Product Overview

Neodymium magnets are the world's strongest commercially available permanent magnets. Super Magnet Store offers premium-quality N42 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 N42 neodymium block magnet measures 2" x 1" x 1/2" and features two dual-sided countersunk mounting holes for secure installation. Each hole is tapered 82 degrees on both sides and measures 0.355" x 0.195", making it compatible with #8 flat head screws. The holes are spaced 1 inch center-to-center for secure mounting and excellent load distribution.

Manufactured from neodymium, iron, boron, and other rare earth materials, this magnet delivers over 72 lbs of pull force under ideal conditions. The Nickel-Copper-Nickel triple-layer coating provides superior corrosion resistance and durability for demanding environments.

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 permanent, secure installation while maintaining maximum magnetic holding power.

How Strong Is This Magnet?

This N42 neodymium countersunk block magnet generates over 72 lbs of pull force under ideal conditions. Actual holding strength depends on surface material, thickness, air gaps, temperature, and mounting configuration. With a Br Max rating of 13,200 Gauss, it provides powerful holding force for industrial and commercial applications.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet provides over 72 lbs of pull force under ideal conditions. Actual holding capacity depends on the mounting surface, installation method, and application design.

What screws fit the countersunk holes?

The 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 N42 stronger than N35?

Yes. N42 magnets provide significantly greater magnetic strength and holding force than N35 magnets of the same dimensions.

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.
