Simpson Dark Brown Painted Siding Nail, 10d x 3", 304 Stainless Steel is a premium fastener engineered specifically for attaching cedar, redwood, and cypress siding materials. Crafted from Type 304 stainless steel with a dark brown painted finish, this nail is designed so the head blends seamlessly with wood siding surfaces - keeping the finished look clean and professional. The checkered head pattern mimics natural wood texture for an even less visible fastener profile, making these nails a go-to choice for exterior wood siding installations where appearance and holding strength both matter.

Key Features

• Type 304 Stainless Steel material - provides strong corrosion resistance for exterior siding applications exposed to moisture and weather over time
• Dark brown painted finish - head color blends with cedar, redwood, and cypress siding for a cleaner, less visible installation
• Checkered head pattern - mimics wood grain texture so the nail head visually integrates with siding surfaces rather than standing out
• Annular-ring shank - the ring geometry dramatically increases withdrawal resistance, keeping siding panels firmly anchored against wind load and seasonal wood movement
• Full round head, 7/32" diameter - provides solid bearing surface for secure fastener seating without overdriving into siding material
• 12 gauge, 0.113" shank diameter with diamond point - the slender profile and sharp point make driving easier and reduce the risk of splitting cedar or redwood boards
• 10d x 3" length - sizing suited for penetrating siding material and reaching structural sheathing beneath for a reliable, code-appropriate attachment
• Made in the United States - domestic manufacturing supports consistent quality control and reliable material specifications

Why This Product

• Engineered for wood siding specifically - the combination of the painted dark brown head, checkered pattern, and slender 12-gauge shank addresses the two biggest concerns in siding work: appearance and splitting risk, solving both in a single fastener
• Annular-ring shank holds where smooth-shank nails fail - ring shanks grip wood fibers along the entire embedded length, which is critical for vertical siding panels that experience repeated thermal expansion, contraction, and wind pressure
• 304 stainless steel resists corrosion without staining - plain steel and lower-grade fasteners can rust and bleed brown streaks down siding; stainless steel maintains integrity and prevents unsightly staining on cedar, redwood, and cypress
• Dark brown paint finish reduces touch-up work - because the head color is matched to common brown-toned siding materials, less time is spent painting over nail heads after installation

Frequently Asked Questions

What types of siding material are these nails designed for?

These painted siding nails are designed for cedar, redwood, and cypress siding material. The slender 12-gauge shank and diamond point help prevent splitting in these typically straight-grained but sometimes brittle wood species.

Why does the shank type matter for siding applications?

The annular-ring shank on these nails significantly increases withdrawal resistance compared to a smooth-shank nail. This means the fastener grips wood fibers along its entire embedded length, helping siding panels stay firmly in place through seasonal wood movement, wind pressure, and repeated thermal expansion and contraction.

Is Type 304 stainless steel appropriate for all outdoor siding projects?

Type 304 stainless steel provides strong corrosion resistance suitable for most outdoor siding applications with cedar, redwood, and cypress. For seaside or coastal applications where salt air is present, Type 316 stainless steel is recommended for superior corrosion resistance in those more aggressive environments.

Why do these nails have a checkered head pattern and dark brown painted finish?

The checkered head pattern is designed to mimic wood grain texture so the nail head blends visually with the siding surface rather than standing out. The dark brown painted finish further helps the head match common wood siding tones, reducing the need for touch-up painting after installation.
