Joist Hangers...these look like roofing nails

[Robert Foster]

This mornings deck...all the joist hanger nails at the house ledger look like roofing nails to me...is there anyway I'm seeing this incorrectly? Do they look like roofing nails to you?

Very possible! You may need to look at the joist hangers too. They may be undersized for the joist they are supporting.

They're not hanger nails that I've ever seen.... and those hangers look like 2X6 max (can't tell for sure) and the joists are 2X8??

I think they are roofing nails! I would call them out as improper nails or fasteners for the joist hangers and let the powers to be prove me wrong.

They (Simpson) makes hanger nails which are short and do not go all the way through the joist, however, ... those nails basically look like 10d or 12d common nails cut off to 1-1/2" long ... meaning the heads are regular size and regular thickness.

THOSE nails in the photos do look like roofing nails with that wide and thin head.

Did you also notice the toe nails?

[Robert Foster]

Yes, I noticed the toe nails, which may, when combined with the improper nails used in the under sized hangers provide sufficient connection, but I'm not going to make that call. I assume once a component is brought into the project it needs to be installed PMI.

Thanks for the replies.
