Simpson 6d Shake and Shingle Siding/Roofing Nail in Type 316 Stainless Steel is engineered for securing wood shakes and shingles in demanding exterior roofing and siding applications where long-term corrosion resistance is critical. Crafted by Simpson Strong-Tie, this 2-inch annular-ring shank nail delivers a powerful hold in coastal, marine, and high-moisture environments where lesser fasteners fail prematurely. The slender 0.113-inch shank and diamond point work together to drive smoothly through shake and shingle materials without causing splits, while the 7/32-inch full round checkered head provides the bearing surface needed to keep shingles firmly in place through years of weather exposure.

Key Features

• Type 316 Stainless Steel material - delivers superior resistance to saltwater, chlorides, and harsh outdoor environments, making these nails ideal for coastal roofing and siding projects where corrosion is a constant concern.
• Annular-ring shank - increases withdrawal resistance significantly compared to smooth-shank nails, creating a more secure attachment that resists the natural movement and uplift forces shingles experience over time.
• 0.113-inch slender shank diameter - minimizes wood splitting during installation, protecting the integrity of cedar, wood, and other shake or shingle materials that are prone to cracking.
• Diamond point tip - allows for easier driving through dense shake and shingle materials, reducing installation effort and the likelihood of deflection during fastening.
• 7/32-inch full round head with checkered pattern - provides ample bearing surface to hold shingles securely, while the checkered texture blends with wood grain, reduces glare from sunlight, and accepts surface finishes for a cleaner finished appearance.
• 12-gauge wire diameter - balances strength and slenderness so the nail is robust enough for long-term structural holding without being so thick it damages the shingle material.
• Made in the United States - manufactured to consistent quality standards that roofing and siding professionals depend on for critical exterior fastening applications.

Why This Product

• Built for coastal and marine roofing applications - Type 316 stainless steel is the preferred alloy for salt-air and high-humidity environments, offering a level of corrosion resistance that standard galvanized or Type 304 stainless nails cannot match in the most aggressive outdoor conditions.
• Reduces callbacks from nail bleed and staining - stainless steel fasteners do not rust through the shingle face the way lesser finishes do, helping preserve the appearance and longevity of shake and shingle installations over the long term.
• Annular-ring shank adds holding power where wind uplift matters most - the ringed shank grips the substrate more aggressively than smooth-shank alternatives, offering enhanced withdrawal resistance in roofing applications where shingles are exposed to uplift loads.
• Designed specifically for shake and shingle work - every dimension, from the slender 0.113-inch shank that resists splitting to the wide 7/32-inch checkered head that distributes load across the shingle face, is optimized for this application rather than being a general-purpose nail pressed into service.

Frequently Asked Questions

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

Type 316 stainless steel contains molybdenum, which gives it superior resistance to chlorides, salt air, and harsh moisture compared to standard stainless alloys. For exterior roofing and siding applications - especially in coastal or marine environments - this alloy helps prevent the corrosion and staining that can compromise both the fastener's holding power and the appearance of the finished installation.

What is the benefit of an annular-ring shank on a shingle nail?

The annular-ring shank features circular rings along the shank that lock into the substrate as the nail is driven, dramatically increasing withdrawal resistance compared to a smooth-shank nail. In roofing applications where shingles can be subjected to wind uplift and thermal movement, this added holding power helps keep the shingle securely fastened over the life of the roof.

Why does the shank diameter matter when nailing wood shakes and shingles?

Wood shakes and shingles are prone to splitting if a nail shank is too thick relative to the material. This nail uses a slender 0.113-inch shank diameter - sized to provide structural holding strength while reducing the wedging force that causes cracks and splits during installation, which is especially important near the edges of individual shakes or shingles.

What does the checkered head pattern on this nail do?

The checkered pattern on the 7/32-inch full round head serves three practical purposes: it visually blends with wood grain for a less obtrusive appearance, it reduces glare from sunlight that can be caused by smooth, reflective nail heads, and it accepts surface finishes if the nailed surface is later painted or stained.
