Attaching ABS armor Via bolts

I've decided to go with the bolts to mount my armor to my vest. i have FP armor ordered...any suggestions on how to attach the bolts to the ABS? i dont want to use a glue or epoxy that will warp or damage the plastic and be visable on the outside. Is there a specific brand anyone thinks may be the best bet for this type of application? i want to get everything i need so once the armor arrives, i can get to work!:)

i've never had plumber's epoxy warp plastic. i haven't tried this specific application, but i've used the putty on a bunch of plastics happily.

I used JB weld.

Thanks guys,im sure one of these will work perfect!
