Build a compact magnetic mounting point with this 3/4" x 1/8" N42 neodymium countersunk magnet. Its center hole accommodates a #4 flat head screw, allowing you to fasten the magnet to wood, plastic, or other suitable materials.

This rare earth disc magnet is a practical choice for magnetic cabinet closures, removable panels, display fixtures, woodworking, and DIY projects. Its slim 1/8-inch profile fits applications where space is limited, while N42 neodymium provides strong magnetic attraction.

A Nickel-Copper-Nickel coating helps protect the magnet against corrosion and provides a smooth silver finish. Magnetization through the thickness places the north and south poles on the two flat faces.

    Amazingly powerful little magnets, they actually implode on each other if you aren't careful handling them I definitely wouldn't allow children under 10 or so to play with them unsupervised.These might be too powerful depending on your application, if you are just hanging something with a magnet you'll fight to remove these. For keeping doors/drawers closed they are perfect especially if you don't allow the magnet to touch the washer or whatever it is anchoring to.

    I am using these to do 'quick attach' ways covers for my desktop mills and lathes. 5 of these on each end is enough to hold the covers in place for me. For their size, these are very strong. Dont let little kids play with these. They are small enough that they could easily be swallowed.Whats really nice is that because these are so small, they can be counter sunk into different materials easily, like plexiglass and similar products. They also have a counter sunk screw hole if you want to use these for like cabinets and such.

    Took a few tries, but finally found the magnets I was looking for on Amazon. Carefully packed. Very strong. Includes plastic separators. Haven't seen ones of this quality in over 10 years. Unlike the cup magnets which are one-sided, these attract on both sides.
