Nail Sdg Wood 316Ss 1-3/4 1Lb 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 f illet 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. NOTE: Use 316 Stainless steel for seaside applications and superior corrosion resistance.
