Help please - deck fixing terminology

I've found a few countersunk externally and internally threaded fixings which I would like to try and use as temporary deck fixings on my new rib.

Trouble is I only have zinc plated mild steel M6 ones and I would like to try and source M8 or M10 stainless steel ones. I am struggling to find any as I haven't got a clue what they are called!!

Does anyone know what they are? See pictures!

Also does anyone know where to get them in A4 / 316 stainless?

Alternatively does anyone know of any different flush deck fixings I could try using to temporarily fit items such as a bottle rack, bench seat etc?

Thanks!

I found some 304 grade threaded inserts which are now holding my A frame to the deck. I covered them in epoxy before I fitted them , to help seal around the thread and give a little extra stick. Be wary that the weak point will still be the deck and not the internal threaded hole. I'd be wary attaching seating down with them to be honest, although I have no evidence to suggest they aren't up to the job.

phil

there are some that are like plaster board fixings the outer is split into 4 with a bolt through, nut on the bottom as you do it up it compresses the outer to form a 4 prong star inside the top is slightly wider that the hole so stays in place when you take the bolt out i am buggered what you call them though shouldn't be hard to find.
hollow wall anchors might be called something else in stainless
cheers

Cheers all for helpful input and suggestions, going to go and do some more research now. Will try and remember to update this post in a few months time when I've bought and tested some fixings.
