Wood Siding Nails 3D 0.083" x 1-1/4'' Stainless Steel 1 LB Simpson Strong S3SND1 The Simpson Strong-Tie S3SND1 is a premium 3D (1-1/4 inch) stainless steel siding nail engineered for superior holding power and long-term corrosion resistance in exterior wood siding applications. Featuring an annular ring shank, it delivers exceptional pull-out resistance to minimize board cupping and ensure secure, lasting attachment ? even under thermal expansion or high-wind conditions. The round head includes a subtle checker pattern that blends with natural wood grain, reduces sun glare, and readily accepts paint or stain for seamless finishing. Made from coated stainless steel with a diamond point for easier driving, these nails are ideal for both interior and exterior use. For coastal or high-salt environments, Type 316 stainless steel is recommended (sold separately), but this standard version offers robust performance in most residential and commercial siding projects. Each 1-pound box contains 495 nails ? enough for large-scale installations ? and is neatly packaged for jobsite organization and transport. With a shank diameter of 0.083 inches (14 gauge) and head diameter of 5/32 inches, these nails are optimized for use with wood siding, shiplap, bevel-back, or lap boards. Their rugged construction and thoughtful design make them a contractor-grade choice for builders and remodelers who demand durability, aesthetics, and code-compliant performance.
