Simpson 6d 2" Shake and Shingle Siding/Roofing Nail in Type 316 Stainless Steel by Simpson Strong-Tie is engineered for secure, long-lasting attachment of wood shakes, shingles, and siding in demanding outdoor environments. Crafted from Type 316 stainless steel, these roofing nails deliver exceptional corrosion resistance, making them a reliable choice for coastal, marine, and high-moisture applications where standard fasteners may fail. The annular-ring shank and checkered full round head work together to create a firm, lasting hold in roofing and wood siding projects.

Key Features

• Type 316 Stainless Steel material - resists corrosion from saltwater, moisture, and harsh outdoor conditions, ensuring long-term fastener integrity in demanding environments
• Annular-ring shank - increases withdrawal resistance compared to smooth-shank nails, keeping shakes and shingles securely anchored even under repeated wind and thermal movement
• 7/32 in. full round head diameter - provides ample bearing surface to hold shakes and shingles firmly without pulling through the material
• Checkered head pattern - blends with wood grain texture, reduces glare from sunlight, and accepts surface finishes for a cleaner, more finished appearance
• Slender 0.092 in. shank diameter (13 gauge) - minimizes wood splitting during installation, protecting the integrity of delicate shakes and thin shingles
• Diamond point tip - penetrates wood more easily during driving, reducing installation effort and the risk of glancing or deflection
• Made in the United States - manufactured domestically to consistent quality standards

Why This Product

• For roofing and siding projects exposed to moisture, rain, or salt air, Type 316 stainless steel provides a significant advantage over standard galvanized nails by resisting rust and corrosion that can stain wood and compromise the fastener over time.
• The annular-ring shank design dramatically improves holding power compared to smooth-shank alternatives, meaning shakes and shingles stay fastened securely through seasonal expansion, contraction, and wind loading.
• The slender 13-gauge shank paired with a diamond point makes these nails well-suited for thin or fragile roofing materials where splitting is a common installation problem - reducing waste and rework.
• The checkered flat head blends aesthetically with natural wood surfaces and accommodates stains and finishes, making these nails appropriate for visible siding applications where appearance matters alongside performance.

Frequently Asked Questions

Why is Type 316 stainless steel used for shake and shingle nails?

Type 316 stainless steel offers superior corrosion resistance compared to standard steel or even Type 304 stainless, making it well-suited for roofing and exterior siding applications where fasteners are regularly exposed to moisture, humidity, and potentially salt air. Corrosion-resistant fasteners also prevent the rust staining that can discolor natural wood shakes and shingles over time.

What is the advantage of an annular-ring shank on a roofing nail?

An annular-ring shank features ridges along the shank that grip the surrounding wood fibers and significantly increase withdrawal resistance compared to a smooth-shank nail. This means the nail resists being pulled back out due to wind uplift, thermal cycling, or the natural movement of roofing and siding materials - providing a more secure and durable attachment.

Will the slender shank split my cedar shakes or thin shingles during installation?

The nail features a slender 0.092 in. (13-gauge) shank specifically designed to minimize splitting in delicate roofing materials like cedar shakes and shingles. Combined with the diamond point for cleaner wood penetration, these nails are engineered to reduce the risk of splitting that is common with thicker or blunter fasteners.

How many of these nails are in a pound?

There are approximately 237 nails per pound for this 6d, 2 in. Type 316 stainless steel shake and shingle nail. Refer to the Available Pack Options section to select the quantity that fits your project needs.
