How to attach to house?

[Richard]

I think this is something similar to what the OP was referring to - "12" long "log screws". Threaded 2-3 inches on the tip, rest is shaft.":

Some comments:

1. Apologies for disappearing.... I drive 1-2 hours each way for work and have long days sometimes. I get home and am bushed. I'm not ignoring (I never like it when someone asks something then never returns to update or clarify)
2. The screws are much like the ones referenced above however, if memory serves me, they don't have a "bolt" type head....but rather they are flat on top and as I recall, use either a square drive or star or other to drive them in (not that it terribly matters) The picture in this comment are almost exactly identical.
3. If you look at the very top in my first picture, there are two screws going through. They, being 12" are indeed going into the banding. That banding is as I recall, two 2x12's structurally with a 1x12 around the outer edge so it would match rest of (log) house. Lower part has two more of these screws and they are again, 12" long....going THROUGH the (if I recall) four inch thick wood so essentially eight inches is going into the blocks. Then, you have the angled support and it also has two screws. Those are driven in at an angle. They are holding the angled support piece and again, being 12" long, are also long enough to go into the blocks.

So the only ones that are not going literally into any type of block material, are the two at the very top. All others do go into blocks. Wife isn't going to go for the tapcon's.....won't want the blue when she's got these (again, rememeber, I'm happy if we NEVER do this as I'm never a fan of putting holes into blocks like these)

Given that, I do have to admit, the side of house with this awning DOES look a bit nicer than the other side of the house.... but that doesn't deter me. The only reason I'm doing this is she wants it done (and her father gave us the land to build on so I view this more as 'her' house than ours.... never mind we've been together for 36 years)

I think the color of what we have is black, but these look like what they are. (might be different brand)

This said (now that I've pasted the picture) the point on below is different. The point on the ones we have are much like that previous picture. This is to show the flat head.

These are structural blocks. The corners of the house, as I understand, were backfilled with concrete. These aren't near there so these "should" be hollow blocks.

No wood behind. What you see (without recalling measurements) are 4x6 solid "whitewood" (I think they call it). I'm doubting he used any type of adhesive between the wood and blocks.... I'm guessing he drilled into the blocks.

If these are structural, then at least every 4 feet the 'hollow' in the blocks is filled with concrete and rebar, creating a concrete column down to, and attached to, the footer.. Along with the corners and either side of openings like doors. Above the openings should be a metal 'lintel' with the hollows in the blocks above it also concrete filled, and/or, a filled concrete lintel.

To be honest go to your local home depot and ask what they have that would give the highest strength ....

You would trust a home depot employee?

They make Black Tapcons, and I'm sure others have them as well.. Dont know about a full 12", but should be some long enough to grab a good hold of the blocks.

Take one of the old screws out and find the same at the hardware store. The old ones seem to be doing just fine.... no need to reinvent the wheel
