I've had up to 3500mm screws from Fred and never had a bent one yet. To be honest this is why I stopped dealing with Chai at linear motion bearing and went with Fred because his shipping and packaging was much better.
If the screws are relatively long (1500mm+) they come in a wooden packing crate, if say under 1500mm they come in a cardboard box. However, usually it's a very strong thick-wall box and if the screws are over say 1000mm they are supported in the box with Cardboard braces to stop them bending.
Also, Fred wouldn't hesitate to replace or refund if they were bent and wouldn't ask for the old ones returning.

Edit: I will clarify this in that usually when I order from Fred it's for more than one machine worth of parts and often has linear rails etc so my packaging might be made slightly stronger than for say a single machine worth of screws etc. However, I have in the past had small rushed orders and the packaging as been good and strong.
