XPL stand mounting screws

[wkjeffers]

does anyone know the screw size/type that mount xpl 90 and xpl 200 to their factory stands? looks like metal threads are in the speaker so i need to match the threads.

Tech sheet (https://manuals.harman.com/JBL/HOM/Technical%20Sheet/XPL200a%20ts.pdf) shows: No. 8 x 1-1/4" FLHD PH
That should be a #8 bolt with Phillips head 1-1/4 in length. I'd buy a #8 from your local hardware store and try, gently, to see if it fits your insert.
JBL part number is: 67375

(Google search seems to indicate a wood screw, not a threaded bolt—which doesn't mean that's what it is.
Is it possible you're looking at the inserts for the leveling legs? )
