Strong Magnets, Perforated, Super Strong, with Screws, 16mm Diameter, Set of 10

[Exceptional Magnetic Force] This product uses super-strong magnets, with a vertical magnetic force reaching 4kg. The magnetic force is sufficient to attract metal tools such as wrenches, hammers, and knives. [Rustproof and Waterproof] Both the magnets and the metal casing are plated, preventing rust even when wet, making it suitable for outdoor use. [Easy to Use] Includes dedicated screws, eliminating the need for complicated work; it can be easily attached to walls, wooden shelves, etc. [Role of the Metal Casing] Since magnets themselves are fragile, encasing them in a metal casing prevents damage to the magnets. Furthermore, the metal casing concentrates the magnetic field lines, doubling the magnetic force. [Specifications and Warranty] 16mm diameter magnet set. 10 magnets, 10 screws.
