Sheathing nail spacing should prioritize edge control and field fastening to keep plywood or oriented strand board secured under wind loads.

Use six inches on center at panel edges and twelve inches on center in the field as a practical thumb rule for standard conditions, and tighten to eight inches on center at edges or throughout the panel when you are in higher wind zones. Drive nails so the heads are flush with the sheathing surface without crushing the panel face and start nailing from the center outward to avoid panel oil can or buckling. For better withdrawal resistance on studs and rafters choose ring shank nails or screws designed for sheathing rather than smooth shank nails, and follow the fastener length guidance so the fastener penetrates at least one and one quarter inches into framing members. Stagger fastener rows near panel edges to reduce splitting in narrow studs and always keep a consistent pattern so the load path from the sheathing to the framing is continuous. Check the sheathing and fastener manufacturer instructions for any specific spacing adjustments or fastener types required for treated panels or for engineered panels that may call for closer spacing. When working in cold or wet conditions allow material to acclimate and avoid overdriving nails, and if you use power nailers check calibration frequently so every fastener is driven to the same depth.

People commonly underfasten by using wider spacing than panels or local conditions require, which leads to wind uplift failures; follow the six inch edge and twelve inch field rule or closer where required and verify with the panel maker. Overdriving or crushing heads reduces holding strength and can split face veneers or decking, so aim for flush heads and adjust nail gun pressure or use a hand tool for troublesome spots. Mistaking fastener type causes premature pull out under load, so use ring shank nails or structural screws for improved withdrawal resistance and always confirm length for one and one quarter inches minimum embedment into framing.
