Simpson 6d 2" Wood Siding Nail in Type 316 Stainless Steel is engineered by Simpson Strong-Tie for secure, long-lasting attachment of wood siding panels in demanding exterior environments. Featuring an annular ring shank for superior withdrawal resistance and a checkered full round head that blends naturally with wood grain, this nail is built to deliver powerful holding power and pull-through resistance where it counts most. Type 316 stainless steel construction makes it the right choice for coastal, seaside, and high-moisture applications where standard fasteners would quickly corrode and fail.

Key Features

• Annular ring shank - increases withdrawal resistance so siding boards stay firmly anchored, reducing cupping, warping, and loosening over time.
• Checkered full round head pattern - blends with natural wood grain, reduces glare from sunlight, and accepts surface finishes for a clean, low-profile appearance on finished siding installations.
• Type 316 stainless steel material and finish - provides superior corrosion resistance against saltwater, moisture, and harsh outdoor elements, making it well suited for seaside and coastal wood siding projects.
• Diamond point tip - drives more easily into wood siding panels, reducing splitting risk and installer fatigue during high-volume fastening work.
• 13-gauge shank (0.092 in. diameter) - offers a strong, slim profile that holds securely without over-splitting thin siding materials.
• 2" length / 6d penny size - sized appropriately for standard wood siding panel attachment, providing adequate penetration depth for reliable pull-through resistance.
• Made in the United States - manufactured domestically to consistent quality standards you can rely on for exterior construction applications.

Why This Product

• For wood siding in coastal or high-humidity environments, Type 316 stainless steel is the professional's choice - it withstands saltwater exposure and corrosive outdoor conditions that would degrade lower-grade fasteners and compromise siding integrity over time.
• The annular ring shank directly addresses one of the most common siding problems - boards that loosen, cup, or pull away from the structure - by providing significantly greater withdrawal resistance than smooth-shank nails.
• The checkered head pattern is purpose-designed for visible wood siding applications, reducing glare and accepting stains or paints so fastener heads do not detract from the finished appearance of your exterior siding.
• At 245 nails per pound on average, this 2" 13-gauge nail delivers an efficient combination of size, gauge, and holding strength specifically matched to the demands of fastening wood siding panels.

Frequently Asked Questions

Why is Type 316 stainless steel recommended for wood siding nails?

Type 316 stainless steel offers superior corrosion resistance compared to standard steel or lower-grade stainless options. It is specifically recommended for seaside and coastal applications where exposure to saltwater, moisture, and outdoor elements is constant. Using Type 316 stainless steel fasteners helps ensure the siding attachment remains structurally sound and corrosion-free over the long term.

What does the annular ring shank do compared to a smooth-shank nail?

The annular ring shank features ridges along the shank that lock into the wood fiber as the nail is driven, increasing withdrawal resistance significantly over smooth-shank nails. This means the fastener is harder to pull out over time, which helps prevent siding boards from loosening, cupping, or separating from the structure - a critical performance feature for exterior wood siding applications.

What is the checkered head pattern designed for?

The checker pattern on the nail head serves three practical purposes: it blends with the natural grain of wood siding for a less visually intrusive appearance, it reduces glare from sunlight on exposed fastener heads, and it accepts surface finishes such as stain or paint so the nail heads can be finished to match or complement the siding material.

What nail size and gauge is this wood siding nail?

This nail is a 6d penny size at 2 inches in length, with a 13-gauge shank measuring 0.092 inches in diameter. It features a diamond point for easier driving and a full round head with a 5/32 inch diameter. The approximate count is 245 nails per pound.
