Worse yet, when the screws are over tightened they strip the softer aluminum threads in the primary cover. Maybe not the first time, but repeated over tightening will get them sooner or later.
 
Why would you want stronger than grade 8 with specs that call for 25 - 35 in/lbs? I think damaged screws would be far better than damaged primary cover.
