Description

Block magnets with two countersunk boreholes. They can be fastened with countersunk screws. They are only 4 mm thick and therefore very inconspicuous when used to hang up signs, tools, etc. Especially well-suited for carpentry, kitchen installations, exhibition stand construction, shopfitting, signage technology, etc. We also carry round Pot magnets with counterbore screw-on.

The following screws fit into the boreholes of these magnets:
  • Slotted countersunk wood screw: DIN 97 (3,5 mm)
  • Cross recessed countersunk flat head screws (machine screw): ISO 7046-2 M3 (3 mm)
  • Countersunk torx screws/hexalobular socket (machine screw): ISO 14581 M3 (3 mm)
  • Hexagon socket countersunk flat head screws (machine screw): ISO 10642 M3 (3 mm)

Additional features and tips

Neodymium magnets are very brittle and can break or chip when exposed to repeated blows. To protect the magnets it would be best to slightly countersink them into a material (e.g. into the wood of the furniture).
