  • Product Detail
  • Technical Specifications
Permanent magnets encased with pot shape steel shells are named cup magnets or pot magnets.According to different magnetic materials,cup (pot) magnets are divied into pot neodymium magnet,pot alnico magnet,pot ferrite magnet.Their magnetic strength and prices will be relatively large differences.

These versatile U channel block/rectangular pot neodymium magnet with countersunk holes on their one side are compact and practical for integrating into your projects or ideas.These magnets hold very well against steel surfaces with direct touch and direct pull.To make it easy to be mounting,the u-channel holding magnets are made with one or two countersunk holes for screws according to the length.
