I am going to try predrilling the holes, slighty over size of the major diameter of the screws, and use cup washers under the flat head screws and see what happens!
I think it is just the torque of driving the screws thru the undrilled plastic, the heads hit, tighten up and cause the material to shift and PUCKER.
Probably best to drive the screws 95 percent of the way in with a drill/driver and the last by hand to avoid over tightening!
Something to do tomorrow!
