Countersunk magnet 23x4 mm. (neodymium)

Countersunk magnet for a countersunk screw.

Diameter: 2,3 cm.
Height: 0,4 cm.
Screw hole: ø 4,5 mm. (M3)
Strength: approx. 6,5 kg.

Round magnet with a countersunk hole. The strength on 4 kg. is measured on a magnetic steelboard. If there is a gap between the magnet and the magnetic counterpart, the strength is weakened a lot. 

This magnetic type is not reinforced with a metal pot. You therefore need to be carefull in handling the magnet as it will break by hard shock. 

Recommened for indoor use. By constant contact with wind and weather the power magnets will rust with time. 

SPECIFICATIONS:
Strength: ca. 6.500 g.
Magnetism: N35
Coating: forniklet (Ni)

OBS! You can't use 2 of these magnets againist each other as the magnetic poles are turned the same way on all magnets. Choose instead another magnet or a metalplate as a counterpart.
