Hard ferrite pot magnets with hole and countersink, galvanized

The technical advantages of a ferrite pot magnet with a through countersunk hole

A ferrite pot magnet with a countersunk hole (also referred to as a low-profile pot magnet with a through countersunk hole) is distinguished by its flush mounting method. Thanks to the through countersunk opening, the magnet can be securely fixed into a structure using a standard metric flat-head or countersunk screw or bolt (M-size), allowing the screw head to sink completely into the magnet. The hard, ceramic ferrite magnet is encapsulated in a robust steel cup. This cup protects the magnet core against mechanical damage and simultaneously legalizes and redirects the magnetic field lines. As a result, the holding force at the active pole face is maximally concentrated upon direct contact with a steel surface.

Why countersunk ferrite pot magnets are the ideal B2B choice

For many industrial applications, ferrite possesses specific material properties that are superior to other magnet types:

• High temperature resistance: These pot magnets maintain their full magnetic performance and holding force at extreme temperatures up to 250°C. This makes them exceptionally suited for machinery building, ovens, and hot manufacturing environments.
• Corrosion resistant and maintenance-free: The ceramic material does not oxidize. The magnets are highly resistant to moisture and weathering, enabling long-term indoor and outdoor use without any loss in performance.
• Cost-effectiveness in serial production: From a pricing perspective, ferrite is highly attractive. This makes these low-profile countersunk pot magnets the perfect, budget-friendly solution for larger industrial projects.

Application areas in modern engineering

Due to the through countersunk hole, these magnets are easy to integrate flush into existing systems and structures without protruding screw heads causing obstruction. They are widely used worldwide in exhibition booth construction, shopfitting, machinery building, toolmaking, and lighting technology. Whether it concerns the blind fixing of panels, suspending fixtures, or creating strong, reusable closures: with our extensive assortment of diameters and hole sizes, SAV always offers the right magnetic solution for your specific industry or project.
