Ø20x9/4.2x4 mm Countersunk Neodymium Magnet – Strong Mounting and Versatile Use

Countersunk Neodymium Magnet – Easy Mounting on Wood, Plastic, or Concrete Surfaces

This high-strength neodymium magnet features a specially engineered countersunk hole, allowing you to fasten it securely with a screw or bolt. Designed for non-metal surfaces, it provides a practical and stable magnetic mounting solution for wood, plastic, concrete, and similar materials.

Thanks to its special design, it enables easy installation in a wide range of applications where standard magnets are not suitable. The unique structure allows seamless integration without sacrificing magnetic performance.

Note: Overtightening the screw may cause the magnet to crack. Please proceed with care during installation.
