The Simpson 15 deg. Wire Coil Full Round Head Ring-Shank Framing Nail - 3-1/2 in. x.131 in., Type 316 Stainless Steel is engineered for general framing and wood deck board installations where holding power and long-term corrosion resistance are critical. Built by Simpson to meet demanding project requirements, this 16d, 10-gauge nail combines an annular ring shank with Type 316 stainless steel construction to deliver a secure, lasting attachment even in harsh, moisture-rich, or coastal environments. Wire-coil collation at 15 deg. keeps installation fast and efficient, and the nail is compatible with many major manufacturers' pneumatic coil nailers.

Key Features

• Type 316 stainless steel material and finish - provides severe-level corrosion resistance, making these nails a reliable choice for exterior, coastal, and high-moisture applications where standard fasteners deteriorate prematurely.
• Annular ring shank - increases withdrawal resistance compared to smooth-shank nails, locking into wood fibers for a stronger, more secure attachment that holds up under load and movement over time.
• Checkered head pattern - blends with wood grain, reduces glare from sunlight, and accepts surface finishes, resulting in a cleaner, less intrusive appearance on exposed deck boards and framing.
• Full round head - provides maximum bearing surface against the wood, distributing load evenly and reducing the risk of the head pulling through under stress.
• 15 deg. wire-coil collation - reduces driving force required during installation and increases nailing speed, helping crews work more efficiently on framing and decking projects.
• Diamond point tip - penetrates wood cleanly and consistently, minimizing splitting even in dense lumber commonly used in structural framing and deck construction.
• 1,800 nails per pack - supplies enough fasteners to sustain productivity on larger framing or multi-board decking jobs without frequent resupply interruptions.

Why This Product

• Built for severe corrosion environments - Type 316 stainless steel offers a higher level of corrosion resistance than Type 304 or standard galvanized fasteners, making these nails well suited for coastal construction, pressure-treated lumber applications, and other settings with persistent moisture exposure.
• Superior holding power for structural work - the annular ring shank mechanically locks into wood fibers to increase withdrawal resistance, which is especially important in deck board and framing connections that experience ongoing stress, seasonal movement, and loading.
• Broad pneumatic tool compatibility - the 15 deg. wire-coil format is accepted by many major coil nailer brands, giving crews flexibility to use the tools already on the job site without the need for specialized equipment.
• Finish-friendly head design - the checkered full round head reduces sunlight glare and accepts stains and surface finishes, so fastener heads remain inconspicuous on visible deck surfaces where aesthetics matter alongside performance.
