Re: Drive Screw Nails?

[Subject Prev][Subject Next][Thread Prev][Thread Next]
ICC Evaluation Report ER-5699 for Halsteel, Inc drive screw nails states that they are an alternate to 10d common nails when used in vertical shear wall assemblies and horizontal diaphragms specified in Tables 23-II-H and 23-II-I of the 97 UBC.  You can review this two page report at: .
Click on Evaluation reports, then search, and enter "screw drive nails"  or enter the report number.
The only problem I can think of is I don't know how ductile they are compared to common nails.

Are there any problems with "drive screw nails" attaching a WSP diaphragm to 2x or 3x wood framing? The diameter and length of the nail is O.K.
