I've dropped my LP standard so many times due to strap lock failures. Almost dropped it yesterday when I was noodlin' for a few minutes in between meetings.Pretty sure the upper horn on my S2 has the screw glued in. Once a straplock fails you start to check them every time you grab a guitar. Same thing with the washer on the jack
Throw a toothpick or two in with some wood glue, then screw the straplocks in. It'll cure overnight and you'll be golden.
