structure of the wrench part, nuts and bolts do not fall off. ●The bolt can be inserted sideways into a narrow space with the wrench sandwiched between them, and the bolt can be turned with a strong torque while applying pressure from above. ● The "double hex" structure of the wrench part can turn licked or rusted bolts that cannot be turned with a normal wrench. ● 80 gears enable smooth movement. ●We realize return angle of 30 degrees in small increments.
