When I reattached the trim on the right side of my TC after rebuilding the right rear due to a leaky window, I discarded all the robertson screws.
I replaced them with stainless steel, #9, pan head, torx screws, where the head was painted white. They also had neoprene seals fused to the stainless steel washer. Purchase both 1" and 1.5" versions from
Best Materials online. Torx heads are way easier to install and remove than the robertson screw tapered square recess.
Went with #9 for a tighter fit, in the existing holes, where #8 screws were previously used. The seals make for a more water tight connection than the existing original pan heads, especially those screws that were not aligned well when the manufacturer installed them.
