Guy's Budget Range 4 mm x 1 mm N38 grade disk - PACK OF 50

Technical Specifications These are from our BUDGET RANGE of magnets, ideal for the budget conscious when the tolerances are less important than normal.  Instead of our usual +/-0.1mm tolerances, they have +/-5% tolerances on any dimension. Diameter: 4 mm (0.16") Thickness: 1 mm (0.04") A mm x ially Magnetised through the thickness so that one flat face is north, the other is south Weight: 0.09g Grade: N38 Coating: Ni-Cu-Ni (Nickel-Copper-Nickel) Ma mm x imum Temp: 80°C / 176°F Theoretical Ma mm x imum Pull: 0.51lb / 8.1oz / 229g Calculated Ma mm x Vertical Hold-guidance only: 0.10lb / 1.6oz / 45g WARNINGS: All neodymium magnets are unsuitable for children; do not ingest. All neodymium magnets are brittle; do not allow these magnets to jump together or to an iron/steel surface - they will break, crack, chip or shatter. Thin neodymium magnets DO NOT FLEX , if you attempt to flex them they will snap in half.
