    In wood?  No!

    Don't be a retard!

    Use joist hanger screws of the proper length. Or large enough (long enough), deck screws. That's what I do. I've never had a problem. I don't like nails either. 

    Similarly, use only concrete screws for concrete.

    what are you hanging these joists from?  That's what's critical -- example:  in standard American southern single family construction, the pre-fab trusses [joists, rafters, and posts between them] rest ON TOP OF the concrete block walls.  This because masonry is strong in compression, but fractures under tension.  [the trusses are attached to the header row of the cbs wall with straps fixed in the concrete of the header and double nailed into the trusses.]

    Yes but prefabricated hangers are better. Used with standard screws. See link.

    as long as they are rated at least as strong in both shear strength and pull out as the fasteners you’re supposed to use

    never seen them used for hangers but I have seen the simpson structural screws used

    The type of screw is determined by what you are securing TO, not by what you are hanging.

    if you need screws for joist hangers then they must be different to european hangers ..ours fit in the bed joint of the internal block walls ...and if your talking joist straps they are different but do same job ...but those screws of yours are far bigger than the holes in side of straps ..

      "washer"?  We recently had a deck replaced and all of the joist hangers required nails and they did not use any "washers" on any of the nails.
