Material Description:

Our 32mm x 6mm countersunk N52 ring magnets provide an exceptionally strong, mechanically anchored fastening solution for the most demanding commercial and engineering environments. The substantial 6mm thickness creates a deep, intense magnetic field capable of penetrating through finishes or small air gaps. Featuring an integrated 5mm countersunk hole, it accommodates heavier-duty M5 or flathead screws. Because the flathead screw drops perfectly flush within the recessed pocket, it permits uninterrupted metal-to-magnet surface contact, maximizing the available 52.5 lbs of holding force.

Handling Advice: EXTREME DANGER: Industrial-scale countersunk magnets require careful, controlled installation. With over 50 lbs of pull force, two magnets will attract with severe velocity from several inches away. Impact can lead to crushed or broken bones and will cause the brittle magnets to shatter into sharp fragments. Over-tightening screws with power tools can also cause the magnet to split at its center—always hand-tighten with care and use specialized tools.

Warnings and Safety Information:

• Severe Crush Hazard: Can cause permanent injury to hands and fingers. For professional use only.
• Fragility Hazard: Do not over-tighten screws. Extreme impact force from snapping together WILL shatter the ring wall.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants at all times.
• Electronics: Keep well away from hard drives, credit cards, and all sensitive electronic equipment.

Applications:

• Heavy-duty hidden closures for heavy security doors, hidden rooms, and custom cabinetry
• Mechanical anchoring for large removable wall partitions, acoustic panels, and massive structural graphics
• High-vibration shop-tool organization, heavy equipment mounting, and custom workbench hold-downs
• Secure, screw-in fasteners for industrial modular retail displays, heavy signage, and exhibition frames
• Heavy-duty 3D-printed equipment enclosures and removable machine guarding plates
