Attaching railing post to deck - lag screw or bolt?

First off, thanks for the help on my deck design. It was approved by the inspector with no issues.

When attaching the railing post, do you reccomend using lag screws or lag bolts?

My deck posts will be installed on the deck's inside and there will be a 2x12 cedar facing board installed on the outer joists to frame in the decking and give it a very clean look. I was going to notch the post bottoms 1.5", so they sit flush with the outer joists outer surface.

I can connect these posts 1 of 2 ways - use a lag screw and attach them directly to the outer joist (or inner joist depending on the their location) or use a counter sinked lag bolt that will fully penetrate the outer joist and the 4x4 deck post.

Since I am facing the outer joists with cedar, the lag bolt end that is facing outwards will not be seen.

Thanks in advance.

Bolts are stronger than screws

Use the bolts - its a much more secure connection that you won't have to worry about.

That's what I thought. Thanks for the clarification.
