Product Description
Simpson 5d x 1-3/4 in. Annular Ring Shank Roof Nail with EPDM Washer, 304 Stainless Steel, 11 Gauge is a heavy-duty roofing fastener built for exterior sheathing and roofing panel applications where both holding strength and a watertight seal are required. Constructed from Type 304 stainless steel in 11-gauge wire, this nail pairs an annular ring shank with a full round head featuring a bonded EPDM sealing washer - backed by Type 316 stainless steel - to deliver corrosion-resistant performance and moisture protection at every fastener point.
Key Features
- Type 304 Stainless Steel Construction - Provides reliable corrosion resistance in exterior environments, keeping fasteners structurally sound over the long term in roofing and sheathing applications exposed to the elements.
- 11-Gauge Wire Diameter - A heavy-gauge shaft delivers consistent holding power across a range of substrate densities, reducing the risk of fastener failure under load.
- Annular Ring Shank - The threaded ring profile along the shank dramatically increases withdrawal resistance compared to smooth-shank nails, keeping roofing and sheathing panels firmly in place against wind uplift and thermal movement.
- Full Round Head with Bonded EPDM Washer - Creates a watertight seal around each fastener penetration point, helping prevent moisture intrusion from wind-driven rain or pooling water.
- Type 316 Stainless Steel Washer Backing - The EPDM washer is backed by Type 316 stainless steel, adding an extra layer of corrosion resistance right at the head-to-substrate interface where moisture exposure is highest.
- Diamond Point Tip - Promotes clean, accurate penetration into roofing substrates, reducing the chance of splitting or misalignment during installation.
- Made in the United States - Manufactured domestically to consistent quality standards for professional roofing and exterior sheathing work.
Why This Product
- A complete sealing solution in a single fastener - The combination of a bonded EPDM washer and a Type 316 stainless steel backer means each nail does double duty: securing the panel and sealing the penetration point against moisture intrusion, without requiring separate sealing steps.
- Engineered for long-term hold in demanding roofing conditions - The annular ring shank resists withdrawal forces caused by wind uplift and seasonal thermal movement, making this nail a dependable choice for exterior roof and wall sheathing that needs to stay put over time.
- Stainless steel construction throughout - With Type 304 stainless steel for the nail body and Type 316 stainless steel backing the washer, corrosion resistance is built into every component - not just the visible surface - for performance in moisture-prone exterior settings.
- A trusted Simpson fastener built to professional standards - Sourced from Simpson and made in the United States, this nail is designed to meet the demands of professional roofing and sheathing installations where fastener quality directly affects long-term weather resistance.

Frequently Asked Questions
What makes the annular ring shank on this nail better than a smooth-shank nail for roofing?
The annular ring shank features a threaded ring profile along the shaft that dramatically increases withdrawal resistance compared to smooth-shank nails. This means the nail resists being pulled back out of the substrate over time, keeping roofing and sheathing panels firmly secured even under stress from wind uplift or thermal movement.
What is the purpose of the EPDM washer, and what backs it?
The EPDM washer is bonded to the underside of the full round head and creates a watertight seal around the fastener penetration point, helping to prevent moisture intrusion. The washer is backed by a Type 316 stainless steel plate, which provides additional structural support and corrosion resistance at the seal interface.
Why is Type 304 stainless steel specified for this nail?
Type 304 stainless steel offers excellent corrosion resistance, making it well suited for long-term performance in exterior environments where the fastener is exposed to moisture, weather, and the elements. This material choice helps ensure the nail maintains its integrity over the life of the roofing installation.
Where is this nail manufactured?
This nail is manufactured in the United States.
