strong neodymium countersunk disc magnets are best for securely attaching magnets on to both magnetic and non-magnetic surfaces including wood, plastic, 놋쇠, 구리, rubber and aluminum.
The countersunk hole enables a standard screw to be flush mounted into the magnet to securely fasten it into doors, cabinets, 가슴, toolboxes, displays, 손짓, 패널, art frames and other hidden closure or attachment applications. Closures can involve a pair of magnets with the countersunk holes on opposing poles or one magnet and a steel disc.
Strong countersunk ring magnets sized specifically for flat-head screws. The north pole is on the side of the magnet with the large hole, where the head of the screw would be.
These countersunk rings can be used for a wide range of applications including door closures and tool hangers.
