• A pack of 1, 4, 20 or 40 magnets.
• 50mm x 50mm x 25mm thick with a 8.2mm diameter countersunk hole on either side for fixing.
• 1.97 in. x 1.97 in. x 0.98 in. thick with a 0.32 in. diameter countersunk hole on either side for fixing.

• Super-strong 95kg (209.48lbs) Pull.
• Each magnet is countersunk on either side, the north pole of each magnet is identified by a dimple on the surface.

This magnet is little larger than a block of post-it notes but incredibly produces an astonishing pull of 95kg (209.48lbs) (209.48lbs). A single F335NS is so strong that it will wipe data from hard drives and is commonly used in large scale engineering projects such as wind turbines. Each magnet has a triple coating of nickel, copper and nickel again to reduce corrosion. These magnets come with the convenience of a countersunk hole, meaning they can be screwed into place. Countersunk magnets with opposite facing poles can be used to attract two surfaces, or two opposing countersunk magnets with the same poles facing can be used to create a damping, shock absorbing or repelling effect. This is one of the strongest countersunk magnets available on the market.

Please note, these magnets should only be handled by people who are used to handling strong magnets and once a thorough risk assessment has been undertaken as they will easily crush trapped fingers causing serious injury.
