1. Palm ratchet wrench: This reversible thumb ratchet wrench is the best thing since the birth of the thumb! This drive ratchet set comes in 3 sizes: 1/4 inch, 3/8 inch, and 1/2 inch, which can be used in a variety of scenarios to meet your daily work needs. This is great if we don't have enough space to actually rotate the entire ratchet. 2. High-quality materials: Our finger ratchet kit is built for strength and durability. Designed for chrome vanadium steel and chrome-plated finish to extend the life of the tool. 3. The finger wheel ratchet is designed for narrow spaces where a standard ratchet can't be installed. So we can put this thumb roller here. It will be much easier to use. Each tool in this ratchet set comes with a directional thumb lever with a non-slip roller handle for better performance. 4. Flexible reverse gear: The forward/reverse lever makes it easier to tighten and loosen nuts. 5. Wide Application: This small ratchet kit is very suitable for home maintenance and all car repairs, such as clocks, drive wheels, etc...<br><br>Name:Ratchet Socket Wrench Size: 1/4 inch drive 38.5x30x6mm(1.52x1.18x0.24in) 3/8 inch drive 38.5x32x9mm(1.52x1.26x0.35in) 1/2 inch drive 38.5x39x12.5mm(1.52x1.54x0.49in) Gear Drive:1/4 Drive 43 Teeth, 3/8 Drive 39 Teeth 1/2 Drive 45 Teeth Colour:As Shown Material:Aluminum Alloy+Steel<br><br>Package Contents: 1 set * Mini ratchet wrench<br><br>Only the above package content, other products are not included.
