Hello Everyone, I'm building a new screen porch / deck onto my house and my question is how do I secure the post on the deck so that they don't move? All of my post on the screen porch are attached together by a 1x4 and are flush with the band. I've been trying to figure this out for sometime, any help would be greatly appreciated thanks.

I used 4x4 post and mounted inside the rim joist with 2 bolts through the rim joist and post.

Also add blockings on each side to limit lateral movement.



(*ignore the bottom wood piece under the post)

there should be a peice of blocking where the carriage bolts are shown.

the peice of 2x6 or 8 thats on the bottom will act as a water trap which can accelerate rot

If you are building a deck, you may want to check with your local building inspector what code you are under. If you are under the International Residential Code, minimum post size is 6x6 inches. Connection details are clearly shown in the IRC prescriptive deck construction guide, available typically from the building inspector or on line. But you really should start with the building inspector, unless of course you live in an area with no inspector and no code, in which case I would simply follow the 2009 IRC guidelines.

yeah, i was dealing with a 10 footer by myself so i needed a pair of extra hands. that piece has since been removed.

as far as additional blocking behind the post is concerned, any tricks to deal with those bolts sticking out?

Post should have been counter bored so the bolts, nut and washer do not stick out so far.

Thanks Joe.

I did think about counter sinking it but was hesitant about reducing the width.

I still have access from the bottom so I will work up a solution and post back for updates.

Well, OP, you now know what *not* to do :)

It's counter bored not counter sunk. Counter sunk would have a angled hole at the bottom.
Fastest way is using a paddle bit, a forister bit will also work.
