Each unit is individually oiled and boxed. The threads were rough but a little tape to remove the edge with anti-seize for a minute before installing and they worked fine. I'm not sure if they're durable, but they come in Haas, so it's not like they're holding giant tools or being put under a lot of pressure like a real machine.
