Countersunk rings with a 1/8" hole and 90 degree taper. This means that the large hole is 1/4" in diameter.

These rings are sold by the pair. One will have the north pole on the side with the large end of the hole and one will have the south pole on that side, so they will attract each other when they are screwed in.

These countersunk rings can be used for a wide range of applications including door closures and tool hangers.
