316 Stainless Steel Screws for TimberTech Cortex Installation
What Cortex Screws Are
The Cortex® Hidden Fastener System from TimberTech uses specialty deck screws paired with deck plugs (not included) that match your board material and color. After driving the screw from the top down, you insert a plug to hide the screw head, leaving a sleek, professional look.
TimberTech sells Cortex fasteners (screws + plugs) in kits sized by coverage and material type (PVC or composite).
