Simpson 2d x 1" Annular Ring Shank Roofing Nail in Type 316 Stainless Steel is a professional-grade fastener engineered for roofing applications that demand exceptional holding power and long-term corrosion resistance. Crafted by Simpson Strong-Tie and made in the United States, this roofing nail features a full round head and annular ring shank that work together to anchor roofing materials firmly to wood decking and structural substrates - even in the most demanding outdoor environments. Whether you are installing roofing felt, lightweight tiles, or similar roofing materials in coastal, marine, or chemically aggressive settings, this nail delivers the mechanical grip and material durability that professionals require.

Key Features

• Type 316 Stainless Steel construction - provides superior resistance to saltwater, moisture, and chemical exposure, making this nail an ideal choice for coastal, marine, and high-humidity roofing environments where standard fasteners would corrode prematurely.
• Annular ring shank design - the threaded rings along the shank dramatically increase withdrawal resistance compared to smooth-shank nails, locking the fastener into wood members and plywood roof decks for a secure, long-lasting attachment.
• Full round head with smooth head pattern - the broad, flat head provides maximum bearing surface against roofing materials, reducing the risk of pull-through and firmly securing membranes, felts, or thin tiles without damaging the surface.
• Diamond point tip - enables clean, efficient penetration into roofing substrates and wood decking, reducing splitting risk and allowing faster installation.
• Manufactured in the United States - consistent quality control and material standards you can rely on for code-sensitive roofing projects.

Why This Product

• Built for corrosive environments - Type 316 stainless steel contains molybdenum, giving it enhanced resistance to chlorides and harsh outdoor conditions. This makes it the right nail for oceanfront homes, poolside structures, and roofing applications where moisture and salt are persistent threats to fastener longevity.
• Maximized withdrawal resistance from day one - the annular ring shank is not just about initial holding power - it resists the natural expansion and contraction of wood over time, keeping roofing materials locked in place through seasonal temperature swings and wind uplift forces.
• Large bearing surface prevents pull-through - the 0.375" full round head distributes load across a wider area of roofing material, reducing the chance of fastener pull-through on felts, membranes, or thinner substrates where a small-headed nail would fail.
• 1" length optimized for roofing overlays and underlayments - at 1 inch long, this nail is well-suited for securing roofing felt, underlayment, and lightweight roofing components to roof decks without over-penetrating thin substrates.

Frequently Asked Questions

What makes Type 316 stainless steel different from other nail materials for roofing?

Type 316 stainless steel contains added molybdenum compared to standard stainless grades, which significantly improves its resistance to chlorides, saltwater, and industrial chemicals. For roofing applications in coastal, marine, or chemically aggressive environments, this translates to a fastener that maintains structural integrity and appearance over the long term without rust staining or corrosion-related failure.

Why does an annular ring shank outperform a smooth shank nail in roofing applications?

The annular rings along the shank create a mechanical interlock with wood fibers as the nail is driven, dramatically increasing withdrawal resistance compared to a smooth shank. This is especially important on roof decks where wind uplift forces and the natural movement of wood from moisture and temperature changes can gradually loosen smooth-shank fasteners over time.

What applications is this 1" roofing nail best suited for?

At 1 inch in length with a 2d penny size, this nail is well-matched for fastening roofing underlayment, roofing felt, and lightweight roofing membranes to plywood or wood roof decks. Its large 0.375" full round head provides the broad bearing surface needed to hold these materials securely without tearing through them.

Is this roofing nail made in the United States?

Yes. This Simpson roofing nail is manufactured in the United States, which ensures consistent material standards and quality control - an important consideration for roofing projects subject to building codes or specifications that require domestic-sourced fasteners.
