I remember seeing an article reviewing new Simpson hangers that were invisible and routed unto the ends of beams. It seems like the Simpson ETB 90 is what the article was referencing but i can not find the article. The Simpson ETB90 look like what I need but are only available in Europe? Anybody recall the article or seen the “invisible” beam hanger?

I haven't seen invisible beam hangers, the only ones I've seen were for 6" posts.
But, I went a looked and sure enough, they do make them.

I used them on a patio cover a couple of years ago. The beams I used were to match old, they were 6x8 on 6x6 posts. Threaded rods into posts and the purlins between the 6x8 beams were also 6x8. Where the beams and purlins met was where the Simpson hardware was used. It turned out very nice but was time intensive because the pins that hold the purlins to the beams had to be exact. I found a small drill press type of guide so that the pins were exactly perpendicular to the purlin. We're talking tolerance of 1/32 so that beam to purlin joint was tight. I will say that I would use them again (just maybe charge a little more)
Here are some photos. Apparently they are Danish. Nobody around here will supply them as they are not in the US catalogue. And Simpson could not tell me where to get them either. I guess ill order them from from an international internet sales. I can usually find articles that I have read in the past with a few searches, but this article wont come up?? I have looked in FH, JLC and Pro deck builder, but no luck. Thanks for the replies!
Screws into end grain? Really? Maybe they're not in the U.S catalogue for a reason. (Perhaps code compliance issues?)
yeah I thought the same thing but it looks like the screws go in at an angle. If Simpson makes a bracket with load tables and engineering specs, that is good enough for me.
The only brackets like these I’ve ever seen the bracket is through-bolted to the beam instead of being doweled.
Maybe because they don’t have earthquakes and tornados in most of Europe? Or maybe because they don’t think they can sell enough of them to justify the cost of certification.
