This 73-piece set includes a magnetic ratcheting wrench and precision screwdriver bits, suitable for various household repairs and electronic devices. The precision screwdriver bits are non-magnetic for delicate instruments like watches and smartphones, while other bits are magnetic for larger appliances such as air conditioners and TVs. The wrench features three driver settings: clockwise ratcheting, counter-clockwise ratcheting, and a locked position. Its free-spinning base allows for easy turning and consistent pressure. Crafted from heat-treated chrome vanadium steel with a corrosion-resistant finish, it ensures durability and strength. The non-slip handle provides a comfortable and secure grip. A plastic storage case with designated compartments for the driver, sockets, and bits is included. Dimensions: 20.1 x 11.6 x 3.6 cm (LxWxH). Note: Precision screwdriver bits are intended for small electronic devices and should not be used on screws requiring high torque. Weight: 1.38 pounds.
