Just rotated my motor out to change the rocker box gaskets, my rear cylinder is leaking and figured I would change out the front as well. Going by the book, I started to torque the screws back on the rear. Lucky for me, as I was doing my final pass to full torque, a screw sheared! After freaking out, actually getting a reversal bit to work, flushing with oil and cleaning out every spec I could see with a magnet or Qtip, I felt fairly confident I could close it back up.
My question is, with needing a new screw, is there a better screw to use? Stainless (I'm assuming with the cover being aluminum, no matter what I use would have galvanic corrosion)? Stay with the socket head cap screw or use a hex head cap screw? Has anyone used some sort of locking screw, like a stage 8 for these, or switched to a wire-lock cap screw?

I may be a bit unadventurous...but I tend to stick as close to stock as possible when it comes to these kinds of things unless there is a very good reason not to. Glad that you were able to get the old screw back out and there appears to be no further damage!

Typical stainless is a very poor choice. It galls and shears easily. The only real advantage to stainless is the anti-corrosion properties.

Just buy new ones. I had the same problem and replaced as many as I could buy.
