Simpson 8d x 2-1/2" Dark Brown Painted Siding Nail in Type 304 Stainless Steel is a premium-quality fastener engineered specifically for cedar, redwood, and cypress siding applications. Built from corrosion-resistant 304 stainless steel with an annular-ring shank for maximum holding power, this dark brown painted nail is designed to blend seamlessly with wood siding while delivering a secure, long-lasting attachment. The checkered head pattern mimics natural wood grain texture, making these nails a trusted choice for exterior wood siding projects where both performance and a clean finished appearance matter.

Key Features

• Type 304 Stainless Steel construction - provides strong corrosion resistance, making these nails well-suited for outdoor siding environments and extended exposure to moisture and weather.
• Dark brown painted finish on the head - helps the nail head blend with cedar, redwood, and cypress siding so fasteners stay visually discreet after installation.
• Checkered head pattern - mimics natural wood grain texture so the nail head disappears into the siding surface rather than standing out.
• Annular-ring shank - dramatically increases withdrawal resistance compared to smooth-shank nails, holding siding boards firmly in place through seasonal wood movement and weather cycles.
• Slender 13-gauge, 0.092" shank diameter with a diamond point - allows easier driving with less splitting risk, protecting the integrity of your cedar, redwood, or cypress boards.
• Full round head at 5/32" diameter - distributes clamping load across the siding face for a secure, flush finish without over-sinking.
• 2-1/2" length (8d penny size) - sized appropriately to penetrate through typical wood siding panels and into structural framing for a code-ready fastening.
• Made in the United States - manufactured domestically to consistent quality standards for reliable, repeatable performance on every job.

Why This Product

• Engineered for wood siding aesthetics: The combination of a dark brown painted finish and a checkered head pattern means nail heads visually blend with cedar, redwood, and cypress siding - eliminating the contrast of bare metal on a finished exterior wall.
• Holds siding through seasonal movement: The annular-ring shank grips the surrounding wood fibers tightly, resisting the pull-through and loosening that can occur as wood siding expands and contracts with temperature and humidity changes.
• Reduces splitting risk in premium wood species: The slender 13-gauge shank paired with a sharp diamond point lets the nail displace wood fibers cleanly - important when working with valuable cedar, redwood, or cypress that can crack under heavier fasteners.
• Stainless steel protects against staining: Type 304 stainless steel does not bleed rust streaks onto siding the way carbon steel or lower-grade coated nails can, keeping the exterior finish looking clean over time.

Frequently Asked Questions

What wood siding species are these nails designed for?

These painted siding nails are designed specifically for cedar, redwood, and cypress siding materials - three species commonly used in exterior applications where a clean, blended fastener appearance is important.

Why does the shank type matter for siding applications?

The annular-ring shank increases withdrawal resistance compared to a smooth shank. This means the nail holds more firmly in the surrounding wood, resisting loosening caused by seasonal expansion and contraction of wood siding boards over time.

Will Type 304 stainless steel work in coastal or saltwater environments?

Type 304 stainless steel offers good general corrosion resistance for most outdoor siding applications. For seaside or high-salt-exposure environments, Type 316 stainless steel is typically recommended for superior corrosion resistance in those more demanding conditions.

What does the checkered head pattern do?

The checkered head pattern is designed to blend with natural wood grain texture on siding surfaces. Combined with the dark brown painted finish, it helps the nail head visually disappear into the siding material rather than contrasting against the wood face.
