What kind of fastener should I use with TimberTech?
For installing TimberTech solid planks, we recommend stainless steel or high-quality coated deck screws. For XLM Plank, Earthwood Plank, TwinFinish Plank and ValuPlank: use a minimum #8 x 2-1/2″. For DockSider Plank: use a minimum #8 x 3″. Refer to our Installation Resources for more information. TimberTech grooved planks are installed using the TimberTech CONCEALoc Hidden Fastener. Follow the directions on the CONCEALoc box or bucket.
