I'm in the process of installing a shelving unit to the wall which I've made myself using scaffold tube and brackets, and some nice wooden boards.

It's a bit of an industrial styled unit and has 8 flanges holding it to the wall.

Each flange has 4 bolts, it's a dot and dabbed brick wall and I've been using self tapping masonry star head screws.

This has mostly been going fine but of the 20 or so I've currently fitted a few did not go in properly, likely due to me not cleaning the pilot hole enough, so I've had to take them back out clean the hole up again and try again, though this has now lead to them not biting well and they seem a bit loose in the hole.

As there are so many holding this up I'm not worried about the strength, I'm fairly confident I could hang off this thing (though I haven't tested that).

So I'm just wondering if for piece of mind there's a chemical fixing I could squirt into the holes of the loose one before putting the screws back in?

Someone suggested sticking a plastic plug in the hole which I've no doubt would work, but that would mean removing the other screws and flange to put the plug in, which will lead to the other 3 holes having the same problem..

Any suggestions for a chemical fixing I can squirt into the hole to hold it?

I reckon a squirt of http://www.screwfix.com/p/no-nonsense-polyester-re... or similar, and then re-drive the screws would do the trick.

Be warned though, they're not coming back out without a fight!

Cheers guys, will give the polyester resin a try as I can get some from toolstation on the way home, doesn't look like they stock no nails.
