Attaching body to frame?

[madjack]

Les, I am sure they are used elsewhere but the first place I saw them was on utility trailers, holding down the deck...and I bought mine at a RedNeckTrl Sup dist...they are hardened, have a blunt end and fine thread with a "tapping" groove in the first few threads...I have seen a bunch in use and don't know if I have ever seen a broken one...rusty and bent...but not broken......

I'm going to use the "torque" deck screws as well.....
While tearing down my donor trailer I noticed this is how they secured the floor down. And there still in there good; had to chip the wood floor out from around them; and although their rusted there still holding! They kinda went overkill on them, so I'll have to grind them off when I put the plywood floor back. I haven't found them locally yet either, since type in "deck screws" brings up regular deck screws...so I might have to order some. There's a local fastenall dealer, but searching the website I came up with the same standard deck screws...

Thanks to all those who replied. I am still in the planning stage and appreciate your input. I am a homebuilder by trade and tend to overbuild everything. I will rethink my floor and wall plan to possibly reduce weight... I will be hauling our tear with a full-size Chevy V8 pickup truck with towing package so the weight really isn't a concern. I will almost always have a motorcycle in the truck bed also. I hope to never need to remove the trailer body from the frame but I would like to have that option. The 2X4 perimeter frame was simply to cover the trailer frame and have plenty of wood to attach the deck and sides.
I am now thinking of using lag bolts through the floor, recessing the heads, epoxying them in and covering with vinyl. To remove will be a simple matter of removing a few nuts and lifting off.
Thanks again for the responses... I will have lots more questions.
