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.
PNEUMATIC FASTENING
James Hardie products can be hand nailed
or fastened with a pneumatic tool.
Pneumatic fastening is highly recommend-
ed. 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).
