Counter Bore Neodymium Magnetic Cup Assemblies
At Dura Magnetics, you get the best magnet and magnetic assembly design and engineering assistance in the marketplace.
Counter bore cup magnet assemblies are magnetic assemblies consisting of a steel cup and a neodymium magnet base containing a counter-bored, or flat-bottomed hole. This counter-bore hole provides a space for a screw to be put through the assembly and have the flat head of the screw fit flush with the magnet in the assembly, allowing for a variety of mounting options.
Dura Magnetics supplies counter bore neodymium cup magnet assemblies available in a variety of in-stock dimensions. If we do not have the size you are looking for listed below, we can also supply custom counter bore assemblies to meet your exact specifications.
