STRONG POWERFULThe robust magnet produces a strong magnetic field; industrial magnets can attract and secure various metal objects, such as nails, screws, etc., making tasks more practical and efficient. Rust resistant and waterproofExtra strong magnets feature a triple-layer coating of Black epoxy + Nickel + Copper. This top-tier coating delivers a shiny, rust-resistant shield for the waterproof magnets. The surface uses an automotive-grade epoxy coating; the total salt spray test exceeds 72 hours, effectively resolving the rusting issue of the neodymium magnets. VERY STURABLEThese magnets for science projects, with Countersunk Hole and screws, are constructed from metal material, offering greater sturdiness and durability than plastic alternatives.

These strong craft magnets are enclosed in a steel cup and will not break under normal use, which significantly enhances the durability of the cup magnets. MULTIFUNCTIONAL USEWall magnets measure 20mm x 5.5 mm ( 0.78 x 0.2 inch), with tolerances of ± 0.2 mm x ± 0.2 mm. Rust-resistant magnets are ideally suited for use in companies, industry, scientific research, furniture, and household settings. The black magnet is ideal for black home decor and hidden installations. PROFESSIONAL SERVICEOur circle magnets are produced in accordance with ISO 9001 Quality Systems.
