plywood floor.. screws or bolts

[LDB]

When attaching the plywood floor would it be wise to put a bead of adhesive along each raised rail/segment/rib/whatever the plywood lays on? Along with that is it better to use screws or nuts/bolts? How many in total? Where do you put them on the sheet?

I don't know if it'd be wise to put a bead of adhesive down. It wouldn't necessarily be unwise, tho. Mainly, it won't matter one way or the other, until it comes to time to remove the decking, should you ever decide to do that. Adhesive just adds one more thing you gotta deal with, before and after. The screws will hold the plywood deck down just fine without the adhesive, and if for some reason the screws don't hold because of a moron forklift operator, adhesive won't help.

As for how many, see the other thread.

My floor no screws or bolts two rows of e-track spot welded to the floor and wood surrounding it held in place with liquid nails no problems in 6 years

I see several different liquid nails products. Which one did you use?

I would only use liquid nails if I never intended to remove the plywood. As one of our members said "don't complicate the simple."

I don't intend to ever remove the plywood, I can't remember what we used other than it was a commercial grade adhesvie, its tan in color if that helps

use a screw with as many threads per inch you can get. compare the self tapper to a deck screw. double the threads. you want them to have a good bite. i tried a regular self tap and the boards will bounce up. bassically they will not let the floor move but not tightened down. the alloc does the job there along with the cargo walls.
