Simpson 6d x 2" Annular Ring Shank Roofing Nail in 304 Stainless Steel is a professional-grade fastener engineered for secure, long-lasting roofing installations where corrosion resistance and superior holding power are essential. Manufactured by Simpson and made in the United States, this 11-gauge stainless steel roofing nail delivers the withdrawal resistance and bearing surface needed to firmly anchor roofing materials to wood decks and sheathing - even in demanding outdoor and coastal environments.

Key Features

• Type 304 Stainless Steel construction - provides superior corrosion resistance compared to standard galvanized fasteners, making these nails well-suited for harsh outdoor conditions, high-humidity environments, and applications where long-term performance is critical.
• Annular ring shank design - the ringed profile dramatically increases withdrawal resistance, locking the nail into wood members and plywood roof decks to prevent loosening over time and reduce the risk of roofing material uplift.
• Full round, large flat head at 0.375" diameter - the generous bearing surface distributes holding force across a wider area of roofing material, helping prevent tear-through and ensuring a firm, stable connection.
• 11-gauge shank at 0.12" diameter - a heavy-gauge wire thickness that balances strength and driveability, giving installers a nail that drives cleanly without excessive splitting in roofing substrates.
• Diamond point tip - the sharp, precision-cut point penetrates roofing materials and wood decking efficiently, reducing drive force and minimizing material damage during installation.
• Smooth head pattern - the clean head face seats flush and consistently, providing a professional finish and reliable contact with roofing material surfaces.
• 6d penny size, 2" length - a standard roofing nail length suitable for fastening asphalt shingles, felt underlayment, and similar roofing products to standard roof decking.

Why This Product

• For roofing projects in coastal, wet, or chemically challenging environments, 304 stainless steel provides a meaningful upgrade in corrosion resistance over standard coated or galvanized nails - helping rooftop fasteners maintain their integrity over the life of the roof.
• The annular ring shank directly addresses one of the most common roofing fastener failures - nail withdrawal - by mechanically interlocking with wood fibers to hold roofing materials firmly in place even under wind uplift and thermal movement.
• The large flat head at 0.375" diameter reduces the chance of the nail pulling through softer roofing materials, making this nail a reliable choice when fastening shingles, underlayment, or similar sheet goods to plywood decks.
• Produced by Simpson - a recognized name in structural fasteners and connectors - this nail is built to consistent dimensional standards, giving installers confidence in performance and compatibility across roofing applications.

Frequently Asked Questions

What makes the annular ring shank better than a smooth shank roofing nail?

The annular ring shank features a series of rings along the shank that mechanically lock into wood fibers as the nail is driven. This dramatically increases withdrawal resistance compared to a smooth shank nail, meaning the nail is far less likely to pull back out over time due to wind uplift, thermal expansion and contraction, or normal roof movement. For roofing applications where holding power is critical, the ring shank design provides a significantly more secure attachment to wood members and plywood roof decks.

Is Type 304 stainless steel appropriate for use with pressure-treated lumber or in coastal environments?

Type 304 stainless steel offers superior corrosion resistance compared to standard zinc-coated or galvanized fasteners, making it a strong choice for high-humidity, outdoor, and salt-air environments. It is well-suited for coastal roofing applications and exposure to the elements. For specific pressure-treated lumber compatibility requirements, always refer to the lumber manufacturer's recommendations and applicable building codes for your region.

What types of roofing materials is this 6d x 2" nail designed for?

This 6d penny, 2"-long roofing nail is a standard size used for fastening asphalt shingles, roofing felt and underlayment, and similar roofing sheet goods to plywood or wood roof decking. The large flat head at 0.375" diameter provides extra bearing surface to prevent tear-through of softer roofing materials, and the 2" length provides solid penetration into standard roof decking thicknesses.

Where are these roofing nails manufactured?

These Simpson roofing nails are manufactured in the United States, as noted in the Specifications section above.
