PACKED IN OIL! ROUGH!

The whole box was filled with oil. It was so much oil that the sticker with all the sizes of the bolts was long since erased. I have tried to remove the oil from the bolts but it is very difficult to remove from fine threads and hex heads. This is also intentional: instead of packing the screw box in a loose plastic bag with an air hole, it is in an airtight bag. That's how it should be, otherwise the oil would leak everywhere. They knew what they were doing. We strongly recommend avoiding this if you don't mind the cleaning work you need to do.

Pros

12.9 alloy steel with oxidized surface has good tensile strength and corrosion resistance in many environments.

Cons
