Simpson 8d x 2-1/2" Redwood Painted Siding Nail in 304 Stainless Steel is a premium-quality fastener engineered specifically for cedar, redwood, and cypress siding installations. Made from Type 304 stainless steel, this nail delivers long-lasting corrosion resistance suited to exterior wood siding applications. The redwood-painted full round head blends seamlessly with siding surfaces, while the checkered head pattern mimics wood grain texture for a clean, low-visibility finish. Whether you are nailing cedar lap siding, redwood bevel boards, or cypress panels, this fastener is purpose-built to hold firmly and stay hidden.

Key Features

• Type 304 Stainless Steel material - provides strong corrosion resistance for exterior siding applications where moisture and weather exposure are ongoing concerns
• Redwood painted finish on the head - helps nail heads blend naturally with redwood siding material, minimizing visual disruption on finished surfaces
• Checkered head pattern - mimics wood grain texture so the head integrates visually with cedar, redwood, and cypress siding rather than standing out as a metal fastener
• Annular-ring shank - increases withdrawal resistance compared to smooth shank nails, providing a more secure and lasting attachment of wood siding panels
• Slender 13-gauge shank at 0.092 in. diameter - reduces splitting risk when driving into siding material, making installation cleaner and more reliable
• Diamond point tip - pierces wood fibers efficiently for easier driving with less force, reducing installer fatigue during high-volume siding jobs
• Full round head at 5/32 in. diameter - provides solid bearing surface against siding panels to hold them firmly in place without over-penetrating
• 8d penny size, 2-1/2 in. length - a standard sizing widely used for wood siding fastening, compatible with typical siding thicknesses and framing depths
• Made in the United States - domestically manufactured to consistent quality standards

Why This Product

• Designed specifically for cedar, redwood, and cypress siding - rather than a general-purpose nail, this fastener is purpose-built for these siding species, with the painted color and head pattern matched to blend with the natural appearance of these materials
• The annular-ring shank solves the siding pull-through problem - smooth shank nails can back out over time as wood expands and contracts seasonally; the ring shank design grips the wood fibers to resist withdrawal and maintain a lasting hold
• The painted redwood head keeps finished siding looking clean - for projects where fastener visibility matters, the color-matched head reduces the appearance of nail heads against redwood-toned siding surfaces
• Type 304 stainless steel is appropriate for non-marine exterior siding environments - offering corrosion resistance suitable for standard outdoor conditions without the premium cost of 316 stainless, making it a practical choice for inland and non-coastal siding projects

Frequently Asked Questions

What types of siding material is this nail designed for?

This painted siding nail is designed for cedar, redwood, and cypress siding material. The redwood painted head and checkered pattern are specifically intended to blend with these species' natural color and texture.

Why is an annular-ring shank used instead of a smooth shank for siding nails?

The annular-ring shank increases withdrawal resistance compared to smooth shank nails. This means the nail grips wood fibers more firmly and resists backing out over time as wood siding expands and contracts with seasonal moisture and temperature changes, providing a more secure and lasting attachment.

Is Type 304 stainless steel appropriate for coastal or seaside siding applications?

Type 304 stainless steel provides corrosion resistance suitable for standard outdoor and exterior siding environments. For seaside or salt-air applications where superior corrosion resistance is required, Type 316 stainless steel is the recommended choice. These nails are Type 304 stainless steel.

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

Yes, hammer caps are recommended when driving painted-head nails. Using a hammer cap helps protect the painted finish on the nail head during installation, preserving the color-matched appearance that allows the head to blend with the siding surface.
