And the only instructions for sleeve bolts I could find on the Hilti site clearly show the sleeve passing though the fixture.

Cannot see why there is any difference between sleeve in hanger or sleeve flush with surface.

From my viewing of the manufacturers' sites the staement "generally bolts are made assuming the sleeve is flush" is incorrect. Flush-head bolts don't have the problem of protruding thread but can be difficult to access.
