Adhering to these spacing parameters will:
• Promote proper drainage and ventilation
• Aid in the removal of organic debris
• Meet board spacing requirements for Fiberon warranty

Surface Fasteners
The use of stainless steel composite deck screws is strongly
recommended. Approved coated composite fasteners may
also be used. Plain, galvanized surface fasteners are not
recommended. Pre-drilling is
recommended.
Screw heads must be
ush with board surface.
Use caution to avoid over-
tightening fasteners. Excess
tightening may cause
immediate or eventual
cracking of the fastener
locations.
Do not surface fasten within

" (4 cm) of the end of a
board or 1" (3 cm) from the side of the board.
Pre-drilling
1. It is necessary to pre-drill end of board screw holes
to prevent immediate or eventual end splitting (Figure 6).
2. Pre-drilling all holes will result in better looking nished
projects. DO NOT over-tighten fasteners. Over-tightening will
induce cracking at board ends.
3. Surface fasteners should always be driven in at a 90˚
angle to the decking surface. Toe-nailing screws is not
recommended (Figure 7). Instead, the placement of an
additional joist, when needed, is recommended to allow
perpendicular installation of surface fasteners at board ends
(Figure 8).
4. Pre-drilling is required in cold temperatures.
Requirements
Clean, straight lines of fasteners look better than wobbly
lines. Use white chalk, straight boards or string lines as
templates for straight lines.
All brands of Fiberon decking may be surface fastened.
Annular thread, ring shank and spiral shank nails, of
sufcient length, have excellent holding power and produce
good results.
Screws have superior holding power. Conventional bugle
head decking screws produce solid connections but have a
tendency to cause mushrooming.
For a cleaner look, stainless steel composite screws are
recommended. These screws are engineered specically to
work with composite decking and prevent mushrooming,
resulting in better looking nished projects.
Fastening Boards
Fiberon decking requires two fasteners at every joist location
(Figure 9). While surface fastening is allowed on all Fiberon
decking products, the use of FIberon branded Phantom
Hidden Fasteners are highly recommended with Fiberon
grooved (GV) decking to create a smooth, unblemished,
decking surface. Fiberon GV boards cannot be used as stair
treads.
Hidden Fasteners
FASTENERS RECOMMENDED FOR USE WITH
FIBERON GV DECKING include Phantom Hidden
Fasteners and Phantom End Clip Hidden Fasteners.
