I'm trying to hang a sliding glass door. It runs on a heavy metal bar
which is attached to the wall at 4 points. The kit provides 4 screw-in
fastenings which have an M8 threaded section which sticks out of the
wall and the bar bolts to.

I've used 12 mm sized plastic plugs as per the instructions but my
drill turned out to be slightly bent so my holes are sloppy and not
too accurate either. They are drilled either into a concrete lintel or
into concrete blocks.

How do I make this good? I'm thinking along the lines of Rawlbolts
which might be firmer, but how do I ensure that they are correctly
centred?

I think it'd be easier to fill these holes and drill good new holes ...

Otherwise I've successfully used filler, then pressed the rawlfixing in
and letting it all set at the correct alignment before hanging whatever
it is you're hanging.

Start on one hole each end and allow the filler/plug to set properly
such that you can hang the bar, albeit loosely, then filler-up the
other holes, press in *the plugs and hang the bar again loosely onto
them, so it aligns itself until set before tightening all up solidly ..


Depends on the filler setting and/or curing time, obviously, but this
can take a couple of days to do properly.

Many thanks. This is a new technique for me.
