Uxcell 17mm Impact Hex Bit Socket, 3/4" Drive 98mm Length CR-MO Steel Metric Sizes

Made of high carbon steel, high strength and good wear resistance, durable to use.
To prevent rust and corrosion, the black phosphate finish absorbs and retains oil, repelling moisture.
The through-hole in the drive end locks onto the tang of impact wrenches or drivers so it won't fall off or stick on fastener heads.
It has a radius corner design, causing the socket to grasp the sturdy wall of the fastener instead of the corners, thereby reducing the wear of the fastener.
Widely used in DIY hand-making, household maintenance, and most general repairs.
