Overview
Key Features
HIGH-GRADE N50 NEODYMIUM DISC MAGNET: Each 5mm x 1mm disc delivers up to 0.6 lbs pull force — stronger than standard N35 in the same footprint, giving wargamers a firm, reliable hold without adding bulk
PRECISION FIT FOR 5MM DRILL HOLES: At exactly 1mm thick and 5mm across, these flat discs drop flush into a 5mm drill hole at 1mm depth — face sits level with surrounding plastic or resin, no visible gap
BUILT FOR MINIATURES AND CRAFT PROJECTS: Sized for Warhammer dreadnought arms and vehicle weapon swaps; also fits Gridfinity 5×1mm baseplates, scrapbook closures, resin pours, and needle minder builds
100-PACK, NICKEL-COPPER-NICKEL COATING: Triple-layer NiCuNi plating resists corrosion and bonds cleanly with cyanoacrylate and epoxy; 100 pieces cover multiple magnetizing projects or a craft run
STRONGEST PERMANENT MAGNET IN THIS FOOTPRINT: N50 grade in a 1mm-thin profile — maximum hold without routing deeper pockets or adding visible bulk; a step up from N35 packs sold at the same diameter

Pros & Cons
👍 Pros
- High N50 neodymium grade provides strong holding power despite the tiny 5x1mm size
- 100-pack quantity offers excellent value and plenty of magnets for large or multiple projects
- Triple-layer Nickel-Copper-Nickel coating resists corrosion and maintains a polished appearance
- Extremely compact size makes them ideal for miniature models, jewelry, crafts, and concealed fastening
👎 Cons
- Individual magnets are very small and easy to lose or accidentally swallow, posing a hazard around young children
- 0.6 lbs pull force per magnet is limited — multiple magnets may be needed for heavier items
- Thin 1mm profile makes them difficult to handle and separate individually from the stack
- Not suitable for high-temperature environments as neodymium magnets lose strength above approximately 80°C
Frequently Asked Questions
What is the pull force of each individual magnet?
Each 5x1mm magnet has a pull force of approximately 0.6 lbs (about 270 grams), which is notable given its tiny size.
What does the N50 grade rating mean for these magnets?
N50 refers to the neodymium grade, which indicates a very high magnetic energy product. N50 is among the stronger commercially available grades, meaning these small magnets punch well above their size in holding strength.
Are these magnets coated or treated to prevent corrosion?
Yes, each magnet features a triple-layer Nickel-Copper-Nickel coating that provides corrosion resistance and a smooth, polished finish for long-term durability.
What are the exact dimensions of each magnet?
Each disc magnet measures 5mm in diameter and 1mm in thickness, approximately 3/16 inch by 1/32 inch.
Are these magnets safe to use around electronics?
While small, neodymium magnets can affect magnetic storage media and certain sensitive electronics. They should be kept away from credit cards, pacemakers, and devices with magnetic sensors.
