These 3/8" x 1/4" N52 neodymium disc magnets are built for maximum strength in a compact, thick profile. The 3/8" diameter provides excellent surface contact for a secure grip, while the substantial 1/4" thickness delivers deep magnetic pull and superior stability—making them significantly stronger than thinner discs of the same diameter.

Crafted from high-grade N52 rare earth neodymium, these magnets offer top-tier performance for demanding applications. Whether you’re securing closures, embedding magnets into materials, or organizing heavier items, they provide a firm, consistent hold you can rely on. Each magnet is finished with a smooth nickel coating for durability and a clean, polished look.

Common Applications:

  • Holding heavier items on metal surfaces
  • Magnetic closures for cabinets, boxes, and enclosures
  • Embedding into wood, plastic, or resin for hidden mounts
  • Workshop fixtures, tool holders, and organization
  • DIY crafts, models, and custom builds
  • Garage, industrial, or hobby use

    Powerful N52 Magnets

    One of the standout features of these N52 magnets is their impressive strength. They are among the strongest commercially available magnets, and their powerful pull force is evident as soon as you start using them. Whether I’m working on DIY projects, scientific experiments, or even just organizing my workspace, these magnets provide reliable and consistent performance. They hold firmly in place, ensuring that whatever they’re attached to stays secure.The quality of these magnets is also noteworthy. Each magnet feels solid and well-constructed, with a smooth finish that adds to their durability. They are less prone to chipping or breaking compared to other, lower-quality magnets, which is a significant advantage, especially for projects that require repeated use or strong force. The consistency in quality across the entire set is commendable, making them a dependable choice for any application.Another major benefit is their versatility. These magnets are perfect for a wide range of uses, from hobbyist projects to professional applications. I’ve used them in everything from creating magnetic closures for DIY crafts to holding tools and other items in my workshop. Their small size yet powerful strength makes them incredibly useful for intricate tasks where precision and reliability are key.Additionally, the set I purchased comes with a generous number of magnets, providing great value for the price. It’s reassuring to know that I have plenty of magnets on hand for various tasks without having to constantly reorder.I couldn’t be happier with these N52 magnets. Their combination of strength, quality, and versatility makes them an indispensable tool for any project. I highly recommend them to anyone in need of powerful and reliable magnets.

    True to size and strong

    Holidays are coming up and I am going to make some fridge magnets. I wanted something robust that won't slide off the fridge door when you close it and these are perfect for the task.The magnets are true to size and their pull is really strong. The case they came in works well to protect them from attracting things dirt and debris.Bottom line: If you're looking for strong magnets these are as good as any for projects if they're the right size for you.

    Strong magnets for project

    These magnets really grab. I made dust collector coupler. These couplers hang vertically so I needed something stronger than regular magnets.

    MIGHTY!

    The description says powerful, but I was skeptical. BEWARE! These magnets are ~incredibly~ strong and take a bit of finesse in order to remove when in contact with each other. For me, its exactly what I needed!

    So Helpful in the Classroom!

    Almost all of my high school classroom walls are covered with whiteboard and we are strongly discouraged from hanging things elsewhere. These little magnets do the job of holding up informational posters and small realia to support my instruction! They are very small so practically disappear into the work! I really appreciate the teensy "extra hands!"

    Very strong

    These magnets are exactly as described on the product page and they are very strong. Rubber padding was added between each magnet so they are a little bit easier to separate. Make sure to handle them with care, as the magnet force is so strong and the material is brittle.

    Super powerful

    These magnets are VERY strong. They come in a nice plastic storage case and have a round spacer between each to help separate them. They can be a bit tough to separate due to being so powerful, they just want to stick together.Strong enough to hold fairly heavy objects to metal surfaces. Great for holding stacks of paper to the fridge, or crafts where you need the extra magnetic pull.Very good quality overall.

    Good strong magnets

    These are strong magnets and the size is accurate to the listing. They work great.

    REALLY strong

    I'm thoroughly impressed with these exceptionally strong magnets! They possess an intense magnetic force that's both remarkable and cautionary - as I discovered when trying to separate them with my bare fingers (ouch!).To mitigate this, the magnets come thoughtfully separated by a small plastic insert, making it easier to pull them apart. However, if you accidentally allow them to snap together without the separator, be prepared for a challenge - they're that strong!If you require a reliable and robust magnet that can handle heavy-duty tasks, look no further! I wholeheartedly recommend these magnets for their unparalleled strength and effectiveness. Just be sure to handle them with care (and maybe some protective gloves)!
