My stuff arrived today has well, wonder if they came on same shipment.? Don't know if dare say this but my stuff is ok but I did have other stuff which supported the screws plus they where only 1300mm long.

Depending how bent then like Jon says V bollock and plenty of force, I've straightened screws before but it's slow process and easy to over do and bend more.
If not too bad then I'd fit on machine and see how they perform, sometimes they can be ok when running and not affect machine too much.?? . . .they can also shake the bastard to bits but worth a try.!!
