Hi
I am connecting a timber post to the brick wall of my house.
I have got M10 150mm anchor bolts from b and q. I have drilled a counter sinc hole (28mm) in the post which as the moment is too small as the hole won't accept my 17mm socket.
In the middle of this I have drilled a 10mm hole through which the bolt will pass.
I will drill the hole in the wall (16mm) tomorrow, in which the bolt will fit.
As it stands, the bolt will not 'bite' the rawl plug as the countersink hole is too shallow. If I drill a lot deeper will this be a problem or will it not effect anything at all?
Also, how deep should I drill the hole for the rawl plug part of the anchor bolt? Am I meant to drill deeper than the length of the plug, as there is a bit in the middle that allows me to screw the bolt in further?
Lastly, how wide does the counter sinc hole have to be to take my 17mm socket?
Thanks for your help. Sorry if they seem such simple questions... Am new to this!
