This set includes 1/4\", 3/8\", and 1/2\" drive ratchets, with lengths of 3.54\", 4.13\", and 5.31\" respectively. The compact design of these ratchets saves space and makes them easy to use, even for people with large hands. Our mini-ratchets exceed the ANSI standard. These stubby ratchets are made of premium chrome vanadium steel and feature a fully polished chrome-plated surface with an elegant knurled design. They are corrosion-resistant, easy to wipe clean, and non-slip. The ratchet head has a 72-tooth reversible gear that only needs a 5-degree swing arc to operate. The quick-release reversible head design allows you to change the socket by simply pressing the center part, and you can change the drive direction by flipping the bias drive switch. The ratchet wrench's quick-release head can firmly lock the socket and prevent it from accidentally falling off. The offset switch ensures that the gear engages perfectly, preventing slipping and freewheeling. The 1/4-inch ratchet is perfect for removing small screws in furniture and household appliances. The 3/8-inch drive is suitable for car repairs, motorcycles, and electric vehicles, while the 1/2-inch drive is ideal for cars and motorcycles.
