Tip for hogged out screw holes on trim or interior

I don't know if this is a common trick or not, but I just stumbled onto it. I was replacing the front wheel well trim on my '69 Malibu and once I got it off I saw a bunch of green rubber material in the screw holes. Turns out it was snips of electrical wire. It soon became clear why: the holes in the fender were either too big from the factory for the stock screws or hogged out over the years. The previous owner had cut 1/2" pieces of electrical wire and stuffed them in there, giving the screw something to bite into and tighten. This had held the wheel well trim for at least 15 years. The principle is sound; I've done similar with toothpicks and wood glue when repairing furniture.

The holes in the fender of my car were too big even for oversize screws to tighten completely, and those screws, even though they'd be kind of out of the way, looked out of place. I tried the electrical wire and it worked great. For the holes facing down, I cut the snips to be about 1" long and bent the tip down like a hockey stick and stuck the long end in there to keep it from falling out. Some of the screws bit mostly into the rubber and tightened down just enough, but some apparently bit into the wire and tightened down as tight they would have into metal holes.

I wouldn't use this trick for anything structural or under stress, but it's great for trim or interior pieces where oversize or non-factory screws would look garish.

By the way, I wound't be upset if someone "hijacked" this thread with unrelated but equally helpful tips or tricks.

I'll keep those in mind for future issues, but I don't think they would've helped with the trim as the lip on the fender isn't wide enough for the one style and the other style might catch on the top of the tire during a turn.

I do appreciate the tip. That's the kind of stuff I'm hoping people will post.

Re: Tip for hogged out screw holes on trim or interior

they work great on fender lips thats why i posted them. way better than stock sheet metal screws. i drill the hole with a #10 bit, deburr and just slide the clip nut in place. use 3/4 10 32 screws. i have them on all 4 fender lip moldings on my 70. you could also use 8 32 s.another aircraft product to keep in mind are nut plates. rivnuts or speed nuts which are basically clip nuts for sheet metal screws

Using .030 welding wire in the door holes where the arm rest base screws go was a common fix in the 80's when
these cars were well worn.

I stand corrected. I'll try those for the next time I need to attach moldings.

wrapping a bread loaf wire tie with the paper on it, around a sheet metal screw, for a too big a hole also works. From Al the machinist. Have to give credit where credit is due.

Re: Tip for hogged out screw holes on trim or interior

as easy as they are to get to in this case you could just use a bit behind the lip

Paper clips. One place they work really good is on the holes that the screws go in that hold the front armrests on. You cut it long enough that when you bend it together you have 2 legs about 1/8" long. You may need 2 if the hole is too big. Insert it in the hole and push the legs over the edge of the hole. Works like a charm and you can pull the door closed without worrying the armrest will come off in your hand.

Well, I'll have to use that trick Hank, as I do have a "wobbly" arm rest. THNX!

Re: Tip for hogged out screw holes on trim or interior

So, are the kinds of clips you and Gary recommended the correct way to attach the molding piece and the electrical wire is just a shade tree jimmy-rig?

Re: Tip for hogged out screw holes on trim or interior

You can also use a small piece of metal (cut up soda can works) if you can get to the back side. My 15 Silverado has several screws holding the bed liner in place. Right after I go it, I saw one laying in the bed. I screwed it back in and called it good. Turns out that it left the Factory with to big a hole.....so I cut a strip about 1/2" wide and 1" long, bent it in half,and half again, took a Awl and punched a hole in the middle....done.

Ideas are like children: there are none so wonderful as your own.

Same as the welding wire I mentioned, bend it in the shape of a fence staple. G bodies were really bad with the pull straps on doors.
