Cantilever screws at 1/2: stucco Gap
Cantilever screws at 1/2: stucco Gap
(OP)
Does anybody have a good design example of bending of a screw at a stucco gap.
I've always calculated fb= v/a+ M/S
for a reduced circular section, which very rarely calculates for anything less than a 3/8" anchor.
Commonly contractors want 1/4-20 screws, any advice on how to make it work?
Thanks

As an aside, from a waterproofing perspective it's generally a bad idea to screw through the stucco. The stucco really should be removed, a ledger hard mounted to the framing and proper flashing installed. Screwing through the stucco is a recipe for a leak in my opinion.
If this is for a deck installation, I personally would not allow the stucco to be between the ledger and the framing. I would require removal.

If you continue as you are apparently thinking, you will increase your liability tremendously!

1/4-20 screws are usually not very high strength....certainly not in the range of TapCons. If you have stucco that is at the thickness required by code, I doubt you can get them to work at all.
