Expert Verdict — Reviewed by the SuperArbor Pro Desk
Cortex is the fastening method to specify whenever exposed screw heads would spoil a trimboard installation; the plug-and-screw system hides the connection completely while keeping the joint serviceable. Match screw length to trim thickness, stepping up to 2-3/4 in. for thicker profiles, and budget one Setting Tool per crew since each bit handles about 350 fasteners. Order the 750 LF box for full-fascia work to minimize per-unit cost.
Wear eye protection when driving fasteners; keep hands clear of the setting tool while installing plugs.
