Simpson 1 in. x 2d Finishing Nail in 316 Stainless Steel, 15 Gauge is a precision-crafted finishing nail built for applications where corrosion resistance and a clean, concealed finish matter most. Made by Simpson from Type 316 stainless steel, this 1 in. smooth-shank nail features a brad head that sits only slightly larger than the 0.072 in. shank diameter, allowing it to be countersunk below the work surface and hidden from view. Whether you are working near the coast, in high-moisture environments, or with materials that demand long-lasting fastener performance, this nail is engineered to hold up where standard steel fasteners fall short.

Key Features

• Type 316 stainless steel construction - delivers superior resistance to saltwater, moisture, and corrosive environments, making it ideal for seaside and outdoor applications where ordinary nails would rust and fail prematurely
• Brad head design (0.109 in. head diameter) - the head is only slightly larger than the shank, allowing the nail to be countersunk and concealed beneath the work surface for a clean, professional finish
• 15-gauge, 0.072 in. smooth shank - provides reliable holding power while remaining slim enough for delicate trim and finish work without splitting the material
• Diamond point tip - reduces driving resistance so the nail seats cleanly and accurately, minimizing the risk of surface damage during installation
• 1 in. length (2d penny size) - suited for thin trim, light molding, and finish applications where a shorter nail is needed without sacrificing secure fastening
• Smooth shank profile - enables consistent, controlled driving by hand or with a finish nailer, reducing installation effort on detailed millwork and trim
• Made in the United States - domestic manufacturing supports consistent quality control standards throughout production

Why This Product

• The right choice for coastal and marine environments - Type 316 stainless steel is specifically formulated for high-chloride, saltwater-exposed conditions where even galvanized fasteners can corrode over time, protecting both the nail and the surrounding material
• Invisible finish when properly installed - the brad head and narrow 0.072 in. shank mean this nail can be driven below the surface and filled over, leaving no visible fastener mark on trim, molding, or finish woodwork
• Fasteners that last as long as the materials they fasten - using stainless steel nails prevents the premature rust staining and structural weakening that can occur when lower-grade fasteners corrode inside quality materials
• Optimized for light finish applications - the 1 in. length and 15-gauge wire diameter hit the practical sweet spot for securing thin trim and detail work without over-penetrating or causing splits

Frequently Asked Questions

What makes Type 316 stainless steel different from standard stainless steel for nails?

Type 316 stainless steel contains molybdenum, which significantly improves its resistance to chlorides and saltwater compared to standard 304 stainless steel. This makes it the preferred choice for seaside, marine, and other highly corrosive environments where long-term fastener integrity is critical.

How do I conceal these finishing nails after installation?

The brad head on this nail has a diameter of just 0.109 in. - only slightly larger than the 0.072 in. shank. This small profile allows the nail to be countersunk below the work surface using a nail set, after which the recess can be filled with wood filler or putty and sanded flush for an invisible finish.

What applications are these 1 in. finishing nails best suited for?

At 1 in. in length (2d penny size) with a smooth 15-gauge shank and diamond point, these nails are well-suited for light trim work, thin moldings, delicate finish woodwork, and other applications where a short, fine nail is needed to secure material cleanly without splitting or over-penetrating.

How many nails are in a pound of these 15-gauge finishing nails?

There are approximately 863 nails per pound for this 1 in., 15-gauge, 2d finishing nail in Type 316 stainless steel. This count can help you estimate how much product you need based on the scale of your project.
