Do not overtighten!
I'm not sure what the torque rating of these screws is, but you can over-tighten them, which may lead to disaster. I had the head on my 550 SX explode in mid flight when one of these snapped off inside the spindle shaft. (I found the spindle shaft with the broken-off screw in there, so it wasn't because the screw backed out). I was running the stock pinion, so overspeed is not the issue. I had tightened them hand-tight, but pretty tight, as I kept having them back out on me every 10 or 20 flights, yes even with loctite (blue). Make sure you get a good loctite bond and don't succumb to the temptation to torque them down to get them to stay. If I find a higher torque replacement, I'll update the review...
