This showed up at exactly the right time.
I can't work out how much a bag of 100 of 3.5" screws weighs. The Amazon.com page says that _shipping weight_ is 0.8 ounces, which I guess is the one I should be using if it's going to be delivered to a forwarding service. Does that sound about right?
But if you look at the 2.5" screws at
https://www.amazon.com/Supermicro-Screw-Label-Swap-Tray/dp/B0038KU1YO/ the specs say shipping weight is 0.32 ounces but the the item weight is a whopping 5.6 ounces!! What's going on here? I can't find any reliable information anywhere, and I can't find these in the Supermicro catalog either.
I'm thinking I should order five bags of each, deliver them to the forwarding service, and hope that forwarding them to the UK won't break the bank. Otherwise I don't know because I have reliable information to base my decision on. Any ideas?
