The Simpson T5FN1 1-3/4" 5d Finishing Nail in Type 316 Stainless Steel delivers exceptional corrosion resistance and a clean, low-profile finish for demanding fastening applications. Manufactured to 14-gauge thickness with a smooth shank and diamond point, these finishing nails drive cleanly and precisely into a variety of materials. The brad head design sits only slightly larger than the shank, allowing the nail to be countersunk below the work surface and concealed with minimal effort - ideal wherever a discreet, polished result is required. Type 316 stainless steel provides superior protection against corrosion, making these nails an outstanding choice for seaside and other highly corrosive environments where long-term fastener integrity is essential.
