Simpson 1-1/2 in. 15 deg. Wire Coil Ring-Shank Siding Nail 13 Ga Full Round Head Type 316 SS 1800-Pk is a professional-grade collated fastener from Simpson engineered for efficient, long-lasting siding installation. Built for use in fiber cement boards and compatible with many major manufacturers' pneumatic coil nailers, this 4d nail pairs the speed advantage of wire-coil collation with the long-term durability of Type 316 stainless steel - making it a dependable choice for coastal construction and any environment where corrosion resistance is critical.

Key Features

• Optimized for fiber cement board siding - purpose-built for one of the most demanding siding materials, reducing the risk of fastener failure or surface damage during installation.
• Checkered head pattern - blends with wood grain, reduces glare from sunlight, and accepts surface finishes, so fastener heads remain inconspicuous after installation.
• Generous underhead fillet - allows nails to be driven flush or countersunk without crushing the surrounding material, resulting in a cleaner, more professional finish.
• Annular ring shank - increases withdrawal resistance to provide a secure attachment that reduces cupping of siding boards over time, keeping the finished surface stable and flat.
• Slender 13-gauge body with diamond point - makes driving easier and cleaner, reducing splitting and installation effort whether working by hand or with a pneumatic tool.
• 15 deg. wire-coil collation - compatible with many major manufacturers' pneumatic coil nailers, cutting installation time and reducing driving force compared to hand-nailing.
• Type 316 stainless steel construction - delivers superior corrosion resistance in seaside and salt-air environments where standard fasteners degrade quickly, protecting the integrity of the siding system for years.

Why This Product

• Coastal-grade corrosion resistance built in - Type 316 stainless steel goes beyond standard stainless grades, making these nails a reliable fastener solution for seaside and high-moisture environments where fastener corrosion is a leading cause of siding failure.
• Speed and precision through pneumatic compatibility - the 15 deg. wire-coil format works with many major manufacturers' pneumatic tools, allowing installers to drive more fasteners in less time without sacrificing placement accuracy.
• Engineered to prevent siding movement - the annular ring shank actively resists withdrawal, holding siding boards firmly in place and reducing the cupping and warping that can develop with smooth-shank alternatives over time.
• Finish-friendly design for cleaner results - the checkered head and generous underhead fillet work together to minimize visible fastener impact, allowing heads to sit flush or slightly countersunk while accepting paint or other surface finishes seamlessly.

Frequently Asked Questions

What type of material are these siding nails made from, and why does it matter?

These nails are made from Type 316 stainless steel, which provides superior corrosion resistance compared to standard stainless steel grades. This makes them especially well-suited for seaside and coastal applications where exposure to salt air and moisture can rapidly degrade lesser fasteners.

Are these nails compatible with pneumatic coil nailers?

Yes. The T13A150SNJ is a 15 deg. wire-coil collated nail that is compatible with many major manufacturers' pneumatic tools, allowing for faster installation and reduced driving force compared to hand-nailing.

Why is an annular ring shank preferred for siding installation?

The annular ring shank increases withdrawal resistance, providing a more secure attachment than a smooth-shank nail. This helps reduce cupping of siding boards over time, maintaining a cleaner, more stable finished appearance.

How does the head design benefit the finished appearance of siding?

The full round head features a checker pattern that blends with wood grain, reduces glare from sunlight, and accepts surface finishes. Additionally, the generous underhead fillet allows nails to be driven flush or countersunk without crushing the surrounding wood, resulting in a cleaner, professional finish.
