  • Alloy for aluminum bolts?

    Refurbishing a Navy small genset, I was surprised to discover the bolts used to hold down the motor were aluminum.

    The nuts were ALSO aluminum, which surprised me quite a bit, due to galling concerns.


    What alloy would be used for such?

    2000 series, probably 2024 unless it was anodized. 2024 doesn't anodize well.

    7000 series is also a possibilty.

      bolts

      Are you sure they are aluminum? Could they be titanium?
      The difficult done right away. the impossible takes a little time.

        2024 and 5086,the 5086 is the choice for salt water.I have sold a lot of 5086 bolts and studs over the years to the local boat yards.

          Definitely aluminum, too light for anything else. Ridiculously light, I noticed it because they 'felt wrong".....

          Quite reasonably hard, also, but nuts are somewhat marred-up by lockwashers.

          There wasn't any galling noticeable, but then the area was pretty well oiled, so it might have been prevented.
