MDF Table/Surface weight load

[big-all]

as an aside
if they do work loose you can countersink a nut and bolt in say a couple off places

This is far more complicated than it needs to be, use 16mm long screws as big as will fit in the holes of the leg holes. Use a drill bit about half the size of the overall screw thread size.

All done
