Product Description

Very Strong N52 Neodymium Magnets 1 in x 1/4 in w/Dual Sided Countersunk Hole Disc

Very Strong N52 1 in x 1/4 in w/Dual Sided Neodymium Magnets Countersunk Hole Disc

Very Strong N52 Neodymium Magnets 1 in x 1/4 in with Dual Sided Countersunk Hole Disc – Premium Rare Earth Magnet for Secure Mounting

Introducing the premium N52, engineered for maximum strength and secure mounting in demanding applications. This 1-inch x 1/4-inch thick disc magnet with a dual-sided countersunk hole combines exceptional holding force with installation versatility, making it ideal for mechanical assemblies, fixtures, and precision mounting where a low-profile yet powerful magnet is needed.

Key Features:

• Compact High-Strength Disc Magnet: 1-inch diameter x 1/4-inch thickness provides a low-profile yet stable mounting surface.
• Dual-Sided Countersunk Hole: 0.355" x 0.195" (82-degree) countersunk hole tapered on both sides, compatible with #8 or #10 flat head screws for flush, secure installation.
• Ultra-Strong N52 Grade: Stronger than N50, N48, and N45 grades, with a BrMax of 14,800 gauss for maximum magnetic force in a compact footprint.
• Estimated Pull Force: Holds over 30 lbs under ideal lab conditions (clean, flat steel with full contact). Actual performance may be lower if installed on painted, uneven, or non-ferrous surfaces, or if improper screws are used.
• Max Operating Temperature: Rated for use up to 80°C (176°F). Exposure to higher temperatures may cause permanent loss of magnetic strength.
• Triple Coated: Nickel-Copper-Nickel plating for excellent corrosion resistance and durability.
• Magnetized Through Thickness: North and south poles on the flat faces for optimal alignment and stability in your projects.

Technical Specifications

Frequently Asked Questions

What is the advantage of the dual-sided countersunk hole?
The dual-sided countersunk hole allows for flush mounting with flat head screws from either side of the magnet, offering installation flexibility while maintaining a clean appearance and secure hold in your projects.

How strong is this magnet compared to others?
This N52 grade magnet is the strongest commercially available neodymium magnet grade, offering higher holding power than N48, N45, and lower grades, making it suitable for high-force and precision applications.

What screws are compatible with this magnet?
The countersunk hole is designed for #8 or #10 flat head screws, allowing secure and flush mounting in wood, metal, or composite surfaces.

Will this magnet always hold 30+ lbs in real-world use? No. The 30+ lb rating is based on lab tests with flat, bare steel. Actual holding force may be lower if the surface is curved, coated, dirty, or the screw doesn’t allow flush contact. For best results, ensure full contact with clean ferromagnetic surfaces and use compatible flat head screws.

Are there safety precautions I should follow when using this magnet?
Yes. Due to its extreme strength, this magnet can snap onto metal or other magnets quickly, risking pinched fingers or chipping. Always handle with care, keep away from electronics and pacemakers, and avoid colliding the magnet with hard surfaces.
