Product Description
The Simpson S2SNDB Shake and Shingle Siding/Roofing Nail is a 2d, 1-inch fastener built for dependable performance in exterior roofing and siding installations. Crafted from Type 304 stainless steel, it delivers high-level corrosion resistance that keeps exterior assemblies secure and stable even in coastal, high-humidity, and weather-exposed environments. The 7/32 in. diameter full round head provides ample bearing surface to firmly hold all types of wood shakes and shingles, while the annular ring shank locks into substrate fibers to resist withdrawal over time. A slender 0.083 in. shank minimizes splitting during installation, and the diamond point allows for easier, more precise driving. The distinctive checkered head pattern blends naturally with wood grain, reduces glare from sunlight, and accepts surface finishes - making it a refined choice for visible exterior applications where aesthetics and performance both matter.
Key Features
- Type 304 stainless steel construction - provides high-level corrosion resistance, keeping fasteners structurally sound through years of moisture, humidity, and weather exposure without rusting or degrading.
- Annular ring shank - increases withdrawal resistance to lock the nail firmly in place, reducing the risk of shakes or shingles loosening over time due to wind, thermal cycling, or structural movement.
- Slender 0.083 in. shank diameter - minimizes splitting as the nail penetrates wood substrate, preserving the integrity of delicate shakes and shingles during installation.
- Diamond point tip - allows for easier driving and more accurate placement, reducing installer fatigue and improving efficiency on large roofing or siding projects.
- 7/32 in. full round head with checkered pattern - delivers ample bearing surface to secure all types of shakes and shingles, while the checker texture blends with wood grain, cuts down on sunlight glare, and accepts surface finishes for a cleaner finished appearance.
- 14-gauge wire - provides the structural strength needed to withstand the mechanical demands of exterior roofing and siding fastening without bending or deforming during installation.
- 25 lb. bulk packaging (approx. 530 nails per lb.) - supplies approximately 13,250 nails per box, making it a practical and cost-efficient choice for large-scale shake, shingle, or exterior cladding projects.
Why This Product
- Built for long-term exterior exposure - Type 304 stainless steel construction delivers high-level corrosion resistance, making these nails a reliable choice for roofing and siding projects in demanding environments where standard steel fasteners would rust and fail prematurely.
- Engineered to protect the material being fastened - the slender shank and diamond point work together to drive cleanly through wood shakes and shingles without splitting, preserving the structural and visual quality of the siding or roofing material itself.
- Holds stronger over time - the annular ring shank dramatically increases withdrawal resistance compared to smooth-shank alternatives, meaning fasteners stay locked in place through seasonal movement, wind loads, and long-term weathering.
- Finish-ready head design for professional results - the checkered full round head reduces glare and accepts surface finishes, making it well suited for applications where the nail head will remain visible and a clean, consistent appearance is part of the finished project standard.

Frequently Asked Questions
What type of stainless steel are these nails made from, and why does it matter for exterior use?
These nails are made from Type 304 stainless steel, which provides high-level corrosion resistance. This makes them well suited for exterior siding and roofing applications where exposure to moisture and the elements could cause standard steel fasteners to rust and degrade over time.
How many nails are included in a 25 lb. box?
Each 25 lb. box contains approximately 530 nails per pound, which works out to roughly 13,250 nails total - making it a practical bulk supply for large-scale roofing and siding projects.
What shank type do these nails have, and how does it benefit the installation?
These nails feature an annular ring shank, which increases withdrawal resistance to provide a more secure attachment compared to a smooth shank nail. The slender 0.083-inch shank diameter also helps minimize splitting in wood shakes and shingles during installation.
What is the head style on these nails, and is it suitable for visible wood applications?
These nails have a full round head with a 7/32-inch diameter that provides ample bearing surface to firmly secure shakes and shingles. The head features a checker pattern that blends naturally with wood grain, reduces glare from sunlight, and accepts surface finishes, making it a good choice for visible exterior wood applications.
