I bought (stupid in hindsight) these plusnuts (cross nuts) on Amazon 1/4-20 .280. With the intention of using them in the hex shaped holes in the horizontal supports of my van. Bottom line is the van metal is too thin. I broke my tool. They all spin.
I purchased because they were recommended but I have not found one that sticks. So I am going to have to drill out the ones I did put in and come up with a different solution. Who thinks a crush washer or fender washer might work? It would of course be on the front side of the van metal. But maybe provide enough thickness for things to grab?

Do most people just use sheet metal screws self-tapping?

Thanks!

Take a look at this thread.

They make hex rivnuts that fit the hex holes and do not spin. If your hex holes get chewed up when you drive them out, one solution would be to drill them out to the next larger rivnut or plusnut size and use a round one.

Haven't used sheet metal screws or lathe screws yet, but many people on the forum report they have success with them. I don't think they put much of a load on them, however.

I've bolted in and unbolted a temporary bed platform support rail (still experimenting with bed height/configurations). So far, they are holding well.
