Overview

Versatile and Powerful Magnets for Endless Applications

These Disc Magnets are perfect for a wide range of DIY, crafting, and industrial applications. Made from strong N48 material, these magnets provide a secure and reliable hold.

  • Brand: BOOM
  • Type: Disc Magnets (Cylinder)
  • Dimensions: 1/2" x 1/4" (12x6mm)
  • Material: N48
  • Quantity: 10 Pack

Key Features

STRONG N48 PERFORMANCE – N48-grade rare earth magnets hold up to 11.7 lbs each — noticeably stronger than standard N35/N42 disc magnets of the same size; verified grade for projects where holding power matters

PRECISE DIMENSIONS – Each disc measures exactly 1/2 inch diameter × 1/4 inch thick (12.5 x 6 mm); consistent sizing makes them reliable for closures, fixtures, jigs, and any application requiring repeatable fit

BROAD APPLICATION RANGE – Magnetic cabinet latches, tool holders, whiteboard and fridge mounting, woodworking jigs, craft closures, cosplay assembly, escape room mechanisms, and sensor or robotics projects

PACK OF 10, TRIPLE-LAYER COATED – Each magnet has a nickel-copper-nickel finish for corrosion resistance and a smooth surface that won't scratch steel; 10 pieces per pack with consistent dimensions and magnetization

N48 GRADE ADVANTAGE – N48 delivers measurably higher flux density than the commodity N35 standard, making it the preferred choice for applications where a smaller magnet footprint must carry real load

Pros & Cons

👍 Pros

  • Features a strong N48-grade rare earth magnet composition, providing significantly higher holding power compared to standard grades.
  • Each disc magnet is verified to hold up to 11.7 lbs, making them suitable for demanding applications where strong adhesion is crucial.
  • Boasts precise dimensions of 1/2 inch diameter by 1/4 inch thick, ensuring consistent sizing for reliable fit in various projects.
  • Equipped with a triple-layer nickel-copper-nickel coating, enhancing corrosion resistance and providing a smooth, non-scratch surface.
  • Comes in a convenient pack of 10, offering multiple magnets for diverse applications from closures to robotics.

👎 Cons

  • As N48-grade magnets, they are powerful, which might require careful handling to avoid accidental pinching or damage to sensitive electronics.
  • The specific temperature limits for maintaining magnetic strength are not provided, which could be a factor in high-heat applications.
  • While strong, these are disc magnets, and their holding force may be reduced if not in full contact with a ferromagnetic surface.
  • The description does not specify if these magnets are rated for outdoor use, despite their corrosion-resistant coating.
  • The pack size is fixed at 10, which might not align with the needs of users requiring a different quantity.
