N35 Neodymium Magnets with Countersunk Holes - Super Strong Rare Earth Magnets

Experience the incredible holding power of genuine N35 grade neodymium rare earth magnets with convenient countersunk screw holes. These super-strong permanent magnets are perfect for DIY projects, industrial applications, crafts, and countless creative uses.

Why Neodymium Magnets?

• Strongest Permanent Magnets: Neodymium (NdFeB) magnets are the most powerful commercially available magnets
• N35 Grade: Professional-grade magnetic strength suitable for most applications
• Countersunk Holes: Pre-drilled holes allow easy mounting with screws for permanent installation
• Rare Earth Composition: Made from neodymium, iron, and boron for maximum magnetic force
• Permanent Magnetism: Will not lose magnetic strength over time under normal conditions

Versatile Applications

• DIY Projects: Cabinet closures, magnetic latches, tool holders, knife racks
• Industrial Use: Sensors, motors, magnetic separators, holding fixtures
• Home Organization: Refrigerator magnets, whiteboard holders, garage organization
• Crafts & Hobbies: Jewelry making, model building, magnetic closures
• Electronics: Speakers, headphones, hard drives, magnetic switches
• Workshops: Tool organization, parts holding, jig fixtures
• Retail Displays: Signage mounting, product displays, POP fixtures

Safety & Handling

⚠️ Important Safety Information:

• Keep away from children - small magnets can be dangerous if swallowed
• Handle with care - strong magnets can pinch fingers when they snap together
• Keep away from pacemakers, credit cards, and electronic devices
• Store magnets separated to prevent damage
• Do not heat above 80°C as this will demagnetize them

Package Contents

Each order includes your selected quantity of N35 neodymium magnets with countersunk holes, carefully packaged to prevent damage during shipping. Magnets are separated to prevent accidental snapping together.

Pro Tip: When installing, use non-magnetic screws (brass or stainless steel) to avoid interference with the magnetic field. The countersunk hole is designed for standard flat-head screws.
