Drop in Strap Locks for Stingray Specials

I am looking to install a strap lock system on my new Special, but ideally I’m looking for a set that does not change the existing strap button hole i.e. can be used with the same screw, or a screw of equal length/diameter. Anyone know of any? Schaller S Locks is my usual preference, but in the past I have found their built-in screw to be quite chunky and ends up widening the hole, which I’d like to avoid.

Thanks!
