Replacing an insert nut

[ejdes]

Hi all,

During the floods this weekend (Storm Bert) I was bolting my flood barrier to my door frame but I applied too much torque on one bolt, causing the insert nut to come loose. Being loose, it now can't maintain a watertight seal. I should only have done the bolt hand tight - but its funny how stressed you can get when the water is rising.

What would be the best way to fit the insert nut back into the same drilled hole in the wood so that it is secure? It's not an option to drill at a different height, it has to be the existing hole (although it could be filled and re-drilled if necessary).

Thanks in advance.

PS: the flood barrier is this exact type (stock photo, not my actual door!).

Probably 2 part epoxy?

Mix it, then smear inside the hole, then screw the insert nut back in?

Yes.
Maybe fill the internal thread with grease/wax or tinfoil to avoid the internal thread clogging with epoxy.
