Installation Guide

fastener choices
Use aluminum, galvanized steel or other corrosion-resistant nails,
staples or screws when installing vinyl siding. Aluminum trim pieces
require aluminum or stainless steel fasteners.
Nails
Nail heads should be 5/16˝ minimum
in diameter. Shank should be 1/8˝ in
diameter.
Minimum nail lengths are as
follows:
• 1 1/2˝ for general use
• 2˝ for residing
• 1˝ to 1 1/2˝ for trim
Screw Fasteners
Screw fasteners can be used if the
screws do not restrict the normal
expansion and contraction movement
of the vinyl siding panel on the wall.
Screws must be centered in the slot
with a minimum 1/32˝ space between
the screw head and the vinyl.
Screws should be:
• Size #8, truss head or
pan head.
• Corrosion-resistant, self-tapping
sheet metal type.
Staples
If staples are being used instead of
nails or screws, they must be:
• Not less than 16-gauge
semi-flattened to an elliptical
cross-section (Fig. 1).
• Wide enough in the crown to allow
free movement of the siding.
• 1/32˝ clearance between staple
crown and nailing hem of the
siding panel. Make sure to adjust
staple gap to allow for 1/32˝
clearance.
