Ideal for furniture fixings, hanging artwork and keeping doors and drawers closed, countersunk magnets have a central hole which allows them to be fixed to non-magnetic surfaces with a screw. Because these magnets have a PTFE-coating they are ideal for using to attract fragile or easily marked surfaces, the PTFE coating increases friction, softens impacts and prevents marking. Countersunk magnets with opposite poles on the countersunk face can be used to attract two surfaces or two opposing countersunk magnets with the same pole on the countersunk face can be used to create a damping, shock absorbing or repelling effect. Also available with the south pole on the countersunk face. PROTECTIVE PTFE COATING. PTFE-coating they are ideal for using to attract fragile or easily marked surfaces, the PTFE coating increases friction, softens impacts, and prevents marking other surfaces. IDEAL FOR DIY & CRAFTS. Ideal for furniture fixings, hanging artwork, and keeping doors and drawers closed, countersunk magnets have a central hole that allows them to be fixed to non-magnetic surfaces with a screw. CAN BE SECURELY FIXED IN PLACE. Can be fixed in place with 6mm diameter countersunk screws. STRONG RARE EARTH MAGNET. Each magnet can support 6kg pull vertically from the magnetic face when in flush contact with a mild steel surface.
