With a pro configuration of 55 pieces, this set can be used with electric wrench, impact wrench, ratchet wrench, rod bender, and other tools for automotive maintenance, equipment assembly, industrial manufacturing, power inspections, and more.

The hexagonal socket design creates a gap between the nut and the edges during operation, preventing excessive friction and wear. It can withstand greater impact force and effectively remove bolts.

Using laser etching and rolling processes, the extra-large size markings on the sockets are clear and easy to identify even under various lighting conditions. The markings are also resistant to wear.

The split-strengthened case ensures durability and is less prone to breakage. The portable design allows you to easily carry it for work on the go.
