Simpson 15 deg. Wire Coil Ring-Shank Roofing Nail 1-3/4 in. 11 Ga Type 316 SS Full Round Head 3600-Pk is a professional-grade collated roofing nail from Simpson that pairs the fastening efficiency of 15 deg. wire-coil collation with the long-term durability of Type 316 stainless steel - delivering fast driving performance and superior holding power in asphalt and synthetic slate roofing applications. The full round head, annular ring shank, and diamond point work together to ensure secure, reliable attachment to OSB or plywood roof decks, while compatibility with many major manufacturers' pneumatic roofing tools keeps installation moving at pace on any job site.

Key Features

• Annular ring shank - increases withdrawal resistance so the nail holds firmly in OSB or plywood roof decks, reducing the risk of fastener pull-through over time
• Type 316 stainless steel material and finish - provides severe-level corrosion resistance, making these nails well suited for coastal, seaside, and other high-moisture roofing environments
• Full round head with smooth head pattern - distributes clamping force evenly across roofing material to minimize tearing and ensure a clean, professional result
• Diamond point tip - allows the nail to start and penetrate quickly, reducing driving force and operator fatigue during high-volume roofing work
• 15 deg. wire-coil collation - compatible with many major manufacturers' pneumatic roofing tools, helping reduce driving force and increase installation speed on the job site
• Ideal for asphalt and synthetic slate roofing - purpose-built for these application types so buyers can select with confidence for their specific roofing project

Why This Product

• Severe-level corrosion protection built in - Type 316 stainless steel goes beyond standard corrosion resistance, making these ring-shank roofing nails a dependable long-term fastener choice in demanding or coastal environments where ordinary nails can fail prematurely
• Engineered for speed without sacrificing holding power - the 15 deg. wire-coil collation speeds up pneumatic installation while the annular ring shank ensures each nail grips the roof deck firmly, combining jobsite efficiency with structural reliability
• A trusted name in structural fasteners - Simpson brings the same engineering focus found across its connector and fastener product lines to these collated roofing nails, giving roofing professionals a fastener backed by a recognized industry brand
• Made in the United States - domestic production supports consistent quality standards, which matters on commercial and residential roofing projects where fastener performance is critical to the finished installation

Frequently Asked Questions

What type of roofing is this nail designed for?

This nail is ideal for asphalt and synthetic slate roofing applications, as well as tile and slate roofing. Its annular ring shank provides superior holding power when fastening to OSB or plywood roof decks.

Why choose Type 316 stainless steel for roofing nails?

Type 316 stainless steel provides severe-level corrosion resistance, making it an excellent choice for roofing applications where exposure to moisture, salt air, or other corrosive elements is a concern - including seaside and coastal environments.

What is the collation angle and why does it matter?

These nails feature a 15 deg. wire-coil collation. This design is compatible with many major manufacturers' pneumatic roofing tools and helps reduce driving force while increasing installation speed, improving overall jobsite efficiency.

How does the annular ring shank benefit this roofing nail?

The annular ring-shank increases withdrawal resistance compared to smooth-shank nails, providing a more secure attachment when fastening roofing materials to OSB or plywood roof decks. This added holding power contributes to a longer-lasting, more reliable roof installation.
