Metal Screw to Attach 3/8" Steel Plate to 3" Wood Tread
Metal Screw to Attach 3/8" Steel Plate to 3" Wood Tread
(OP)
I am designing a "floating" staircase which utilizes a 3" solid wood tread on top of a 3/8" steel plate. The client would like to use a flat head self-drilling or self-piercing metal screw that they would attach from the bottom.
I have only been able to find screws that are certified for attachment of wood to steel when the head of the screw is in contact with the wood.
Is anyone familiar with a screw that is certified for the condition noted above?

You don't need a plate that thick. The wood will carry the load.

I have tried it personally on a project.

Silly ideas and details (dare say, stupid ideas and details) haven’t stopped a lot of Archs., clients, owners, and many engineers too, from doing really dumb things. Remember, most of the former aren’t engineers and too many of the latter aren’t either. They have a computer program, and that’s about all, and that hardly makes them thinking or knowledgeable engineers on any given problem. The client probably got suckered into buying a box of those screws, they didn’t work too good for the first project, so now he wants to use them up. Flat headed screws? Are they self counter sinking too? Drill and countersink the damn plates. A fab shop/machine shop will drill and countersink the holes faster than the time wasted debating here. Then use real wood screws that you can count on. It will cost the client something but nowhere near the time wasted farting around with his original idea, on the job site.

Why not punch holes in the steel tread plates for the wood screws in the shop before you assemble the staircase ?

You are judged not by what you know, but by what you can do.
