26.4mm diameter x 6.2mm thick x 6.2mm diameter countersunk hole.
1.04 in. diameter x 0.24 in. thick x 0.24 in. diameter countersunk hole.
Each magnet's north and south pole are on opposite 26.4mm (1.04 in.) diameter faces.
Each magnet can support a steel weight of up to 6kg (13.23lbs) vertically from the magnetic face when in flush contact with a mild steel surface.
Excellent resistance to demagnetisation.
Fully coated with PTFE coating to provide a water-resistant finish.

These Neodymium countersunk disc magnets produce an astonishing pull of 6kg (13.23lbs), remarkable for a relatively small magnet. Every magnet is fully coated with PTFE which makes them completely waterproof and ideal for outdoor use or applications where the magnet may come into direct contact with water. What's more, because of their resistance to demagnetisation they are ideal for creating a shock-absorbing or damping effect when used to repel other magnets. These magnets come with a safe-handling warning; because they are so powerful they can be dangerous if not handled carefully.

Always room for improvement, even with a good product

This magnet was one of three different styles that I had purchased of similar size, but the same style. The other two were of a cheaper variety, they were not plastic clad and smashed themselves to pieces before long.

From those false starts was where I got the idea to opt for a plastic coated one, it made so much sense. Indeed, now in my possession, it is far more robust, performing as imagined and I am happy with it.

However, I cannot ignore the fact that the plastic used, although also available in black, is white and that it for a reason. The issue I have is that the top face of the magnet (with the widest surface area) allows the dark internal magnet to show through, is semi-transparent in appearance and not opaque, as in the imagery provided here on the website. I think Neodymium magnets would be strong enough to perform with a few more microns thicker plastic case to suitably disguise its internal magnet so it were to appear all white, this after all is a key feature of the product - its colour.

Following on from this I would also recommend that a white coloured screw be included with this magnet as it's likely to be used as a display piece. Failing that, if costs are too high, then a fitted matching white plastic cap for a philips screw included, giving a more seamless finish.

The added cost of these improvements would be minimal and save the customer a lot of time themselves. After all, the packing issued in order to ensure safe delivery was par-excellence, so why not go the extra mile with the final product as well?
