Uxcell 3/8Inch Drive x 0.28" Impact Hex Bit Socket, Metric 2.36" Length, Chrome Molybdenum 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, automotive repairs, household maintenance, and most general repairs.
