Countersinking Hex Bolts into Pergola Beam a Good Idea?
I am getting ready to build a 12x12 pergola with a 14x14 overhang in rough cut western red cedar and I want the finished product to be as clean as possible. Here's what I'm using:
The tops of the posts will be notched 1" to allow for half of the beam to sit on the post.
Here's the Question: If I've got 2" of beam, then 4" of post and then 2" of beam, that's 8" to go through with a hex bolt. how deep into the 2x10 beam can I countersink without compromising the integrity of the board? Ideally, I want to be able to countersink then place a plug in each hole to hide all the hardware. I think I'd have to go in at least 1", and I'm worried about that being too much.
Thanks for the replies!
