uxcell 7mm Hex Socket Nut 310mm Long Wrench Screwdriver Hand Tool Black Green

Shipping took a while. It was shipped via USPS from China. When I purchased this hand-tool, the estimated delivery was set for mid May, but it showed up 3 or 4 weeks before its estimated delivery day. So, despite delivery taking about 3 weeks, it arrived about twice as fast as USPS estimated.The shaft on this driver is flexible. It makes it ideal for getting into tight spaces to tighten/loosen a 7mm hex nut/bolt. There is nothing else out there that meets the specs of this driver. I love it and so do the other techs and engineers that use it in our R&D Lab. For some reason, 7mm nuts are all over one of the big new products we are developing.This would be ideal for automotive type work where you need to get around hoses etc to access a 7mm nut. However, I don't know how often a 7mm nut appears under the hood of an auto.The driver is designed to be simple but effective. Has a tight, solid construction. Feels and looks like it will last forever. Super addition to our tool box at work.
