Our range of Heavy-Duty Pot Magnets is engineered for situations where standard magnets simply aren't strong enough. By encasing a premium Neodymium (NdFeB) magnetic core within a solid, precision-machined steel shell, the magnetic field is intensely focused onto the active face. This not only amplifies the vertical pull-off force to massive levels but also protects the brittle magnet from cracking under heavy impact. This specific range features two highly specialized mounting solutions: 1. The Industrial Heavyweight (D100 x 25mm) Designed for extreme industrial applications, this massive 100mm diameter pot magnet delivers an astonishing 450kg of vertical holding force. It features a central internal threaded hole, making it the ultimate anchor point. You can easily screw in heavy-duty eyebolts, lifting hooks, or mount it directly to heavy machinery and structural steel frameworks. 2. The Flush-Mount Fastener (D40 x 8mm) Perfect for permanent surface mounting, this 40mm diameter magnet features a countersunk central hole. This design allows a standard flat-head screw to sit perfectly flush with the surface of the magnet, ensuring zero obstruction when making contact with the steel target. Despite its compact 8mm profile, it delivers a very strong 45kg pull force, ideal for holding heavy doors, building custom jigs, or mounting workshop fixtures. Key Benefits:- Extreme Force: Up to 450kg of pull power for heavy-duty industrial requirements.
- Versatile Mounting: Choose between internal threading for bolts/hooks, or a countersunk hole for flush screw mounting.
- Maximum Protection: The robust steel casing protects the neodymium core from damage and daily wear.
- Corrosion Resistant: Zinc/Nickel-coated housing ensures longevity in tough environments.

Applications
- Heavy Industrial Rigging (D100): Creating temporary but immensely strong lifting or anchor points on steel girders.
- Machinery Mounting (D100): Securing heavy equipment or sensors without the need to weld or drill into structural elements.
- Jigs & Fixtures (D40): Creating reliable, low-profile hold-down points on welding or woodworking tables.
- Heavy-Duty Cabinetry (D40): Acting as hidden, high-strength door latches for heavy steel or security doors.
