We recommend #7, 2¼-inch stainless steel trim head screws for
the decking and railing. Some parts of the railing require #8, 3-inch
stainless steel trim head screws. If you do not want the screw heads
to show on the deck boards use the following technique:
Step 1:
Using a #7, 2¼-inch
stainless steel trim head screw,
countersink the screw into the
decking material approximately
¼ of an inch.
Step 2:
Using your thumb,
lightly push the displaced
decking material over the hole
left by the trim head screw.
Step 3:
Tap with a hammer, this
will cover the trim head screw
with decking material.
