Simpson 10d x 3" Redwood Painted Siding Nail in 304 Stainless Steel is a premium-quality fastener engineered by Simpson for use with cedar, redwood, and cypress siding material. Crafted from Type 304 stainless steel, this painted siding nail delivers lasting corrosion resistance in exterior wood siding applications. The redwood-painted head blends seamlessly with siding surfaces, making it a go-to choice for professional contractors and DIYers who demand a clean, finished look when fastening wood siding. With its annular-ring shank, diamond point, and checkered head pattern, this nail combines secure holding power with easy driving and a low-profile appearance.

Key Features

• Type 304 Stainless Steel material - provides strong corrosion resistance for outdoor and exposed siding applications, helping fasteners hold up in wet and humid environments without rusting through.
• Redwood painted finish on the head - blends with redwood, cedar, and cypress siding tones so nail heads are far less visible after installation, preserving the aesthetic of the finished surface.
• Checkered (checker pattern) head design - the textured head pattern mimics wood grain, further helping the nail head blend with the surrounding siding material for a discreet appearance.
• Annular-ring shank - the ring-shank profile dramatically increases withdrawal resistance compared to smooth-shank nails, keeping siding boards securely fastened even under seasonal wood movement and wind loading.
• Diamond point tip - the sharp diamond point allows the nail to start and drive more easily into dense cedar, redwood, or cypress siding, reducing splitting risk and speeding up installation.
• Full round head, 7/32" diameter - provides a broad bearing surface to seat firmly against siding material without over-driving or pulling through, ensuring a solid mechanical connection.
• 12-gauge, 0.113" shank diameter - the slender gauge threads through siding boards cleanly, minimizing wood splitting while still delivering the holding strength needed for exterior cladding.
• 10d penny size, 3" length - sized to penetrate through typical siding thicknesses and reach adequate embedment depth into framing for a code-appropriate, structurally sound attachment.
• Made in the United States - domestic manufacturing supports consistent quality control and material traceability for professional-grade fastening work.

Why This Product

• Designed specifically for cedar, redwood, and cypress siding - unlike general-purpose nails, this fastener is purpose-built for these wood species, with a painted redwood head color and checkered pattern that disappears into the siding surface rather than standing out.
• Annular-ring shank holds tighter over time - wood siding expands and contracts with seasonal moisture changes; the ring shank resists withdrawal forces that would cause a smooth-shank nail to work loose, reducing callbacks and long-term maintenance issues.
• 304 stainless steel protects against corrosion in outdoor exposures - exterior siding faces constant moisture, rain, and temperature swings; stainless steel construction resists rust staining that can bleed through painted or natural wood finishes and compromise appearance.
• Slender 12-gauge profile with diamond point reduces splitting risk - thinner nails with sharp points are less likely to split the narrow boards common in cedar and redwood siding profiles, helping installers work faster with fewer wasted materials.

Frequently Asked Questions

What wood siding materials is this nail designed for?

This painted siding nail is designed for use with cedar, redwood, and cypress siding material. The redwood-painted head and checkered pattern are specifically chosen to blend with the natural tones and texture of these wood species.

Why does this nail have an annular-ring shank instead of a smooth shank?

The annular-ring shank provides significantly greater withdrawal resistance than a smooth-shank nail. This means the nail holds more securely against the forces of wind, seasonal wood movement, and long-term outdoor exposure - keeping siding boards firmly attached over the life of the installation.

Is Type 304 stainless steel suitable for all exterior siding installations?

Type 304 stainless steel offers strong corrosion resistance for most exterior siding applications. For seaside or coastal environments with heavy saltwater exposure, Type 316 stainless steel is recommended for superior corrosion resistance in those more aggressive conditions.

Are hammer caps recommended when using these painted-head nails?

Yes - hammer caps are recommended when driving painted-head nails. This helps protect the painted finish on the nail head during installation so the head continues to blend with the siding surface after the nail is fully driven.
