Super Powerful N48 Block Magnet with Dual Countersunk Holes – 3" x 0.5" x 0.25" for Secure Mounting in Industrial, DIY, and Engineering Projects
Engineered for precision mounting and maximum holding power, this N48 neodymium magnet combines a slim bar profile with two precisely machined countersunk holes for secure attachment using #6 flat head screws. Ideal for mounting in jigs, fixtures, magnetic tool holders, and custom builds requiring high pull strength and reliable alignment. Rated for temperatures up to 80°C (176°F), it maintains magnetic stability under typical workshop and indoor industrial conditions.
Key Features:
- High-Strength Rare Earth Magnet: N48 grade, stronger than N45, N42, N40, N38, and N35 for superior magnetic performance.
- Dual Countersunk Holes: Two 0.292" x 0.165" 82° countersunk holes spaced 1.5" apart (center-to-center), compatible with #6 flat head screws for secure, flush mounting.
- BrMax: 13,800 Gauss for consistent, high magnetic performance.
- Pull Force: Approx. 35 lbs under ideal conditions (clean, flat, thick steel surface). Actual performance may vary based on surface material, texture, and mounting method.
- Triple Coating for Durability: Nickel-Copper-Nickel triple-layer coating ensures excellent corrosion resistance and extended lifespan in workshop or industrial environments.
- Magnetized Through Thickness: 0.25" (1/4") thick with poles on the two large faces for optimal surface contact.
Precision Design for Reliable Mounting
With 0.719" from the edge of the magnet to the center hole and 0.5625" from the edge to the start of the bevel, this magnet ensures precise placement in fixtures or equipment, providing secure, repeatable installation for engineering, fabrication, and DIY projects.Common Applications:
- Magnetic tool holders and shop fixtures
- Cabinet closures and secure latching systems
- Industrial jigs and alignment systems
- Magnetic tool bars and utility holders
- DIY projects requiring flush, secure magnet mounting
- Robotics and engineering assemblies needing reliable positioning

Frequently Asked Questions (FAQ)
Can I use this magnet outdoors?
It can be used in controlled outdoor settings, but pairing with a weather-resistant enclosure or sealing for extended exposure is recommended.
How should I mount this countersunk magnet?
Use #6 flat head screws in the countersunk holes for a flush, secure installation on metal, wood, or plastic surfaces.
Is N48 grade suitable for industrial applications?
Yes. N48 grade offers higher magnetic strength, making it ideal for heavy-duty holding, alignment, and tool fixture applications.
What precautions should I take during handling?
These magnets are very powerful and can snap together quickly. Handle with caution, keeping them away from electronics and sensitive devices.
What is the maximum temperature this magnet can withstand? This N48 magnet performs optimally up to 80°C (176°F). Beyond this, magnetic strength may degrade permanently.
Will the pull force always be 35 lbs?
The 35 lb pull rating is based on ideal lab conditions using thick, flat steel. In practical use, pull force may vary depending on mounting surface smoothness, thickness, and material type.
Secure, Powerful, and Precision-Ready
From industrial tool holding to DIY shop builds, this N48 block magnet with dual countersunk holes delivers unmatched strength, stability, and ease of installation, making it an essential component for applications requiring a secure magnetic solution.
