2005 Yukon Denali, 2nd row seat tilt adjuster handles need replaced. Someone put self tapping screws in to hold them in. What screw is correct?

If no one else is able to help, I can go take a picture of mine. Ultimately, however, it just needs to fit through the handle and expand the the space behind the handle to hold everything in place.
