Quick Answers

Question Answer
How strong is this magnet? Over 46 lbs of pull force under ideal conditions.
Is N42 stronger than N35? Yes. N42 is stronger than N40, N38, and N35 grades.
What is this magnet made of? NdFeB (Neodymium-Iron-Boron) rare earth material.
Can this magnet rust? The Nickel-Copper-Nickel coating provides excellent corrosion resistance, but prolonged exposure to moisture or coating damage may eventually lead to corrosion.
What is it commonly used for? Cabinet doors, industrial fixtures, machinery mounting, woodworking projects, magnetic latches, and heavy-duty mounting applications.

Product Overview

Neodymium magnets are the world's strongest commercially available permanent magnets. Super Magnet Store offers premium-quality N42 neodymium 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 1/4" and features two dual-sided countersunk mounting holes for secure installation. Each countersunk hole measures 0.36" x 0.18" with a 90-degree taper and is designed to work with #6 and #8 flat head screws. The holes are spaced 1 inch center-to-center, providing secure mounting and excellent load distribution.

The Nickel-Copper-Nickel triple-layer coating offers superior corrosion resistance and durability, while the magnet's powerful holding force of over 46 lbs makes it ideal for demanding mounting and fastening applications.

What Is a Neodymium Block Magnet?

A neodymium block magnet is a rectangular rare earth permanent magnet made from neodymium, iron, and boron (NdFeB). Block magnets provide exceptional holding force and a large contact surface area, making them ideal for industrial equipment, manufacturing fixtures, engineering projects, cabinetry, automation systems, and custom magnetic assemblies.

How Strong Is This Magnet?

This N42 neodymium countersunk block magnet generates over 46 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 13,200 Gauss, it delivers powerful magnetic performance while allowing secure screw mounting.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet provides over 46 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 0.36" x 0.18" dual-sided countersunk holes are designed to accommodate both #6 and #8 flat head screws.

What is the hole spacing?

The two mounting holes are spaced 1 inch center-to-center.

Is N42 stronger than N35?

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

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating provides corrosion resistance, but additional protection is recommended for prolonged outdoor exposure.

What direction is it magnetized?

This magnet is magnetized through the 1/4-inch thickness, with the north and south poles located on the 2" x 1" faces.
