These are the sort that I mean:

Would these be suitable? If so which length would I need to get? 120mm?

I fastened two 3x2 posts with three of these (m8x100) on each, and they worked great. I guess I might have used something longer if the post was thicker.

I know that these bolts are good, we use this type all the time for floor fixing.
I've never used them through wood though, but I can't see why there would be a problem.
I would have said try and get at least 50mm into the wall, but you can achieve that with the 120mm bolts if you countersink the hole slightly ( drill out the size of the head) and that will hide the head too.
Why Thunderbolts ? Can you not remove the posts after drilling? I would tend to use a plug into the wall for this application, but if you have to laeve the post in place then use the thunderbolts, I'm definitely not a fan of frame fixings for this type of installation, they tend to come loose.
I assume that you are fixing the posts all the way up their length?

Only reason I was thinking Thunderbolts was I'd read a few people recommend them.
I can remove the post after drilling - would you use something like this to do the job:

It's a 3ft fence so the post won't be particularly long - I was thinking of fixing it at 3 points along its length.
No, They're what I wouldn't use.
They come loose when used on fence posts in my experience anyway.
I'd just use a normal wall fixing plug and contersink the hole about 25-30mm into the post, so that a 100mm scew would do. I like the rawlplug UNO ones, I find them superb in most applications.
But by all means use the thunderbolts, I just wondered why.
Good Luck
