Neodymium Disc Magnets – 8mm x 3mm, 50-Pack
Neodymium Disc Magnets – 8mm x 3mm Compact high-strength magnets for 3D printing, crafts, fixtures, jigs, tool holders, and maker projects. This 50-pack of 8mm x 3mm neodymium disc magnets provides strong holding force in a small footprint. The extra 4mm thickness makes them a good choice for projects that need more magnetic strength than thinner 6mm disc magnets can provide. Product Details Quantity: 50 magnets Diameter: 8mm Thickness: 3mm Magnet grade: neodymium Shape: round disc Smooth plated surface Common Uses 3D-printed enclosures, lids, and snap-together assemblies ATC tool-cup bases and magnetic CNC accessories Tool holders and shop organization CNC and maker-space jigs or fixtures Craft projects, signs, and display pieces Prototypes, classroom projects, and small mechanical assemblies Installation Tips Confirm magnet polarity before gluing magnets into mating parts. Use an adhesive suitable for both the magnet plating and the project material. Press magnets into properly sized recesses without excessive force. Keep magnets clean and dry for best long-term performance. Allow adhesive to cure fully before placing the magnets under load. Safety Not a toy. Keep away from children, pets, pacemakers, magnetic storage media, and sensitive electronics. Small magnets can be dangerous if swallowed. Neodymium magnets are brittle and may chip or break if allowed to snap together.
