My go-to
These little buggers are so handy - compact and strong, and countersunk for screw or bolt to mount them. Good prices and fast shipping from Frenergy as always.

This Neodymium Countersunk Holder Magnet has an outside diameter of 20mm, with a thickness of 7mm and an M4.5 compatible countersunk hole. This Rare Earth countersunk pot magnet has a holding force of 6kgs.
Tradespeople and Fabricators love these magnets because they come in a range of sizes and strengths to suit a myriad of applications. The strength of the Neodymium magnet, the strongest permanent magnets commercially available, is matched by the quality materials and construction of these pot magnets. The powerful Rare Earth magnet is encased in a steel housing, lending this design enhanced durability at the same time as the steel cup serves to augment the strength of the enclosed magnet.
The Countersunk Hole allows uncomplicated attachment to almost any material such as wood, plastic, masonry and timber. The pot is simple to attach with a flat head screw, creating a flush and seamless professional finish. These magnets can also be recessed into the substrate and secured with a countersunk screw for a permanent result.
IMPORTANT NOTES:
Magnets rated holding force is when contacted directly against mild steel 3mm thick or greater.
The theoretical holding force described is for horizontal holding (based on a min 3mm thick steel surface). If you position the magnet to the vertical, you should divide the holding force amount by 3. This is due to the influences of gravity and reduced friction.
AVOID:
Please note that magnetic strength will be weaker if the item you are attaching to is alloy, stainless steel, Colourbond steel, painted, oily, rusty or bumpy.
Also, if the ferrous item you are attaching to is thin, the magnet will be weaker too, i.e. foil or sheet metal
If something in between the magnets and the surface you are attaching to (i.e fabric), the pull strength also will be lesser.

The Pull Force listed for each magnet is based on lifting 10mm thick steel vertically. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around 30% of the pull force listed due to the effects of gravity and the lack of traction between the surface and the shiny magnet.
