GENERAL FASTENING REQUIREMENTS
Refer to the applicable ESR report online to determine which fastener meets your wind load
design criteria.
Fasteners must be corrosion resistant, galvanized, or stainless steel. Electro-galvanized are
acceptable but may exhibit premature corrosion; use quality, hot-dipped galvanized nails. The
manufacturer makes no warranty or representation with respect to the corrosion resistance or
performance of fasteners. Stainless steel fasteners are recommended when installing James
Hardie products near the ocean, large bodies of water, or in very humid climates.
Note: When utilizing express seam joints, ensure adequate nailable
substrate width is available.
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 preservative-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.
