Is there an expanding threaded insert for concrete where the bolts removable
I would like to sink some threaded inserts into my garage floor then drop some bolts through the bottom edge of the garage door to pin it down from
the inside.
Is there an expanding insert that's designed for removable bolts, some threaded insert that I can drill a hole in the floor, drop it in then
crane it up tight and it stays tight when the bolts removed. I will probably just have a couple of wingbolts that go though some box in the bottom
edge of the door.
Its just to slow down the scroats that seem to crow bar up the bottom edge of garage doors until they can get a jack under it.

Can't think of anything apart from rawlbolts - which might come loose when the bolt is removed - perhaps you could araldite it in?
I would have thought that threaded inserts in the floor would gradually fill with crud and then not work any more.
How about a fold down hasp arrangement or one of those garage defender things?

Scaffolding anchors? They're M16 but the coarse thread should be a bit less prone to clogging with crap.
Fischer ones are available from screwfix with the setting tool.

I used Fischer fixings for some pretty decent strength wall fixings, they were fairly easy to install and they work well for repeated use. Well, until
the threads got mucky from the brickwork dust (as Mookaloid describes), then they started to struggle. SDS drill into the wall to the required size,
drop an anchor in and then a few thumps with the setting tool. They didn't budge at all.
I got a box of fixings with the compatible setting tool from Screwfix, but at the moment I can only see the fixings separate from the tool. These are
the types of fixings I used;

If they clog up, blow them out with an airline.

^^^^ This, absolutely. Used an equivalent product myself to hang the sun screen to the rear of the house. Solid as a rock and removable.

With regards to the clogging-up, when the bolts are out, just pop rubber bungs in there that would solve that issue I would think (assuming I am
visualising correctly what you are trying to do  )
It looks like the Midget is winning at the moment......

No need to rubber bungs, just refit the bolts, that way the threads stay clean and you never lose your fasteners.

That creates a lovely trip hazard though.
