Heavy Duty Stainless Internal Thread Pot Magnet D40x25mm | Pull 40KG

Heavy Duty Stainless Steel Internal Thread Pot Magnet – D40mm x 25mm | 40kg Pull Force

The Heavy Duty Stainless Steel Internal Thread Pot Magnet – Ø40mm x 25mm | 40kg Pull Force is a high-performance magnetic mounting solution engineered for demanding industrial, commercial, marine, and outdoor applications. Featuring a powerful rare earth neodymium magnet housed within a corrosion-resistant stainless steel cup, this pot magnet delivers an impressive 40kg maximum pull force while offering outstanding durability in harsh environments.

Measuring 40mm in diameter and 25mm in overall height, this heavy-duty magnetic assembly incorporates a female internal threaded mounting hole, allowing it to be securely fitted with bolts, threaded studs, eye bolts, hooks, handles, or custom hardware. The stainless steel housing not only protects the magnet from impact and wear but also focuses the magnetic field onto the contact surface, significantly increasing holding strength compared to a standard neodymium magnet of similar size.

Designed for professional applications where corrosion resistance is essential, this stainless steel pot magnet is well suited to marine environments, food processing facilities, laboratories, pharmaceutical manufacturing, commercial kitchens, warehouses, engineering workshops, and outdoor installations. Its robust construction provides reliable performance while resisting rust, moisture, and general environmental exposure.

Whether you're creating removable fixtures, magnetic clamps, access panels, signage, display systems, lifting attachments, or industrial holding devices, the Ø40mm x 25mm Heavy Duty Stainless Steel Internal Thread Pot Magnet delivers exceptional holding power, durability, and mounting versatility.

Why Choose a Stainless Steel Internal Thread Pot Magnet?

Unlike standard exposed neodymium magnets, this stainless steel pot magnet combines exceptional magnetic strength with long-term durability. The stainless steel cup protects the magnet from physical damage while directing the magnetic field toward the working face, creating substantially greater holding force than an uncovered magnet.

The female threaded mounting hole provides outstanding flexibility, allowing a wide range of threaded accessories—including bolts, hooks, eye bolts, handles, and custom fixtures—to be attached securely. This makes the magnet ideal for removable assemblies, magnetic clamping systems, lifting applications, and custom engineering projects.

Its corrosion-resistant stainless steel construction makes it particularly suitable for environments where ordinary steel magnets may rust or deteriorate. Whether exposed to humidity, regular washdowns, or outdoor conditions, this pot magnet is designed to deliver reliable performance and a long service life.

Please Note

The stated 40kg pull force is measured under ideal laboratory conditions using direct contact with a clean, thick, flat mild steel plate and a straight vertical pull. Actual holding strength will vary depending on the thickness and condition of the steel surface, air gaps, paint, coatings, alignment, temperature, and the direction of the applied load.

Neodymium magnets are extremely powerful and can snap together unexpectedly, causing injury or damage if handled carelessly. Keep fingers clear during installation and use appropriate personal protective equipment where necessary.

This product should be kept away from pacemakers, sensitive electronic devices, magnetic storage media, and precision instruments. Although the stainless steel housing provides excellent corrosion resistance, prolonged exposure to highly aggressive chemicals or saltwater without appropriate maintenance may reduce the lifespan of the assembly over time.
