1/2-Inch Drive x 10mm Impact Hex Bit Metal Socket, Metric 3″ Length, Cr-Mo Steel

* Made of high-grade Chrome-Moly steel for strengthen and durable to use.
* To protect against rust and corrosion, the black phosphate finish absorbs and holds oil, repelling moisture.
* Sockets designed with a pin hole for use with pin and O-ring systems for secure socket retention.
* It features a radius corner design, causing the socket to grab the sturdy wall of the fastener instead of grabbing the corners, resulting in less wear on the fastener.
* Wide application in DIY hand-making, household maintenance, and most general repairs.
