Boost Your Projects with Powerful N42 Neodymium Disc Magnets
This premium neodymium disc magnet is made from N42-grade NdFeB (neodymium-iron-boron) rare earth alloy, produced under ISO 9001 quality standards for exceptional reliability. With a 1" diameter and 1/4" thickness, it features a #10 countersunk hole for seamless mounting using flat-head screws. Axially magnetized with poles on the flat surfaces, it delivers optimal performance for secure holding.
Key Features:
- Strength and Performance: N42 grade offering 23 lbs pull force and 13,200 Gauss surface field (1.32 Tesla) for robust applications.
- Mounting Ease: #10 countersunk hole designed for flat-head screws, enabling flush installation.
- Durability: Triple-layer NiCuNi (nickel-copper-nickel) plating provides excellent corrosion resistance and longevity.
- Precision Build: Tolerances of +/-0.002" (including coating) ensure accurate fit and function.
Ideal Applications:
Perfect for metal fabricators, DIY enthusiasts, handymen, crafters, and even medical uses like arthritis or back pain relief. Use in industrial holding, magnetic closures, tool organization, and creative projects requiring strong neodymium disc magnets with countersunk holes.
Important Safety Notes:
- Neodymium magnets are brittle and may chip or shatter—handle carefully to prevent injury.
- Keep away from pacemakers, children under 10 (supervision required for older kids), and sensitive electronics.
- Backed by a 10-year warranty on magnetic strength under normal conditions (void in elevated temperatures, vibration, opposing fields, outdoors, or humid/salty environments without protection).

Warranty
This magnet includes a 10-year warranty for its magnetic strength, provided it is used under normal conditions. Usage in environments with elevated temperatures, significant vibration, or intense opposing magnetic fields will render this warranty null and void. It is also not suitable for use outdoors or in areas with high humidity or salt content, unless additional protective insulation measures are implemented.Product Videos

N42 1"x1/4" countersunk
These very strong magnets are paired with another of the opposite polarity. Six pairs of these magnets are sandwiched on a 4"X6" piece of 0.25 inch thick rubber sheet and covered with a soft cloth to make a medical pad. A nylon nut and bolt hold each magnet pair to the mat. The mat is used for treatment of arthritis and back pain.
