Fasteners for Cedar Siding: What Kind of Nails and How to Use Them

Installation, Care, and Maintenance of Wood Shake and Shingle Siding gives handy advice to the homeowner who wants to install cedar siding.

Nail placement for cedar shingles up to 10 inches (254 mm) wide requires two corrosion-resistant nails driven 3/4 inches (19 mm) from each edge and 1 inch (25 mm) above the exposure line. For shingles wider than 10 inches (254 mm), drive two additional nails approximately 1 inch (25 mm) apart near the center.


Corrosion-resistant fasteners.

To decrease the chance of splitting the shake or shingle, fasteners should be blunted siding nails and should be ring- or twist-shank to improve holding. A ring-shank nail will have adequate holding power if it penetrates ¾ inch (19 mm) into the wood.

Corrosion-resistant nails are needed to avoid iron stains caused by extractives in the wood and corrosion by acid rain, salt air, etc. Certain preservative- and fire-retardant treatments also may be corrosive. Check with the product supplier for recommendations on proper fasteners for their products. Non-corrosive siding-nails are available in hot-dipped galvanized (as per ASTM A 153/D) Standard Specification for Zinc Coating (Hot-Dip) on Iron and Steel Hardware and type 304 or 316 stainless steel. Additional information may be available from supplier websites, and some suppliers may have additional requirements.
