The license plate and license light bracket are ready to fall off the rear cap of our motorhome. The screws have become loose. How is the best way to reattach these items to a thin wall (about 1/8 inch thick) with foam insulation behind it? There is just nothing for a screw to sink into. Jackson, (Plano, TX)
The perfect fastener to use in this instance, Jackson, is called a threaded nutsert. Most astute RV repair facilities will have this fastener and its requisite installation tool, especially if they also perform collision repair and other types of RV body work. Nutserts can solve a multitude of mounting and securing issues in aluminum, fiberglass, and other types of thin, RV siding materials. Take a look at this web page for a neat little presentation on how a nutsert is actually installed:All professional RV service technicians will, (should), have access to a professional nutsert tool. Hope this helps!
