To maintain sufficient strength and rigidity in the cap it is preferred to make provision for side ribs which partly or fully enclose each screw head or nut, said ribs preferably having a height measured perpendicular to the cap surface that abuts **the screw underhead** or not in a plane that lies parallel to the screw axis a distance of one half the nominal thread diameter from this axis in a direction towards the big end opening bore said plane being also perpendicular to the plane containing the screw axes, of at least one nominal thread diameter.
... particularly that part which passes through the cap such that the length of the screw shank along its mid-axis between the **underhead** or not and a plane passing perpendicular to the connecting-rod axis ...
