I made them in ASA to fasten synthetic roof slates for a garden project. This material resists weathering but is also tough and compliant. So it grips the surface well, spreads the screw force and therefore reduces the likelihood of cracking.
Hole Ø 7 mm
Screw Ø 4 mm (used stainless)
Scale item in slicer for other screw sizes
