Simpson White Painted Siding Nail in 8d x 2-1/2", Type 316 Stainless Steel is a premium-quality fastener engineered specifically for cedar, redwood, and cypress siding materials. The white painted finish allows nail heads to blend seamlessly with siding surfaces, while the annular-ring shank delivers superior holding power - keeping siding panels firmly secured even under seasonal wood movement and outdoor exposure. Built from Type 316 stainless steel, these nails resist corrosion in demanding coastal and high-moisture environments where lesser fasteners would fail.

Key Features

• Type 316 Stainless Steel material - provides superior corrosion resistance compared to standard stainless grades, making these nails well-suited for seaside applications, humid climates, and long-term outdoor wood siding projects
• White painted finish - helps nail heads blend with white and light-colored siding surfaces, reducing visible fastener contrast for a cleaner, more professional appearance
• Checkered head pattern - mimics natural wood texture so the head integrates visually with cedar, redwood, and cypress siding rather than standing out against it
• Annular-ring shank - dramatically increases withdrawal resistance compared to smooth-shank nails, keeping siding firmly attached through thermal expansion, contraction, and wind loads
• 13-gauge, 0.092" shank diameter with diamond point - slender profile and sharp point drive more easily through wood fibers with less splitting, protecting the integrity of premium siding materials
• Full round head at 5/32" diameter - provides a broad bearing surface that holds siding panels securely without pulling through the material under stress
• Made in the United States - domestic manufacturing supports consistent quality standards for a fastener trusted in professional exterior siding applications

Why This Product

• Engineered for premium wood species - cedar, redwood, and cypress contain natural oils and acids that can react with and corrode standard fasteners; Type 316 stainless steel withstands these chemically active woods as well as saltwater and coastal air, making this nail the right choice where corrosion is a real concern
• Disappears into the siding surface - the combination of a white painted head and a checkered texture pattern means the nail blends with both the color and grain of light siding, eliminating the need for touch-up paint on every fastener
• Holds longer than smooth-shank alternatives - the annular-ring shank mechanically locks into wood fibers, resisting the nail pullout and loosening that can occur over time with standard smooth nails in exterior siding
• Reduces splitting risk in valuable siding material - the slender 13-gauge profile and sharp diamond point minimize wood displacement as the nail drives, helping protect expensive cedar and redwood boards from cracking at the edges

Frequently Asked Questions

Why is Type 316 stainless steel recommended for wood siding applications?

Type 316 stainless steel offers enhanced resistance to corrosion compared to standard grades, making it especially effective in coastal environments and when fastening naturally acidic wood species like cedar, redwood, and cypress. The material stands up to saltwater exposure, humidity, and the natural oils found in these premium siding woods without degrading over time.

What makes the annular-ring shank better for siding than a smooth shank?

The annular-ring shank features ridges along its length that mechanically lock into wood fibers as the nail is driven. This significantly increases withdrawal resistance compared to smooth-shank nails, helping keep siding panels firmly in place as wood expands and contracts with seasonal temperature and moisture changes.

Will the white painted head require touch-up after installation?

The durable painted finish is designed to help the nail head blend visually with white and light-colored siding material right out of the box. Note that hammer caps are recommended when driving painted-head nails to help preserve the painted finish on the head during installation.

Is the 13-gauge slender profile appropriate for cedar and redwood siding boards?

Yes. The slender 13-gauge shank diameter of 0.092 in., combined with a diamond point, is intentionally designed to drive through cedar, redwood, and cypress siding with minimal wood displacement. This reduces the risk of splitting along the edges or face of premium siding boards during fastening.
