The Simpson Strong-Tie S6SND1 Ring-Shank Wood Siding Nail is a Type 304 stainless steel exterior fastening nail built for attaching wood siding. This is a wood siding nail designed for fastening wood siding. Model Number S6SND1. In this version, you are getting a 2 inch long, 13 gauge nail with a 0.092 inch shank diameter and approximately 245 nails per 1 lb. package.

What matters here is how the design works in real use. The annular-ring shank gives the nail more withdrawal resistance than a smooth shank, which helps keep siding boards tight after seasonal movement, weather exposure, and normal expansion and contraction. If you are trying to avoid loose boards, lifted edges, or siding that starts to cup over time, that extra grip is the point of buying this style of nail.

The head and point details are also there for a reason. The full round head gives you broad bearing on the siding surface, while the checker pattern on the head helps it blend into wood grain better than a plain shiny head. It also reduces glare from sunlight and accepts surface finishes. The diamond point is made for easier driving, which matters when you are hand-driving nails into siding and want the nail to start cleanly without wandering.

For exterior work, material choice is a big deal. This S6SND1 version is made from Type 304 stainless steel, giving it solid corrosion resistance for wood siding applications where standard bright or lower-grade fasteners would not be the right call. Simpson Strong-Tie also offers some siding nails in Type 316 stainless steel for harsher seaside conditions, but this specific model is the 304 stainless version.

The sizing is straightforward and useful. At 2 inches long with a 5/32 inch head diameter, this nail fits the kind of siding fastening work where you need holding power without jumping to a larger, heavier nail. The 13 gauge body strikes a practical balance between penetration and grip, and the approximate count of 245 nails per pound gives you a realistic idea of coverage for repair work, smaller siding jobs, punch-list work, or targeted replacement.

If you are replacing cedar clapboards, fastening new wood siding, or handling exterior repair where corrosion resistance and holding power both matter, this is the kind of nail that makes sense. It is best suited to carpenters, remodelers, builders, and serious homeowners doing siding repair who want the right fastener instead of forcing a general-purpose nail into an exterior application.
