Just "test run" your screw into the receiver hole without the grip in place and see/sense it's tightness (or lack thereof) before installation. This might mitigate some of the holding potential of the nylon patch, but will give you the assurance you are not cross-threading or running into a hole that is not threaded all the way through.
And since the grips are all some sort of plastic which will compresses to some degree over time, recheck the screw's tightness periodically.
I also like to use the largest thick washer I can fit inside the grip under the screw head to help spread the torque; and unless I have no other choice, I use a stainless steel Allen Head screw which is easier to install than the slotted standard screw.
Once installed, check under the trigger to insure the screw does not protrude into the lower receiver void.
