Loose straplok screw

[Joshua Phelps]

On one of my bsr shaped smiths the front strap screw loosens up very quickly after its been tightened. The threads on both the wood (walnut) & screw are perfect & when you tighten the screw all the way you can feel it tighten snugly into place without feeling like its going to strip. I know about the wood glue & toothpick trick to dowel the hole & redrill it but was wondering what other smith users would recommend. I was thinking about some very thin shaved slivers of toothpick in the hole with NO glue might do the trick & also not be permenent.
