1 inch drywall screws for loading subs and some .5 inch sheet metal screws for floor--just be aware of whats on other side of trunk floor before drilling. if you got the time energy and room for it just drill some holes and actually use small bolts and put lock washers and nuts on the backside.

Yeah, I would recommend stainless steel hex bolts as recommended above...
