Plug in "plastic stress cracking". It explains the whole thing. In boat work we often drill the hole slightly oversize, wrap the machine screw with 1 or 2 wraps of teflon tape, and set the screw in thickened epoxy. When the epoxy sets the stress is allowed for, and the teflon allows you to back the screw out to install the fitting. Do it all the time in big ocean racers.
