We are siding a house with cedar. The wall assembly is covered with 1/2″ osb, house wrap, 2″ comfort board 80, and 1′ x 3″ strapping. Is there any info out there about ring shank nails extending through the siding battens (strapping) and not pulling back out in the future?
Key proposals for the next edition of the International Residential Code tackle room sizes, stair specs, emergency egress, and deck guards, among other requirements.

Not sure what the question is. Ring shank nails have more pull out resistance if that's what you're asking. How much? Try to pull one out.

Above indicates this siding maker calls for ring shank nail to be embedded 1.25 inches in solid wood.
(this is for cedar clapbords)

(for shingles) calls for 0.5 inch of nail penetration in solid wood.
Thank you so much UncleMike42. I have never seen that.
UncleMike brought the technical specs and evidence-based protocols; here's some anecdote. I'm residing my place, built in 1977, with cedar shingles. It was sheathed in 5/8" plywood and then had t-111 on it. The t-111 was in pretty decent shape, and I've removed and replaced the sections where there was rot (mostly bottom few inches where capillary action of the water sucked up rain that had shed to the bottom of the sheet). Firing 1 3/4" stainless nails from my Bostitch per cedar council's recommendations. Get an occasional misfire, where there is a second nail that goes in halfway. Usually there is about 3/4" or 1" of the misfired nail sticking out. The point is through the shingle (maybe 1/4" and 3/8" of homeslicker (drainage plane), so at most there is 1/2" of penetration of that misfired nail. They're a bear to get out. I usually have to get a big block and gently pry the nail with a lot of force to budge it. I am always impressed how much holding power those nails can muster. The 2 1/2" stainless trim nails: if I make a mistake and need to pull a board off, I simply start over with a new board because there isn't any getting those out without serious prybar action.
Thank you Mikeljon. i agree. SS ring shanks are a bear to pull out. I spoke with Western Red Cedar assoc. today and, although they said that 1 1/4" penetration into solid wood is what they recommend, they didn't go as far as saying they whole assembly was going to be a failure. Thank you for your insight.
Probably the nails will hold with only the strapping for a nail base IMHOP. Even if a few don't it's not like your house will explode or something other catastrophic.
