This is an item I purchased on Mercari. I used it only once to achieve my goal, and now I'm selling it because I no longer need it. Some of the photos are referenced from the original seller, and the last three are photos of the actual item. It has been used once, so there are hammer marks on the base (see photos). ● Description You can remove stripped screws, rusted bolts, seized nuts, broken bolts, screws, etc., by hammering. By hammering, the impact is converted into a strong rotational force, which, combined with the impact, loosens hard, stuck screws, etc. ● Product Details Shock driver body Bit holder Phillips bits: 3 Flathead bits: 3 Dedicated case *Hammer not included - Set contents: 6-piece set - Type: Shock driver - Application: Loosening stuck screws and bolts - How to use: Loosen by hammering Thank you!
