Pot Magnet

Pot magnet, also known as suction cup magnet or countersunk magnet, is assembled with high-power NdFeB magnet encapsulated inside a magnetic conductive steel shell. The steel shell concentrates magnetic flux, providing far stronger pull force than bare magnets of the same size. Built with countersunk mounting holes, it is a widely used magnetic accessory for equipment fixing, tooling positioning, sign bases and hardware adsorption.

Four Core Advantages of Pot Magnets

Concentrated Magnetic Flux & Strong Holding Force

The steel shell gathers scattered magnetic fields and focuses magnetism on the contact surface. It delivers excellent load capacity and stays firmly attached under vibration and shaking conditions.

Built-in Countersunk Holes for Easy Installation

The central countersunk hole allows bolt mounting on plastic, wood panels and metal brackets. Assembly is simple, secure and flexible for disassembly.

Steel Shell Protection Against Impact & Chipping

Fully enclosed by steel housing, the magnet resists chipping and cracking from impacts. Zinc-plated surface provides rust resistance, moisture and corrosion protection, suitable for indoor and outdoor applications.

Anti-slip Design for Precise Positioning

It fits tightly onto steel plates with outstanding lateral pull strength. Workpieces stay in position without shifting, ideal for precision tooling.

Application Range

Mechanical equipment positioning, mold jigs and fixtures, magnetic bases for advertising signs, lamp mounting, production line material holding, temporary fixing of metal parts, warehouse sign bases and more.
