Product Description
Two jobs are covered by one small disc here: it holds by magnetism, and the screw hole lets you fix it down mechanically. The N52 Countersunk Magnets 20mm x 3mm - Strong Industrial & DIY Use (SKU MAGNET-RING-20MMX3MM) is sold for hobby, DIY and industrial work.
Reading the spec
- N52: the grade marking for a high-strength magnet.
- 20mm diameter: a disc 2cm across, compact enough for small fixings.
- 3mm thick: a low profile, so it sits close to the surface it is fixed to.
- Countersunk hole: a tapered recess in the centre. A countersunk-head screw goes through it and can sit flush with the magnet face.
Before you fix it
Check the surface before drilling. Magnets grip ferromagnetic materials such as iron and steel, or another magnet. They do not grip aluminium or plastic.
Strong magnets can snap together hard and pinch skin. Handle them one at a time and keep them apart until you are ready to fix them.
Where it fits
Use it where you want a removable, screw-fixed hold instead of relying on adhesive alone. Typical examples are workshop, hobby and general fixing jobs.
