4 Pack Neodymium Cup Magnets 30 Lb Holding Force Countersunk

Maximize organization and mounting versatility with this 4-pack of high-strength neodymium cup magnets. Engineered for a compact profile and exceptional holding power, each magnet delivers a strong 30 lb grip on ferrous surfaces, enabling secure tool storage, fixture mounting, and reliable magnetic bases for lamps, clocks, machines, and more — in kitchens, workshops, laboratories, offices, and garages.

Powerful 30 lb Holding Power

Each cup magnet delivers up to 30 lb of holding force on steel surfaces when fully engaged. The strong neodymium core is encased in a protective steel shell to minimize chipping and ensure consistent performance. The magnetic energy concentrates on one working face for a focused, repeatable grip, while the other three sides stay largely non-magnetic to reduce stray attraction.

Smart Cup Design for Maximum Hold

Round pot design with a steel shell concentrates the magnetic field onto the mounting face. This construction helps deliver higher holding power per size and reduces movement in everyday use, making it ideal for reliable, repeated mounting and easy removal.

Rugged Durability & Construction

Protected by a sturdy steel shell, the magnets resist impact and wear. The magnets are permanent, offering long service life with repeated mounting and removal, while maintaining strong, dependable performance over time.

Heavy-Duty Mounting & Quick Install

Each magnet includes a heavy-duty countersunk mounting hole and comes with stainless steel screws for clean, flush installation on metal panels, tool boards, cabinets, and more. The included hardware enables fast, secure setup with a professional finish.
