Pull Force: 77 kg
Weight: 0.1 kg
The D42 Pot Magnet - 77kg Pull is a professional-grade magnet rated at 77 kg pull force, designed for commercial and industrial applications. Built with marine-grade materials for reliable performance in harsh environments.
The DM-PM-42 Pot Magnet is a compact high-strength clamping magnet designed to deliver impressive holding power relative to its size. Combining the performance of Neodymium (NdFeB N42) with the practicality of an M6 eye nut, it provides a reliable attachment point for securing tools, equipment, or components to steel surfaces.
With a 42 mm diameter magnetic face, the magnet can support up to 77 kg vertically when in flush contact with a mild steel surface of equal thickness. The neodymium magnet is embedded within a steel pot, concentrating the magnetic field to significantly increase the holding force. A Teflon coating enhances durability and corrosion resistance, making it suitable for demanding environments.

Frequently Asked Questions
What is the actual pull force of the D42 Pot Magnet - 77kg Pull underwater?
The D42 Pot Magnet - 77kg Pull is rated at 77 kg on a clean, flat, mild steel surface. Underwater, real-world pull force depends on surface condition (rust, paint, marine growth), surface thickness, and contact angle. Expect 50–80% of rated pull on typical subsea steel structures. Always use a 2–3× safety factor for dynamic loads.
How long will the D42 Pot Magnet - 77kg Pull last in saltwater?
With proper care — rinsing with fresh water after each use and drying before storage — the Epoxy-HDPE coating protects the neodymium core for 4+ years of regular commercial diving use. The 316 stainless steel hardware is highly resistant to saltwater corrosion. Avoid dropping the magnet on hard surfaces, as impact damage to the coating is the primary cause of premature corrosion.
Is the D42 Pot Magnet - 77kg Pull strong enough for commercial diving?
Yes. The D42 Pot Magnet - 77kg Pull at 77 kg pull force is designed for light-duty commercial work including inspections, surveys, and small tool holding. If you regularly work with heavier tools or in strong currents, consider stepping up to a higher-rated model.
What surfaces does the D42 Pot Magnet - 77kg Pull work on?
The D42 Pot Magnet - 77kg Pull works on any ferromagnetic surface — mild steel, carbon steel, cast iron, and structural steel provide the best results. Performance is reduced on rusty, painted, or curved surfaces. It will not work on aluminium, brass, copper, most stainless steels (304/316), concrete, wood, or plastic.
Can I use the D42 Pot Magnet - 77kg Pull for lifting?
No. The D42 Pot Magnet - 77kg Pull is designed for horizontal tool holding and equipment staging — not for vertical lifting or rigging. It is not certified lifting gear. For safety-critical applications, always use rated lifting equipment. The magnet is a positioning and holding tool, not a load-bearing device.
