Product Description
These high-powered 50mm x 12mm x 4mm x (4mm x 4mm Double Hole) Black Epoxy Neodymium magnets have two countersunk holes that allow them to be drilled or fit into place. They are incredibly strong and commonly used in DIY, crafts, furniture design, fixings, kitchen design, lock mechanisms and science experiments. These neodymium magnets have an epoxy coating which is one of the most durable forms of coating available. Black Epoxy magnets do not corrode like traditional Ni-Cu-Ni coated magnets and are perfect for wet humid and salty environments. These magnets are designed with two holes that allow them to be easily fixed and drilled into surfaces that aren’t magnetic.Â
Quality Assurance
Introducing our premium N52-grade 50mm x 12mm x 4mm x (4mm x 4mm Double Hole) Block Black Epoxy Neodymium Countersunk magnets, meticulously crafted to meet your diverse needs with unparalleled performance. These magnets boast a triple-layer coating of nickel-copper-nickel (Ni-Cu-Ni), ensuring maximum protection against corrosion, enhancing longevity, and maintaining a pristine appearance.
Our neodymium block countersunk magnets are manufactured to comply with REACH and RoHS standards, meaning they are free from harmful substances and environmentally safe. The Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) regulation governs the production and usage of chemicals, while the Restriction of Hazardous Substances (RoHS) directive restricts the use of specific hazardous materials in electrical and electronic equipment. By adhering to these standards, we guarantee the safety and quality of our products.
The N52 grade indicates that our neodymium magnets possess one of the highest energy products available on the market. This translates to exceptional magnetic strength, allowing them to be utilised effectively in various applications, from motor components and magnetic couplings to mounting and holding fixtures.
We pride ourselves on delivering top-quality products to our customers. We have implemented an extensive quality check programme to ensure that our neodymium magnets pass the highest quality standards. Each magnet undergoes rigorous tests and inspections, providing reliable, powerful magnets that stand the test of time.
Neodymium is a naturally fragile metal that lacks the elasticity commonly found in other metals. Due to their inherent brittleness, handling neodymium magnets with care is crucial. Clashing two neodymium magnets together may cause them to crack or sustain damage. Always exercise caution when using and storing these powerful magnets to ensure optimal performance and longevity. Trust in our premium magnets' quality, performance, and reliability, expertly crafted to meet the most stringent UK and international standards.

Gold Standard Quality Control
To ensure that our magnets meet the highest standards, we employ extensive testing procedures at every stage of production:
- Sourcing and Preparation: We source high-grade materials from trusted partners and carefully prepare them to optimise magnetic properties.
- Manufacturing: Advanced processes including precise pressing, controlled sintering, and exact machining ensure uniformity and structural integrity.
- Finishing and Testing: Protective coatings are applied and inspected, magnets are magnetised to achieve consistent strength, and each product undergoes thorough final checks for size, strength, and quality before shipment.
Commitment to Compliance
Magnet Store is fully committed to adhering to global safety and environmental standards. Our products comply with key international regulations, providing assurance that they are both safe to use and environmentally responsible.
- RoHS Compliance: Our magnets meet the Restriction of Hazardous Substances (RoHS) directive, ensuring they are free from harmful materials such as lead, mercury, and cadmium. This compliance protects the environment and ensures the safety of all who handle our products.

Returns Policy
Your satisfaction is our priority at Magnet Store. That’s why we offer a 30-day return policy to give you peace of mind with every purchase. If for any reason you are not completely satisfied with your magnets, you may return them within 30 days for a full refund of the purchase price, excluding shipping costs.
To ensure the safe return of your product and to facilitate a smooth refund process, we require that the package be sent via tracked delivery. This measure helps us confirm the safe arrival of your return. Please note that we cannot process a refund if the package does not reach our facility.
When returning the magnets, please ensure they are in resellable condition, just as you received them. Proper padding is crucial when packaging your return; inadequate padding could cause the magnets to become attached to machinery during transit, which may prevent the package from arriving safely. Refunds can only be issued upon successful delivery and after we have verified that the magnets are returned in their original condition.

Custom Magnets
At Magnet Store, we tailor state-of-the-art magnetism to your needs. Whether you need high-performance neodymium magnets for complex industrial applications or require the distinctive qualities of Samarium Cobalt (SmCo), Ferrite, or Alnico, our expertise ensures the ideal solution for every requirement. With our advanced engineering, precision manufacturing, and flexible approach, we deliver exactly what you need—quickly and cost-effectively. With one of the industry’s fastest lead times and no minimum order quantities, we are an excellent choice for both small and large-scale projects and we’re here to support your needs. For more information, click here.
- Affordability & Wholesale Pricing: In many cases, custom magnets are more cost-effective than standard website prices, particularly for larger orders. This is because we cut overheads like stock management, warehousing, and operational costs, allowing us to pass the savings directly to you. Custom manufacturing starts at £99, with prices per unit decreasing as order quantities increase. For smaller magnets (1mm to 30mm), ordering 500 pieces or more typically secures better pricing. For larger magnets (over 30mm), around 100 pieces are often enough for cost-effective rates. Bulk orders of 1,000+ units unlock even more competitive wholesale pricing, well below standard retail rates.
- Custom Shapes with High Precision: We produce magnets in virtually any shape with precision down to 0.05mm. For complex designs, simply provide CAD files or detailed drawings, and we’ll produce your magnets to exact specifications. Please note, in rare instances, ferrite magnets may require a molding fee, however, this will be clearly displayed on your quote.
- Advanced Neodymium Grades: We provide high-performance neodymium grades rarely available on the market, including N54, N55, N56, and N58, offering exceptional power for demanding applications. Our capability to produce these advanced grades sets us apart, meeting the needs of specialised and high-demand projects. Minimum order quantities (MOQ) may apply for grades N55 and above due to their specialised manufacturing processes.
- Flexible Ordering Options: We offer flexible ordering with no strict minimum order quantity (MOQ) for most custom magnets, which means you can easily order samples and low quantities—no questions asked. Please note, advanced grades (e.g. N55 and above) and special coatings may require an MOQ.
- Fast Production & Lead Times: We deliver quickly, with most orders completed in just 12-15 business days—significantly faster than the industry average of 25-30 days. Please note, advanced grades (N55 and above), specialised coatings or materials may have slightly longer lead times.
