GENERAL FASTENING REQUIREMENTS
Fasteners must be corrosion resistant, galvanized, or stainless steel. Electro-galvanized
are acceptable but may exhibit premature corrosion. James Hardie recommends the
use of quality, hot-dipped galvanized nails. James Hardie is not responsible for the
corrosion resistance of fasteners. Stainless steel fasteners are recommended when
installing James Hardie
®
products near the ocean, large bodies of water, or in very
humid climates.
Manufacturers of ACQ and CA preservative-treated wood recommend spacer materials
or other physical barriers to prevent direct contact of ACQ or CA preservative-treated
wood and aluminum products. Fasteners used to attach HardieTrim Tabs to preserva-
tive-treated wood shall be of hot dipped zinc-coated galvanized steel or stainless steel
and in accordance to 2009 IRC R317.3 or 2009 IBC 2304.9.5
• Consult applicable product evaluation or listing for correct fasteners type and
placement to achieve specified design wind loads.
• NOTE: Published wind loads may not be applicable to all areas where Local Building
Codes have specific jurisdiction. Consult James Hardie Technical Services if you are
unsure of applicable compliance documentation.
• Drive fasteners perpendicular to siding and framing.
• Fastener heads should fit snug against siding (no air space).
• NOTE: Whenever a structural member is present, HardiePlank should be fastened with
even spacing to the structural member. The tables allowing direct to OSB or plywood
should only be used when traditional framing is not available.
• Do not use aluminum fasteners, staples, or clipped head nails.

• For wood frame construction a minimum 4d common nails spaced 8" o.c. at panel
edges and intermediate framing members spaced up to 24" on center are suitable
in most locations*.
• For conventional 20-16 ga steel frame construction a minimum No. 8-18 x 0.323"
HD x 1" long ribbed bugle screws spaced 6" o.c. at panel edges and intermediate
framing members spaced up to 24" on center are suitable in most locations*.
FASTENER REQUIREMENTS
Because of the volume of water that can pour down a sloped roof, one of the most
critical flashing details occurs where a roof intersects a sidewall. The roof must be
flashed with step flashing. Where the roof terminates, install a kickout to deflect
water away from the siding.
It is best to install a self-adhering membrane on the wall before the subfascia and
trim boards are nailed in place, and then come back to install the kickout.
Figure 6, Kickout Flashing
**
To prevent water from dumping behind the siding
and the end of the roof intersection, install a "kickout" as required by IRC code
R905.2.8.3 : “...flashing shall be a min. of 4" high and 4" wide.” James Hardie
recommends the kickout be angled between 100° - 110° to maximize water
deflection.
KICKOUT FLASHING
PNEUMATIC FASTENING
James Hardie products can be hand nailed or fastened with a pneumatic tool.
Pneumatic fastening is highly recommended. Set air pressure so that the
fastener is driven snug with the surface of the siding. A flush mount attachment
on the pneumatic tool is recommended. This will help control the depth the nail
is driven. If setting the nail depth proves difficult, choose a setting that under
drives the nail. (Drive under driven nails snug with a smooth faced hammer -
Does not apply for installation to steel framing).
