Simpson Strong-Tie S8SND5 Siding Nail, 8d, 2-1/2 in L, 304 Stainless Steel, Full Round Head, Annular Ring Shank, 5 lb

Highest quality nails for cedar, redwood and cypress siding materials. High tensile nickel/chromium stainless steel will last the life of wood siding without degradation ever. Slender gauge and blunt diamond point minimize splitting. Generous under-head fillet allows nails to be driven flush or countersunk without crushing surrounding wood. Checker pattern head blends with wood texture and serves to diffract sunlight. Annular ring threads preclude cupping of siding boards and nail-head popping. Use 316 Stainless steel for seaside applications and excellent corrosion resistance.
