18Pcs Magnetic Impact Nut Driver Set is made of industrial grade chromium vanadium steel, which is strong and durable, and has a black phosphate coating for corrosion resistance. An external weatherproof coating provides additional protection against damage. For example, components and materials that may come into contact with the extension rod during maintenance, such as oil and liquid, such as in the automotive field. This nut setter can be used with an impact/drill bit driver or an inner hexagonal ratchet, which can firmly grasp the hexagonal nut and fasteners for easy installation or loosening/removal. The leaflet design head fastener with rounded edges grabs the nut from the side rather than the corner to prevent peeling and extend the life.
