Use top quality, corrosion-resistant 16-penny ringed-shank or spiral-shank nails to attach redwood decking. Smooth-shanked nails are likely to result in nail popping if green lumber and/or wet pressure-treated joists are used. Deck screws are also quite popular. Use corrosion-resistant, self-tapping deck screws with bugle heads. They should be manufactured from hardened steel. Electro galvanizing and other methods of zinc coating rarely show the same degree of corrosion resistance as hot-dip galvanizing.
