Neosmuk Magnets with Hole, 10kg: Heavy-Duty Round Cup Magnets for Walls and Tool Racks (Pack of 10)
Product description
What this is
Neosmuk’s magnets with a hole are round cup magnets designed to be bolted to non-metallic surfaces using the screws provided. Each magnet claims a 10kg attractive force on thick steel, with a 17mm ground base diameter and 6mm length, and a central 3.5mm hole for easy mounting. The finish features a three-layer nickel+copper+nickel coating for corrosion resistance and a mirrored, smooth surface.
How it’s used

The magnets are intended for applications like mounting tools on a rack, securing items to a wood desk or cabinet door, or acting as a door latch. Installation is straightforward: align on a non-metallic surface and fix with the included self-tapping screws. The packaging specifies that these are permanent heavy-duty magnets, with magnetism designed to last.
What stands out on paper


On the surface, the combination of a strong neodymium magnet with a hole for mounting and a robust heavy-duty finish makes these magnets versatile for DIY and workshop setups. The hole in the centre enables flush mounting on wood or plastic surfaces, and the three-layer plating is aimed at reducing rust and wear, which is useful in workshop environments.

What to watch out for
If your project involves surfaces other than thick steel, the 10kg pull force may not translate perfectly. The claim of 10kg attractive force is specified for thick steel, performance can vary with thinner or non-ferrous materials. As with any neodymium magnet, care is needed around sensitive electronics and devices that could be affected by strong magnetic fields. The product relies on screws for secure mounting, so a surface that accepts screws reliably is important.
Who it’s for

This set should suit hobbyists, carpenters, or home-improvement users looking to organise a workshop or a garage. If you need a discreet, mountable magnetic anchor for tool racks or cabinet latches, these could be a pragmatic option.


Who it isn’t ideal for
If you primarily need magnetism on metal surfaces or lighter holdings, these may feel over-specified. For applications requiring frequent removal and repositioning, a magnetic clip or hook might be more convenient than a fixed bolt-on magnet.

Before you buy
- Confirm the surface you plan to attach to can accept screws and is thick enough to provide a solid grip.
- Check that the centre hole aligns with your mounting hardware and that you have the appropriate driver for the screws supplied.
- Consider the working environment, the three-layer coating helps with corrosion resistance, but prolonged exposure to harsh elements could still affect longevity.
Practical use case



Imagine mounting a set of screwdrivers and chisels on a wooden pegboard or cabinet door in a workshop. The flat face helps keep tools aligned, and the hole allows secure, semi-permanent placement without relying on adhesive magnets that might lose grip over time.
How it compares in approach
If you’re choosing between a simple adhesive-backed magnet and a bolt-on cup magnet, the Neosmuk option forgives a bit more permanence and load handling, provided you’re mounting on a surface that accepts screws. It’s a sensible middle-ground for those who need reliable, hard-wearing tool storage but don’t want to complicate installation with metal-to-metal fixtures.

Final decision: Should you buy it?
Should you buy it? Worth considering if you need a sturdy, screw-mounted magnet solution for wood or similar non-metallic surfaces and you’re planning to store or secure heavier tools. It suits buyers prioritising durability and a neat, flush installation, provided you can accommodate screws and the mounting surface is compatible.
