Help please - deck fixing terminology

[diver 1]

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!

They are called threaded inserts, Google stainless threaded inserts for wood & plastic

Well nuts a nut encapsulated in rubber the nut compresses the rubber into the hole sits flush. Other fixings look on seascrew good supplier prompt delivery.

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.

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

i have a wurth kit that rivets nutserts into holes basically its an internaly threaded tube like a top hat shape you put it into the hole with the top hat brim on the outside and the threaded mandrel pulls the bottom up like a pop rivet I use it loads at work but the nutserts are made of alloy so not sure if this is usefull

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.
