From what I can tell, 8 Penny nails are 2 1/2" long. Charts on the internet back this up.

But I was looking at the nailing guide for this hurricane tie on homedepot.com and it specifies two different 8d nail lengths.

enter image description here

A search on Home Depot does not come up with any 1.5" 8d nails. What's going on here?

  • Those are "joist hanger nails" - same diameter for shear strength, but shorter than standard so you don't have an extra inch trying to come out the other side. – Ecnerwal Apr 28 '20 at 00:19

Standard 8d nails are 2.5" long. Anything else is going to be some sort of special purpose nail such as these:
