connect beam to 4x4 post

[PCAnimal]

HI,
i am about to build a small pitched roof timber structure. It has 4x4 posts and is only 3x3. What is the best way to connect the beams on the corners?

I know I could notch 6x6 but those posts were too big for my needs. I am attaching 2x6 as the beam. I was reading that simply bolting it created a sheer weight issue.

I can't notch a 4x4 as i dont think it would leave enough wood behind (unless I am wrong).

Is there a suitable connecting tie?

ANy suggestions please?

I've done similar using m16 threaded bar, can't see that snapping. But use screws/nails first to check it all lines up square before you start drilling holes.

Try and add some sort of diagonal bracing/strapping

Thanks I've never used that before. I assume this would be ok with the appropriate nut?

I was planning on diagonal bracing from the post and use coach bolts at the top because the beam will be proud of the post dimensions (if that makes sense).

Large coach bolts are much more expensive than studding

(You can order it in cut lengths if you want)

I like to use C-form washers to prevent sinking.

Stainless here as coastal.

I built a pergola lean-too using studding.
A beam on the house
Two posts in the ground.
I fixed two timbers, running between the posts, one on each side.
Drilled right through, length of studding, nuts and washers on each side

I normally use square plate washers, they are about 2" square, you can usually get them in m12 or m16.

Most nut & bolts shops do threaded rod in 1m or 2m lengths, and I put a bit of paint on the cut ends to prevent rust.
