If you're working with cedar or redwood siding, these Simpson Strong Tie nails are exactly what you need for a professional, long-lasting installation! The 3-1/2 inch length and 14 gauge thickness provide plenty of holding power for siding applications. Made from 304 stainless steel, they're completely rust-resistant and won't stain your beautiful wood siding like regular steel nails can. The checker head pattern is designed to blend seamlessly with wood grain, so the fasteners are much less noticeable once installed. The annular ring shank is a game-changer - those rings along the nail shaft create incredible holding power that prevents nails from working loose over time as wood expands and contracts with weather changes. The diamond point makes driving them in much easier, whether you're using a hammer or nail gun. You get about 88 nails per pound, which is plenty for most siding projects. Simpson is a trusted name in construction fasteners, so you know these are quality nails that will perform exactly as expected. They're specifically engineered for cedar and redwood, which can be more sensitive to staining from certain metals. Whether you're a professional contractor or a DIY homeowner tackling a siding project, using the right nails makes all the difference in how your finished project looks and how long it lasts. These nails might cost a bit more than regular ones, but they're absolutely worth it for protecting your investment in beautiful wood siding!
