RE: staples vs. nails

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Given today's industry standards, it never makes sense to specify any
shearwall nailing with "8d" etc.  The only thing that will guarantee the
performance you seek is nail diameter/staple gauge and length (NER-272
is the answer), as that's often the only information the guy with the
gun can be sure to find on the box.  

NDS provides a translation in their tables for "#d box" to diameter and
length.

Also note that UBC and IBC tables require "common" or "hot-dipped
galvanized box" nails (see footnotes to put it all together).  There are
virtually no manufacturers of gun nails who provide either, so the UBC
is nearly unusable.  An exception is Steelhead for galvanized gun nails

Subject: staples vs. nails


I went to a wood shearwall seminar last night, and remembered a thread
in
the recent past about allowable loads using staples.

To get lots of code-approved values for nails and staples, go get NES
Report
#272, "Power Driven Staples and Nails for Use in All Types of Building
Construction".

http://www.bocai.org/boca-es/pdf/272.pdf

Interesting facts:
 - There are no "standards" covering the penny weight designation.  In
fact,
there are dozens of "8d" nails out there with different strengths,
diameters, lengths, and shapes (smooth, twisted, fluted, etc.).  If you
want
a specific length and diameter, you have to specify them.

 - The building code values are for "common" or "galvanized box" nails.
"Common" nails are RARE in power-driven fasteners.
