This specifically applies to my SE one, but it applies to every guitar I own. The front strap button screw can work loose after stage antics and come completely out. I've come so close a couple of times that it scared me into making changes 4 different times on that guitar. The stock screw is fine until you install a Schaller strap lock that rotates in the socket when you move the guitar around. So I replaced the stock one with a USA screw that's 1/4" longer. No good. Then I used a 1-3/4" coarse thread drywall screw, ground down the diameter of the head and applied wood glue. Still backed out. I realized that the problem was from the strap button making direct contact with the screw head, forcing it to back out as it rotated. So I went this route...
That's a 2-1/4" finishing screw w/ phosphate coating. If this backs out, I'm at a loss. I'll report back after the next gig this weekend.
