Hi
I have a fence post that will go up against my house

The old post was not concreted into the house but just screwed in.

The new fence is quite a big bigger.

It is 2.4m and 10cm b 10cm. It will be 1.8m above ground and 60cm below
ground.

It seems silly not to screw this one against the wall as well

Question is how?

Will I need a screw that will go all the way through the post and into the
house? so it will have to be maybe 15cm long, with a wall plug that is 5cm
long

I have heard of hammer in fixings, but can i get one this big and are they
as strong as traditional wall plug method?

I plan of putting in 3 screws, top, middle and bottom.

3x 6" screws sounds about right. Re wallplugs, just put 2 in the one
hole. The screws can probably then be hammered in.

You can always counterbore the hole, i.e. you don't need such a long
screw, you drill a small (screw clearance size) hole right through the
post and then a much bigger hole (bigger than the size of the screw's
head) say half way through the post.

below ground.

I am having difficulty visualizing a "fence" which is 60cm below ground.
If you mean the "post", why put it below ground if it will be screwed to
the wall? You could leave it a few cm above the ground so it does not
rot so soon?

I meant part of the post will/could be below ground.

I am also putting in two other posts nearby so may just concrete in and nail
this one to the house, or I may just cut it shorter and nail it in only.

Very very good idea and pretty much perfect.

Any tips on how big a screw you would use for a 10cm post ?

No point in concreting it in, extra work gor no benefit & it will rot. Just
fix it to the wall, these work well with a suitable counterbore

You wouldn't use screws, you would use Rawlbolts - 8 or 10mm. No need
to counter-bore, just use threaded rod in the Rawlbolt, with a nut.

Look for frame fixings, which are designed to fix door and window frames
e.g.

http://www.screwfix.com/prods/15978/...5mm-Pack-of-10

You will probably need to counterbore, as they are not really designed for
100mm timber. AIUI the masonry hole should be the length of the threaded
part. IME they are superior to screws in wall plugs.

If there is to be gate hung that will close against this post, I would
concrete a post in independently rather than screwing it to the wall.
This will stop the noise of a slamming gate being transmitted into the house
fabric.
Otherwise - what they said.

I had a similar situation. I used M6 screwed studding fixed into the wall
by Rawl R-Kem cement.

I wouldnt counterbore myself, it just adds rot vulnerability and is
more work.

How big? 6"

Id make bloody great holes in the wall, and use coach bolts, with a
'rawlplug' made out of car body filler.

Something like that?

How do you install them?

Do they work like normal wall plugs? i.e get bigger as the 'screw' goes in?

yes, theyre expanding anchors. You'd need to be in a high wind area to
justify those though.

That sort of idea, except I think in that version the threaded stud is
fixed to the stud, made as one piece - fine if the thread is long
enough. If not, get the type with a bolt rather than a stud and use
some threaded rod plus a nut in place of the bolt.

These would work with threaded rod...

http://www.screwfix.com/prods/20828/...OSFFQ?ts=01677

How do you install them?

The way they work is....

You drill a suitable hole, push the Rawlbolt in the tighten it up. The
process of tightening pulls the wedge shaped end into the sleeve
section, causing the sleeve to expand in the deepest part of the hole.

In the type intended for a bolt, the wedge part is a threaded nut.
Using these with threaded rod, you would insert the Rawlbolt in the
hole with the supplied bolt, tighten the bolt up enough to wedge
Rawbolt in place then remove the bolt to replace it with your threaded
rod. Doing it that way your threaded rod can be whatever length you
might need.

Do all three or four fixings first, then drill and fit your fence post
over the protruding threads.



Do they work like normal wall plugs? i.e get bigger as the 'screw' goes in?

Yes, but a much bigger and stronger fixing. A wall plug and screw tends
to expand most nearest the surface, whereas a Rawbolt's greatest
expansion is in the deepest part of the hole.
