This Diymag set features a "pot magnet" design, where a steel casing redirects the magnetic field to a single face to maximize the holding power. The 16mm base is designed for high-density placement, making these hooks ideal for organizing lockers, tool chests, or utility rooms where space is at a premium. The triple-layer nickel-copper-nickel coating is intended to provide durability in active workshop environments.
Practical safety features include a threaded M4 eyelet that allows for secure attachment of various items. While the magnets are built to handle daily household use, the internal neodymium is a ceramic-style material. To ensure the longest life for the product, it is best to place the hook onto a surface gently rather than letting it "snap" on with high force, which helps prevent the internal magnet from cracking.
Tests show that the effective hold is strongest on thick, iron-rich metal. On thinner surfaces, such as the side of a budget filing cabinet, the magnetic field may not fully engage, leading to a lower weight limit. For vertical applications, adding a small rubber washer to the base can significantly increase the grip and prevent the hook from sliding under load.
For a different take on kitchen organization that accommodates paper rolls, the magnetic paper towel holder uses similar magnetic principles for a specialized task.
You can see how these heavy-duty options compare to others in the magnetic clips and hooks department.
