Cap Neodymium Disc Magnets: Strength, Durability, and Mounting Made Simple
Cap neodymium disc magnets are industrial magnets engineered for precision, power, and practicality. At Magfine.ca, we supply these magnets throughout Canada for use in fixtures, signage, production lines, DIY projects, and heavy-duty mounting. Each magnet is housed in a steel casing that maximizes strength and protects against damage—making them more reliable than standard disc magnets in demanding environments.
Whether you're mounting tools in a garage or outfitting an assembly line, these magnets offer unbeatable holding force with a professional finish. Our cap neodymium magnet collection features various sizes, pull strengths, and mounting styles—all shipped quickly across Canada.
What Are Cap Neodymium Disc Magnets?
Unlike bare neodymium magnets, cap disc magnets are enclosed in a steel cup that focuses the magnetic field through one face. This design improves their effective pull strength while shielding the magnet from cracks, chips, and corrosion. Many also feature a center hole or countersunk design, allowing easy screw or bolt installation on a wide range of surfaces.
The result? A rugged, concentrated, and reusable magnetic solution that meets industrial standards—ideal for Canadian manufacturers, retailers, and tradespeople.
Why Choose Cap Magnets Over Regular Disc Magnets?
- Stronger Holding Power: The steel casing channels magnetic force through one face, increasing usable strength.
- Greater Durability: Protected against cracking, corrosion, and repeated impact.
- Easier Mounting: Pre-built holes or countersinks make secure installation effortless.
- Safe for Frequent Use: Steel shells reduce direct magnet-to-metal contact and risk of breakage.
Common Uses of Cap Neodymium Disc Magnets
1. Industrial Workstations & Manufacturing
Secure tools, jigs, panels, or materials to steel surfaces. In environments where precision and strength are critical, cap magnets outperform standard industrial magnets.
2. Magnetic Fixtures & Signage
Design clean, hidden installations in retail environments using cap magnets. They offer a flush mount with strong adhesion—perfect for displays and backlit panels.
3. Tool Organization & Garage Use
Mount hooks, holders, bins, and lights with high-strength magnets in shops, garages, or workstations. Their corrosion-resistant coatings ensure long-term performance indoors and out.
4. DIY, Prototyping, and Tinkering
For inventors and engineers across Canada, these magnets are ideal for modular builds or fixtures that require strong, repeatable magnetic force.
5. Automation & Robotics
Cap magnets hold components, activate switches, or assist with magnetic positioning without mechanical fasteners.
Available Styles, Sizes, and Coatings
Magfine’s cap magnets come in various diameters and heights, from small 16 mm models to large 75 mm magnets capable of handling over 100 pounds of force. Options include:
- Countersunk Cap Magnets: Designed for flush mounting using flat-head screws.
- Threaded Hole Designs: Perfect for interchangeable attachments or hooks.
- Rubber-Coated Cap Magnets: Add friction and protect delicate mounting surfaces.
All magnets are made from high-grade neodymium (N35 to N52) and housed in precision-engineered steel cups, often finished with a nickel or zinc coating for enhanced corrosion resistance.

Frequently Asked Questions
What makes cap magnets stronger than regular disc magnets?
The steel cup housing redirects the magnetic field to one face, intensifying the holding force by up to 2–4x compared to a standard disc magnet.
Can these magnets be used outdoors?
Yes. Many of our cap magnets are coated with nickel or zinc for corrosion resistance and can be used in sheltered outdoor applications.
Do cap magnets leave marks or scratches?
Standard cap magnets can scratch metal surfaces if dragged. Rubber-coated versions or soft mounting pads are ideal for delicate finishes.
How do I know which size or style to choose?
Refer to the pull force and mounting method listed on each product page, or contact us for advice.
Is Magfine based in Canada?
Yes. While Magfine Corporation is headquartered in Japan, Magfine.ca operates locally to serve customers throughout Canada with fast delivery and bilingual support.
