Product Overview
Neodymium magnets are the world's strongest commercially available permanent magnets. Super Magnet Store offers premium-quality N52 neodymium rare earth magnets manufactured to stringent quality standards using advanced production technology. These magnets provide exceptional holding power, dependable performance, and long-term durability for industrial, commercial, and engineering applications.
This N52 neodymium block magnet measures 2" x 1" x 1/2" and features two dual-sided countersunk mounting holes for secure installation. Each countersunk hole measures 0.355" x 0.195" with an 82-degree taper and is designed for use with #8 flat head screws. The holes are spaced 1 inch center-to-center, allowing for secure and stable mounting in demanding applications.
Manufactured from neodymium, iron, boron, and other rare earth materials, this magnet generates over 89 lbs of pull force under ideal conditions. The powerful N52 grade provides maximum magnetic performance while the Nickel-Copper-Nickel triple-layer coating offers superior protection against corrosion and wear.
What Is a Countersunk Neodymium Magnet?
A countersunk neodymium magnet is a rare earth permanent magnet designed with recessed mounting holes that allow flat head screws to sit flush with the magnet surface. This design enables secure mechanical attachment while maintaining maximum magnetic holding strength.
How Strong Is This Magnet?
This N52 neodymium countersunk block magnet generates over 89 lbs of pull force under ideal conditions. Actual holding strength depends on steel thickness, surface finish, air gaps, mounting configuration, and environmental conditions. With a Br Max rating of 14,500 Gauss, it delivers exceptional magnetic performance for industrial and commercial applications.

Common Questions About This Magnet
How much weight can this magnet hold?
This magnet provides over 89 lbs of pull force under ideal conditions. Actual holding capacity depends on surface material, installation method, and application design.
What screws fit the countersunk holes?
The 0.355" x 0.195" dual-sided countersunk holes are designed for #8 flat head screws.
What is the hole spacing?
The distance between hole centers is 1 inch.
Is N52 stronger than N50?
Yes. N52 is the strongest commercially available neodymium magnet grade and provides greater magnetic energy and holding force than N50 magnets.
Can this magnet be used outdoors?
The Nickel-Copper-Nickel coating provides excellent corrosion resistance, but additional protection is recommended for long-term outdoor exposure.
What direction is it magnetized?
This magnet is magnetized through the 1/2-inch thickness, with the north and south poles located on the 2" x 1" faces.
