Anchor fence post to brick wall

[Paul17088071]

Hi all

I am fitting a new gate to the side of my property and am going to anchor a 4x2 fence post into brick. Can anyone recommend the best bolts/screws for this please?

Many thanks

Chemical fixing.
Threaded bold.
Any resin that's cheap and will fit a standard mastic gun.

as wayners says - use a chemical resign and bolts - have now done this on 3 Gates , 1 in the current house - actually used a 4x4" post onto a breeze block wall - the gate rarely gets used
I used some threaded bar 10mm from toolstation

Threaded Bar

Can’t find a standard bolt to fit the job? Choose this M10 threaded bar instead – it comes in a 1m length and is easily cut to your preferred size.The mild steel threaded rod is a simple but reliable solution for achieving a long-lasting fix in custom fastening jobs indoors and outdoors – a...

and just used a fostner Bit to sink the nuts into the post - looked fine

As screwfixx links dont work - used this resign
Easyfix Styrene-Free Polyester Resin 165ml (292PX)

i see screwfix have STUDS 130mm - so depending on how you are mounting the 4x2 100x50 post - they may do if only using the 50mm side - but if fixing the 4" - i would want more than 30mmish in the wall personally - BUT just a DIYer

When I done mine I just used a standard concrete bolt ( screwfix 8215P) which is like a selftapper and cuts it’s way into the brick as you screw it in.
I used a 4x3 fence pole, and drilled the hole for the bolt, then an inch deep countersunk hole big enough for the head of the socket screw. After it was fitted, ( and it’s solid) I screwed a 100mm fence slat over the top of it to cover all the holes

Thanks for your help. This concrete bolt looks great, so you didn’t have to pilot hole into the brickwork prior to screwing this through the timber, and wall?

Silly question, with the resin would you put this on the face of the 4x4 post first, or apply it to the wall and then push the face of the post in to it?

Thanks

the resin goes in the hole in the wall and then the bolt is put in the hole - making sure it all aligns with the post
and then (i leave till next day - usually 18-24hrs later
then put the post onto the bolts and using washer and nut bolt to the wall

i drill the post holes first = so i can then mark the wall
i use a fostner bit to counter sing the hole for the nut
so the resign has nothing to doo with the post

this is the video i watched

Ah fantastic, thanks so much; all makes sense now!

Great help, cheers

I have looked around, and I’m thinking of using the easy fix studs M12 x 160mm with the resin, giving me 60mm into the wall taking into account the 100x100 post.

This would work okay with a 14mm drill piece put into the post and wall?

Many thanks

 

[ETAF]

i would use 12mm hole on the post - so the stud is a good, but free fit in the post, 14mm maybe too much and so its loose in the post - then yep a couple of mm bigger than the bolt in the wall - making sure ALL the dust is remomoved before you use the resign

i think i went in further than 60mm into the wall - a brick and breeze block is about 100mm - so i would have gone in maybe 80/90mm , cant remember - for the 4x4 - BUT less for the 3x3 post i used

I used 10mm bolts
And a fostner bit or a flat bit to make a counter sink for the NUT to set under the post

I like simplesteve suggestion to cover the holes

but in the orginal post - you say

anchor a 4x2 fence post into brick.

are you doing a 4x4 - and do you need 4x4 or would 3x3 post be OK - i guess it depends on how big the gate is

I only used a 4x4 post - because i needed the gate to be away from the wall 4" because of other things in the way - mainly some drain pipe running along the wall

i would have used 3x3 posts i guess

BUT I"M JUST A DIYER - Someone more expert with lots of experience may be along to answer

The ‘ concrete bolt’ system is the opposite to the resin one; with this you drill a hole in the wall SMALLER than the diameter of the bolt, and allow the course chunky thread to cut its way in. The hole in the post can be the same size as the bolt, but you need a countersunk hole big enough to get your socket set in to turn it.
The other main difference between the two is that you don’t need to cut the bolt to length.
Both systems are good !

 

[Paul17088071]

Sorry I meant a 4x4 post. The gate is going to be 2 metres high so would prefer a stronger anchor.

Ah fab, so you’d recommend the 12mm drill piece for M12, the only reason I suggested the 14mm for this is because Screwfix advised on the website to do so, however It makes sense to have a tighter fitting?

Thanks

Great, thanks. If I were to use 120mm concrete bolts through a 100m x 100m fence post, with this countersunk into the post around 20mm, would the 40mm different be enough to anchor it in the brick?

Thanks

 

[simplesteve]

personally I would countersink it 50mm meaning 50 left in the wood and 70 in the wall. Remember the bolt head itself is +10mm ish from your countersunk hole

Many thanks Steve.

Silly question, what tool would I use to screw this through the wood and into the wall?

Would a socket set work?

Thanks
