I'm trying to fix a 3in square wooden post to a brick wall, using two "Projecting Rawbolts" from Rawplug. These have a portion about 4.5cm long, which goes into a 12mm hole in the wall. The bolt then has an extending portion about 7cm long (in my case), to go through the post.
According to the picture documentation, one is meant to but the bolts into the wall and attach the post though holes in the correct places, and then tighten the nuts on the outside of the post.
It seems to me more logical to tighten the nuts _before_ fixing the post, leaving the bolts securely fixed in the wall. The post can then be added, and additional nuts added on the outside.
Has anyone used these bolts, and can advise me for or against what I suggest? If so, I would be most grateful to learn of your experience.
