Arrow Trailer decking coming loose.

This week I noticed one of my boards has popped up from the trailer bed. No biggie, I just pushed it back down. But it seems the "nails" use to go through the steel cross frame members have loosened. Are those special nails and how does one replace or fix this condition?
Also how does one go about replacing a board or two on a trail like this? They seem to be locked in from either end of the trailer angle iron. See pics.

This board is raise slightly because the nails have worked loose from underneath


The nails that fasten deck to frame

Tow side. Deck is locked in on both ends. How do you replace when boards begin rot or break?

Back side

I would replace the old nails with bolts with nuts. What does the head of these nails look like? Maybe could drive them back up through the board from the bottom, then pull them the rest of the way out. If not just drill new holes for your new bolts.
Yes the back angle would have to be removed so you could change an entire board. Plus getting the nails, screws or bolts out of the broken board.

On my trailer the boards were screwed in with self tapping screws. And my boards were cut just short enough to be slid forward enough to clear the angle iron, when you remove all the nails from one of the boards you can try sliding the board one way or the other to remove it.

Ron, good point . There just be enough slack to allow for that.
Daeyeben, Yea I think they can be hammered out. They look like there is flat on the end that is suppose to hold tight to the framing. Wonder how they were attached at the factory. I like the idea of bolts and nuts but I'd have to drill a lot of wood and metal. I wonder if there is a "nail-screw" that can fit in the existing holes?

You can nail boards using a powder nailer. The type that takes a .22 or .25 powder cartridge and a special hardened nail. I don't know of a threaded fastener that can be "shot". Then there are self tapping screws. Other than that it's drilling and nuts & bolts.

Had this happen on one of our trailers when I was doing landscaping work.
My boss was a former mechanical engineer- he got a caliper, measured the nail, then went back to HIS tool box (the toolbox we didn't dare to touch) and spun a die onto the nail, clamped on a vise-grip to keep the nail from rotating, then used a strap wrench to turn the die and cut threads into the lower portion of the nail. Added a spacer, a lock washer, a nut, then a nylon nut.
"a nail is just a naked bolt, you only have to cut some threads..."

When I redid my trailer I used self-tapping screws. Works great and they haven't loosened up at all.

Do you remember what size you used? Where they stainless, aluminum or brass?

I used them to attach treated 2x10s They are 2 3/4" #3 phillips #12 made by Teks. https://www.homedepot.com/p/Teks-12-...1384/100145370 The package says they are designed to drill through 18 - 1/4" metal. I think I was drilling into 3/16" steel and it drilled quite quickly using a cordless impact driver.
