• 【PREMIUM CR-V STEEL】BLACKROBOT 3/8” socket set made of Cr-V steel. This high-quality construction ensures that sockets will withstand even the toughest jobs, while the black phosphate surface treatment adds an extra layer of protection against wear, oxidation, and corrosion. And don't worry about rusting – we've applied a thin layer of oil to each socket to prevent any oxidation from occurring. 【MULTI-SIZE SOCKET SET】The set includes 10pcs Metric Deep Sockets (8, 10, 11, 12, 13, 14, 15, 17, 19, 22mm) and 14pcs Metric Shallow Sockets (6, 8, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 21, 22mm), as well as 9pcs Shallow Sockets (1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", 3/4") and 6pcs Deep Sockets (3/8", 7/16", 1/2", 5/8", 11/16", 3/4"). 2pcs Spark Plug Sockets (5/8", 13/16"), 1pc 6" Drive Extension Bars, 1/2"F x 3/8"M adapters, and 1pc Universal Joint, 72-Teeth Pear Head Ratchet. 【SAFETY DESIGN】The metric sockets with a 6 point contact design, the SAE sockets feature a 12 point contact design, which increases the contact area with fasteners to achieve firm grip, increase torque, reduce wear, and prevent rounding, making them versatile for a variety of fasteners. The steel ball on the tool and the hole on the socket combine to keep the two tightly interlocked to avoid accidents of the socket popping out under high-pressure tool use. 【EASY-READ SOCKET SET】Each socket has a highly visible laser-etched marking on a black phosphate finish for easy identification of the socket measurement.

It is secured by two lever metal locks, so that the socket does not fall off easily.This design allows for fast application, efficiency, and accuracy in any work space. 【SERVICE GUARANTEE】Meets or exceeds ANSI performance standards.
