Counterbore Neodymium Magnets, High Strength Round NdFeB Magnets with Sink Hole for Screw Mounting
Standard Sink Hole Sizes In Stock, Custom Grade & Dimension Industrial Counterbore Magnets
Counterbore neodymium magnets are one of the most practical structural rare earth magnets for industrial installation and mechanical fixing. Different from ordinary flat disc magnets that rely on glue or external brackets, these round magnets come with precision pre-drilled counterbore sink holes, allowing flat-head screws to be fully embedded and locked flush with the magnet surface. This unique design achieves ultra-flat, stable and non-shaking fixed installation, solving the looseness, displacement and unstable adsorption problems of traditional magnet mounting methods.
Made of high-density sintered NdFeB rare earth material, our counterbore magnets provide extremely strong vertical suction force. The round steel shell structure concentrates magnetic flux on the working surface, greatly improving holding efficiency while avoiding magnetic leakage. Even under long-term mechanical vibration, equipment operation and frequent disassembly, the magnet maintains stable magnetism without demagnetization or falling off.
Each counterbore magnet is fully nickel plated for comprehensive anti-rust, anti-oxidation and wear resistance. The smooth chamfered edge protects equipment surfaces from scratches, while the precisely positioned sink hole ensures accurate screw alignment and flush installation. For high-temperature machinery environments, SH and EH high-temperature resistant grades are available to guarantee continuous stable performance under high heat working conditions. For humid and outdoor equipment, epoxy coating can be customized for enhanced waterproof and salt-spray resistance.
All mainstream outer diameters and sink hole sizes are in stock for fast shipping. We also support OEM customization including custom outer size, hole aperture, thickness, magnet grade and surface treatment according to mechanical drawings.
Widely applied in industrial fixture positioning, workshop tool holders, automation equipment mounting, CNC machine auxiliary fixing, advertising bracket installation, mechanical testing instruments and mold auxiliary positioning. Suitable for small sample testing and large batch factory wholesale, with strict dimensional and magnetic inspection before delivery.
