JayLaw, We understand your frustration, though we have used that same screw for a number of years. We used to manually lift all of the engines we rigged here at BCB. We did not use the pump or put power on the engines here. So we have loosened those screws literally hundreds of times. We have never had to replace one. And still we do understand. It takes a large screwdriver, and probably the fact that you have not done this proceddure on very many engines added to the error. We have seen thousands, and have seldom seen one damaged too badly. We do wish they would use a little tab, actually reverse like a screwdriver bit, or even a HEX head. Then you could grab that with a wrench or pliers. You would scuff the end, though it would not strip like the screw head. BCB
