As I am not a qualified builder I can't comment with authority. I have asked myself the same question. I have read over the net about the use of these connectors but where I live they don't appear to have reached the building supply outlets where they can picked up off the shelf by the builder. I would say most homeowners wouldn't be aware of them. Can you clarify how the connector holds on the side of the timber as if it requires hammering in only the timber predominantly here is harwood which is just that very hard and needs to be drilled first and then hand hammered. I am not involved with the initial construction but somewhere down the line in the decks life. I would guess that it is a question of both time and costs for both the builder and client. Perhaps the best method that I have come across is a stainless steel screw
8g 50mm long. It isn't going to pop up for a very long time if ever.
It would be great if someone on the Forum could give us a clearer version of this topic.
