Rubber Coated Magnets: The Scratch-Free, Heavy-Duty Magnetic Mounting Solution
Rubber coated magnets solve these problems perfectly. Built with high-grade neodymium magnetic cores and fully encapsulated in a durable rubber outer layer through precision injection molding, they retain the incredible holding power of rare-earth magnets while delivering superior surface protection, anti-slip stability, waterproofing, and corrosion resistance. Whether used on delicate machinery, automotive paint, polished metal, or in harsh outdoor conditions, they provide secure, long-lasting performance.

3M Adhesive Backed Magnets – Strong Neodymium & Rubber Magnets with 3M Double-Sided Tape for Easy Mounting
The secret to our 3M adhesive backed magnets lies in two non-negotiable components: genuine 3M double-sided tape and high-grade magnetic materials. Unlike competitors who cut corners with low-quality, off-brand adhesive, we use authentic 3M 468MP or 3M 300LSE tape—the gold standard in industrial adhesion. This isn’t the flimsy tape you find on discount magnets; it’s the same tape used in manufacturing and commercial applications, designed to bond securely to almost any smooth surface: metal, plastic, wood, glass, ceramic, and even painted walls .
