Ring Shank Nails vs. Common
Ring Shank Nails vs. Common
(OP)
Looking to know if the ICC has approved "ring shank" nails as a substitute for common wire nails in structural uses such as shearwalls, roof diaphragms and general wood construction. This is under IBC 2000.





RE: Ring Shank Nails vs. Common
For typical nail sizes used in diaphragms (8d or 10d), I specified ring shank nails in lieu of common nails without any objections from various building departments.
Someone has my 2000 IBC at the moment. Once I get it back, hopefully I can find more information.

Thanks,
You refer to NDS Table 12.3B/C as referring to "ring shank". I don't see that anywhere...only common nails. Where do you see "ring shank"?

Table 23 of ICC-ES/1539 compares the fastening schedule to IRC2003:

Do you think that its proper to allow the substitution if they provide x percent more nails? I wouldn't think so as the diaphragm/shear tables are pretty explicit in their spacing vs. capacities.

The NDS minimum nail penetration is 6D per 2001 NDS 11.1.5.5. The reduction factors given in the NDS Table footnotes only applies to those tables. If one chooses to calculate their value than 6D is the minimum requirement." from Zeno Martin Staff Engineer APA - The Engineered Wood Association
Therefore, the engineer of record should evaluate the substitution using NER-272 (for IBC2000).

Sorry about the delay. I've been away for a few days.
Table 12.3C has the values for "threaded hardened-steel nails" as opposed to 12.3B which is for "common nails" with smooth shanks. Ring shank nails and screw shank nails are both considered hardened steel nails. So far as I can see in the NDS, there are no difference in capacity for different types of threaded nails.
Boo1, thank you for the nice link!
