Simpson 6d 2" Shake and Shingle Siding/Roofing Nail in Type 304 Stainless Steel is engineered for secure, long-lasting fastening of wood shakes, shingles, and exterior siding. Built by Simpson Strong-Tie, these annular-ring shank nails deliver superior withdrawal resistance and corrosion protection, making them a reliable choice for roofing and wood siding applications where moisture exposure and long-term holding power matter most. The 7/32 in. full round head provides generous bearing surface, while the slender 13-gauge shank helps prevent wood splitting during installation.

Key Features

• Type 304 Stainless Steel material - provides strong corrosion resistance for exterior roofing and siding applications exposed to weather and moisture
• Annular-ring shank - increases withdrawal resistance compared to smooth-shank nails, keeping shakes and shingles firmly secured over time
• 7/32 in. full round head with checkered pattern - delivers ample bearing surface to hold shingles and siding in place, while the checkered texture blends with wood grain, reduces glare from sunlight, and accepts surface finishes
• Slender 13-gauge, 0.092 in. shank diameter - minimizes the risk of splitting wood shakes and shingles during driving
• Diamond point tip - allows for easier driving and cleaner penetration into wood siding and roofing materials
• 2 in. length / 6d penny size - sized appropriately for standard shake and shingle fastening tasks in both roofing and exterior siding installations
• Approximately 237 nails per pound - makes it straightforward to estimate quantities needed for a given project
• Made in the United States - domestically manufactured to consistent quality standards

Why This Product

• The Type 304 Stainless Steel construction resists rust and corrosion in demanding outdoor environments, helping wood shake and shingle installations maintain their integrity over many years without fastener failure.
• The annular-ring shank design actively fights nail pull-through and withdrawal - a critical advantage in roofing and siding applications where wind uplift and seasonal movement put constant stress on fasteners.
• The slender shank paired with a diamond point addresses one of the most common problems when nailing shakes and shingles - wood splitting - allowing clean, precise installation without damaging the material being fastened.
• The checkered full round head balances holding performance with a low-profile appearance, blending into wood surfaces and reducing visible glare, which is especially valuable on exposed exterior siding and roofing installations.

Frequently Asked Questions

What type of shank does this nail have, and why does it matter for roofing and siding?

This nail features an annular-ring shank, which increases withdrawal resistance compared to smooth-shank alternatives. For roofing and wood siding applications, this means the nail grips the substrate more securely and resists being pulled out by wind uplift, thermal expansion, and the natural movement of wood over time.

Is Type 304 Stainless Steel suitable for outdoor and weather-exposed applications?

Yes. Type 304 Stainless Steel offers strong corrosion resistance, making these nails well suited for exterior roofing and siding installations where fasteners are regularly exposed to moisture, rain, and outdoor conditions. The stainless steel construction helps prevent rust that could stain or compromise the surrounding wood material.

Why does this nail have a slender shank, and what gauge is it?

The shank is a 13-gauge design with a 0.092 in. diameter. The slender profile is intentional - it minimizes the displacement of wood fibers during driving, reducing the likelihood of splitting delicate shakes and shingles. This is particularly important when fastening thin or aged wood roofing and siding materials.

What is the significance of the checkered head pattern on this nail?

The checkered pattern on the 7/32 in. full round head serves several practical purposes. It helps the head blend visually with wood grain, reduces glare from direct sunlight on exposed exterior surfaces, and accepts surface finishes - making these nails a good fit for visible siding applications where aesthetics alongside holding performance are both considerations.
