    Default Nail Count Chart?

    Can anyone please point me to a nail count chart?

    Trying to work out how many 50mm x 2.8mm bright bullethead nails per kg so I decide if I need 5kg or 15kg!

    Thanks, WW

    Default Nail weight chart

    Unfortunately that would mean I'd have to buy 500 to weigh to work out how many to buy! And all packages are weight so I don't know how much 500 weighs to buy them

    Volume of a cylinder = πr^2L
    Volume of nail = 3.14159 x 0.0014 x 0.0014 x 0.05 = 0.00000030787582m^3
    Density of steel = 7850 kg/m^3
    Number of nails per kg = (1 / 0.00000030787582) / 7850 = 414 nails per kilogram

    Nice, John.

    Euclidean geometry might be funny, but it's also very handy. You could get a much closer estimation if you measured a sample nail. If it is exactly 50mm long from the top of the jolt head to the tip of the chisel point, and if it were exactly 2.8mm diameter, then there'd be very close to 414 nails/kg.

    Of course a nail isn't a perfect cylinder, and you could calculate the amount of extra steel around the jolt head, and deduct the missing steel around the chisel point, but they'd come pretty close to cancelling each other out.

    ...or... fill a container with water. Poke a very small hole just below the waterline and let the water drain down to the hole. Now drop in, say 10 nails. Measure the amount of water that drains out of the hole in ML.

    Now multiply the number of ML by the steel-water density. (I.e. 7.85 seeing as water has a density of 1000 kg per m^3). Divide the result by the number of screws you dropped in the water and you have an estimate of how much one nail weighs.

    @ 4 degrees celsius (temperature affects water density, but I am getting a bit pedantic now since it also affects steel density in my suggested method ).

    Approx. nail count per Kg
    50 x 2.65 - 431 Nails per Kg
    65 x 3.35 - 233 Nails per Kg
    75 x 3.75 - 150 Nails per Kg
    90 x 4.00 - 106 Nails per Kg

    Default THANKS to ALL

    I decided I needed the 15kg of nails even if I needed it or not ... you can never have too many nails!

    The winner is ... 408 nails per kg, Ajax Fastners 2.8mm x 50mm, bright bullethead ... and of course made in China with a humidty today of 87%!

    THANKS EVERYONE ... I didn't realise the humour you can get out of the weight of nails!!!!

    ..and 998 Kg per m^3 at 20 deg C (0.2% error). So yes, being pedantic

    Thumbs down

    Don't forget to allow for the differences in magnetic anomaly in your area. That will affect your real mass. That could make a huge difference that will make your Eucldian Geometry pale into insignificance.
