Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match fastener length to the deck: enough embedment without protruding through the underside. Set torque on the screw gun so the head seats without stripping, and keep fasteners dry before installation.
Screw points are sharp; wear gloves and eye protection when handling and driving fasteners.
