Fasteners should be installed perpendicular to the deck surface and driven flush; do not overdrive or splitting will

occur. Always double joists at butt seams.

Do not toe screw deck boards as this will cause splitting.

Square Shouldered Boards

Fastening Methods

TimberTech recommends the use of TimberTech Cortex

or TOPLoc for PRO and EDGE for square shouldered deck

board installations. Pre-drilling is required when within

1-1/2”of the ends of the board and for temperatures below

45 degrees Fahrenheit to avoid splitting and screw shear.

Alternate fasteners are stainless steel or high-quality

coated composite deck screws.*

*Cortex cannot be used on boards with a scalloped bottom, such as

TimberTech PRO Terrain, EDGE Prime+, and EDGE Prime.”

Always be sure to check and cut the factory cut

ends of all boards to ensure they are square.

Any fastener driven through the edge of a

TimberTech PRO, TimberTech EDGE, Reliaboard

should not be used to avoid splitting of the board.

CAMO® Edge Deck Fastener is an example.

of this type of fastener. The use of this type of

fastener voids any warranty provided with Tim-

berTech Decking.

Trex Hideaway plastic clips, Hidfast™, CAMO™

screws/clips, and all non-TimberTech fasteners

should not be used with TimberTech PRO and

EDGE decking. These fasteners are known to

cause issues during or after deck installation,

including but not limited to gapping, warping,

board movement, oil canning, squeaking, corro-

sion, breaking/snapping of fasteners and uneven

deck surfaces. The AZEK Company will not be

financially liable in the event such issues arise.

Damaged products will not be covered under

warranty.

Fastener Mushrooming:

This may occur when a non-composite deck screw is

driven into the decking. It can be greatly reduced or

eliminated by using a screw designed for composite

lumber. When installing TimberTech decking, using

TOPLoc reduces chance of mushrooming. If mushroom-

ing occurs, we recommend pre-dimpling the board by

drilling a hole slightly smaller in diameter than the screw

head and as deep as the screw head before driving the

screen.
