Simpson 6d 2" Wood Siding Nail in Type 304 Stainless Steel is engineered by Simpson Strong-Tie for secure, long-lasting fastening of wood siding panels. Built with a 13-gauge annular-ring shank and a checkered full round head, this nail delivers exceptional withdrawal resistance and a clean, wood-grain-blending appearance that makes it a go-to choice for exterior siding installations where holding power and corrosion resistance both matter. The diamond point allows for smoother driving, while the Type 304 stainless steel construction stands up to outdoor moisture and the elements - making these nails well-suited for residential and light commercial wood siding applications.

Key Features

• Type 304 Stainless Steel material - provides corrosion resistance for exterior and moisture-exposed siding installations, helping the fastener maintain structural integrity over time
• Annular-ring shank - increases withdrawal resistance compared to smooth-shank nails, securing siding boards firmly and reducing cupping or loosening over time
• Checkered full round head pattern - blends with wood grain, reduces glare from sunlight, and accepts surface finishes so nail heads remain unobtrusive after installation
• Diamond point tip - allows for easier, more accurate driving through wood siding panels, reducing splitting and installation effort
• 13-gauge, 0.092" shank diameter at 2" length - sized specifically for wood siding fastening, balancing holding power with the material thickness typical of siding panels
• 5/32" head diameter - provides adequate bearing surface for pull-through resistance, helping keep siding panels firmly seated against the substrate
• Made in the United States - produced domestically by Simpson Strong-Tie, a trusted name in structural fastening solutions

Why This Product

• The annular-ring shank actively fights withdrawal forces caused by seasonal wood movement and wind loading - a key reason this nail is preferred for wood siding over standard smooth-shank alternatives
• Type 304 stainless steel construction makes these nails a reliable choice for exterior applications where standard steel fasteners would be vulnerable to rust staining, corrosion, or premature failure
• The checkered head pattern is designed specifically for siding work - it grips surface finishes and paints rather than letting them peel away from a smooth head, keeping the finished appearance intact longer
• With approximately 245 nails per pound, these 6d fasteners are practical for siding projects of varying scale, and the 2" length suits the penetration depth needed for reliable attachment to typical wood siding panels

Frequently Asked Questions

Why is an annular-ring shank important for wood siding nails?

The annular-ring shank features ridges along its length that grip the surrounding wood fibers, significantly increasing withdrawal resistance compared to a smooth-shank nail. For wood siding, this means the nail is far more resistant to being pulled back out over time - even as the siding expands, contracts, and flexes with seasonal temperature and humidity changes. This directly reduces cupping and loosening of siding boards.

What is the difference between Type 304 and Type 316 stainless steel for siding nails?

These nails are made from Type 304 stainless steel, which provides strong corrosion resistance suitable for most exterior siding applications. Type 316 stainless steel offers superior resistance in highly corrosive environments such as seaside or coastal locations where salt air is a factor. For projects in those environments, a Type 316 option would be the preferred choice.

What does the checkered head pattern do on a siding nail?

The checker pattern on the full round head is engineered to blend visually with wood grain, reducing the nail head's visual prominence after installation. It also reduces glare from sunlight and, importantly, accepts surface finishes such as paint or stain - helping the finish adhere directly to the nail head rather than peeling away from a smooth surface.

Is the diamond point on these nails a functional feature or just a style choice?

The diamond point is a functional feature. It is designed to pierce wood fiber more cleanly and with less resistance than a blunt or standard point, making it easier to drive the nail accurately without deflection. This is especially useful when fastening wood siding panels where consistent, straight penetration is important for a clean, professional finish.
