Simpson 8d x 2-1/2" Sienna Painted Siding Nail in Type 304 Stainless Steel is a premium fastener engineered specifically for wood siding applications, including cedar, redwood, and cypress. The Sienna painted finish allows nail heads to blend seamlessly into siding material, while the checkered head pattern mimics natural wood texture for a clean, low-profile appearance. Built from Type 304 stainless steel with an annular-ring shank, this siding nail delivers lasting hold and corrosion resistance in exterior environments.

Key Features

• Type 304 Stainless Steel construction - provides reliable corrosion resistance for exterior siding installations exposed to moisture and weather
• Sienna painted finish - nail heads blend with siding material color so fasteners stay discreet and visually consistent on finished surfaces
• Checkered full round head pattern - mimics wood texture so the head integrates naturally with cedar, redwood, and cypress siding grain
• Annular-ring shank design - increases withdrawal resistance compared to smooth-shank nails, keeping siding panels firmly secured over time
• Slender 13-gauge body with diamond point - reduces splitting risk in wood siding and makes driving easier, even in dense materials like cedar
• 8d penny size at 2-1/2" length - the standard siding nail length that provides adequate penetration into framing while anchoring siding panels effectively
• Made in the United States - manufactured domestically to consistent quality standards

Why This Product

• Designed to disappear on your siding - the combination of Sienna paint and the checkered head pattern means nail heads blend with wood texture rather than standing out as an eyesore on finished cedar, redwood, or cypress installations
• Holds stronger than smooth-shank alternatives - the annular-ring shank bites into wood fibers for superior withdrawal resistance, reducing the risk of siding panels loosening or pulling away from the structure over time
• Right material for exterior wood siding - Type 304 stainless steel stands up to outdoor conditions, making this nail a dependable choice for wood siding exposed to humidity and wet environments
• Reduces splitting in fine siding materials - the slender 13-gauge profile and diamond point allow clean penetration into cedar, redwood, and cypress without cracking or damaging the siding material

Frequently Asked Questions

What types of wood siding are these nails designed for?

These painted siding nails are designed for cedar, redwood, and cypress siding materials. The slender 13-gauge body and diamond point help minimize splitting in these wood species, while the annular-ring shank provides a secure hold in the siding panels.

Why does the Sienna painted finish matter for siding installations?

The durable Sienna painted finish is applied specifically so that nail heads blend with siding material color on the finished surface. Combined with the checkered head pattern that mimics wood texture, these nails are far less visible than standard bright or galvanized fasteners once driven into place.

What is the benefit of an annular-ring shank over a smooth shank?

An annular-ring shank features ridges along the nail shaft that grip wood fibers and significantly increase withdrawal resistance. This means siding panels are held more securely over time compared to smooth-shank nails, which can loosen as wood expands and contracts with seasonal moisture changes.

Should I use Type 304 or Type 316 stainless steel for my siding project?

Type 304 stainless steel provides solid corrosion resistance suitable for most exterior siding applications. For projects in seaside or coastal environments where exposure to salt air is a concern, Type 316 stainless steel offers superior corrosion resistance and is the recommended choice for those conditions.
