Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose 316 stainless for coastal projects, cedar and redwood, and for ACQ or CA treated lumber, where fastener corrosion is the first failure point. The 2-1/2 in. #10 size is the workhorse for face-fastened decking, while the 1-5/8 in. #7 suits thinner stock. Pre-drilling is usually unnecessary thanks to the Type 17 auger tip, but a test drive on the actual board is always wise.
Wear eye protection when driving screws, and handle bulk screw boxes carefully as sharp tips can scratch skin.
