special floor fastener inserts

hello, i am looking to mount a rear bench seat in my searider 5.4 and wanted to make it easy to remove. ive seen stainless steel inserts that can be screwed into the floor with a female thread that are flush with floor, I have been looking online and dont know what they are called , i cant seem to find them, I am weary of anything that will allow water to start to rot the floor so i will make the inserts permanent, can anyone help me with the name or where i can find them for sale, tks

I know what you're talking about, but can''t remember the name. A friend of mine who does sheet metal knows what they're called; I'll see if I can get in touch with him tomorrow.

We have used that type of threaded insert at very close centres for fixing down the sections of aluminium floor in the Pacific (they were bonded in with epoxy to ensure they were solid and to avoid water ingress into the new plywood). However, i would not rely on them for fixing in a seat which will have a fair amount of leverage and weight on it..... refer to image which shows the sheet in place.... theres about 40 of those in that one sheet alone to make it strong enough.

The big head solution suggested is a good one, but when we looked we needed access beneath the deck (which we didn't have). As such, we had these made up (see thread here: Removeable Jockeys - How??? ) and they are still working very well indeed /solid.....they are regularly used to bolt in heavy survey equipment /seats etc.

Search also 'Nashers' thread as he made some up very similar /for same sort of reason..... Deck Anchor Points.

LTF:

My buddy says the system he uses is made by a company called Avdel; it's a sort of threaded rivet system, he claims it's the next best thing to welding an insert in.

Avdel Threaded Inserts

He says you'll also need the insertion tool at about $25 (or the pneumatic tool at about $500.)

Forgot to mention, he also said there are several similar systems, so if you can't find one that works for you, there may be another mfgr that has a solution.

No access to under deck, and not got the skills or experience to resin bond in, or cut in a small hatch.
