Neodymium Block Magnet 40x20x10 mm – With Countersunk Hole (Z-pole)

Block magnet 40x20x10 mm with countersink hole | Neodymium Magnet – Z-pole

This powerful neodymium block magnet (40 x 20 x 10 mm) features a countersink hole (5.5/10.5 mm) , making it easy to mount with a flat-head screw. The Z pole (or south pole) is on the visible side, making this magnet ideal for applications where polarity is important – for example, when combining multiple magnets.

Thanks to its strong magnetic force, this magnet is perfect for both technical applications and creative projects where reliability and precise attachment are required.

Features:

• Dimensions: 40 x 20 x 10 mm

• Material: Neodymium (NdFeB), grade N45

• Countersink hole: 5.5 mm inside / 10.5 mm outside (suitable for flat head screws)

• Polarity: Z-pole on the visible side

• Magnetic force: very strong – suitable for medium to heavy loads

• Mounting: easy mounting with one screw

• Finish: Nickel plated (corrosion protection)

Applications:

• Industrial and technical installations

• Interior and furniture construction

• Creative constructions and DIY projects

• Systems where pole orientation (Z/N) is essential

Caution: Neodymium magnets are very powerful – keep them away from electronic equipment and small children.
