Strap buttons come loose when using grolsch washers

ICBM

If the Grolsch washer is capable of turning the screw via the button and loosening it, then the screw is not tight enough in the wood to guarantee it won't work loose and fall out anyway - I would fix the problem rather than avoiding it, if that makes sense...

One problem is that many strap button screws are too small - both too narrow and too short - to really grip the wood properly. I very often replace them with larger ones - it's surprising how much larger a screw you can get through most standard strap buttons, compare to the supplied ones.

5 years of regular playing and gigging since I came up with my solution and the screw hasn't fallen out yet, i'm taking that as the problem being fixed.

Being me, I would do both!

But then I probably see a disproportionate number of the guitars where the screws pull out, being a repairer. It is often still quite worrying how small a screw many manufacturers think is good enough, given what it has to hold.
