With a professional 90-piece configuration, this set can be used with electric screwdrivers, impact wrenches, ratchet wrenches, rod bending tools and other tools for automotive maintenance, equipment assembly, industrial manufacturing, performance testing and more.

The internal hexagon design creates a gap between the nut and the edges during operation, thus preventing excessive friction and wear. The internal hexagon withstands higher impact forces and allows for efficient loosening of screws.

Thanks to the laser engraving and rolling process, the extra-large markings on the frames are clearly visible even under varying lighting conditions. The markings are also wear-resistant.

The split, reinforced case ensures durability and is less prone to breakage than traditional one-piece cases. The portable design makes it easy to take it with you for work on the go.
