Simpson Premium Siding Nail - 6d, 2" x 7/32" Head, 316 Stainless Steel, 14 Gauge, Annular-Ring Shank by Simpson Strong-Tie is engineered for wood siding applications in severely corrosive environments where standard fasteners fall short. Crafted from passivated Type 316 stainless steel with an annular-ring shank, this nail delivers exceptional holding power and long-term corrosion resistance - making it the right choice for coastal, seaside, and other harsh exterior conditions where moisture, salt air, and chemical exposure are ongoing concerns.

Key Features

• Passivated Type 316 Stainless Steel material - delivers superior resistance to saltwater, chlorides, and severe outdoor environments, well beyond what standard stainless or galvanized nails can offer in coastal applications
• Annular-ring shank design - the ringed shank bites into wood fibers for dramatically increased withdrawal resistance and greater long-term holding power compared to smooth-shank nails
• Full round circle-pattern head (7/32" diameter) - the textured circle head reduces glare and readily accepts paint or surface finishes, leaving a clean, professional look on finished siding
• Diamond point tip - drives straight and true while minimizing the risk of splitting wood siding boards during installation
• 14-gauge wire diameter (0.083" shank) - provides the structural strength needed for secure siding fastening without being so heavy that it damages delicate siding materials
• 6d penny size at 2" length - the standard siding nail length for properly penetrating siding and reaching structural sheathing or framing beneath
• Made in the United States - manufactured domestically to consistent quality standards

Why This Product

• Purpose-built for severely corrosive conditions: Type 316 stainless steel is specifically formulated to resist saltwater and chloride attack, making these nails the appropriate choice when siding is exposed to seaside spray, marine air, or chemically aggressive environments where lesser fasteners would corrode and stain or fail prematurely.
• Passivation adds an extra layer of protection: Beyond the alloy itself, the passivation treatment enhances the stainless steel's natural oxide layer, further improving corrosion resistance so the nail maintains its integrity and appearance over the full life of the siding.
• The annular-ring shank prevents siding from backing out: Wood siding expands and contracts with seasonal moisture changes. The ringed shank mechanically locks into wood to resist the withdrawal forces that cause smooth-shank nails to creep loose over time - keeping siding tight and reducing callbacks.
• A complete siding nail engineered for exterior performance: Every feature - material, shank type, head pattern, point geometry, and gauge - is selected specifically for fastening wood siding, so installers get a fastener that performs reliably in real-world exterior conditions rather than a general-purpose nail pressed into service.

Frequently Asked Questions

Why is Type 316 stainless steel recommended for seaside or coastal siding applications?

Type 316 stainless steel contains molybdenum, which gives it elevated resistance to chloride attack - the primary cause of corrosion in saltwater and marine environments. Combined with passivation treatment that strengthens the alloy's protective oxide layer, these nails are specifically suited for siding in severely corrosive conditions where standard fasteners would rust, stain, or structurally degrade over time.

What advantage does an annular-ring shank provide over a smooth-shank nail for siding?

The annular-ring shank features a series of rings along the shank that mechanically interlock with wood fibers after the nail is driven. This significantly increases withdrawal resistance - meaning the nail resists being pulled back out as wood expands and contracts with seasonal moisture changes. For siding applications, this translates to fasteners that stay tight and siding that remains firmly secured over the long term.

Will the circle-pattern head accept paint or other surface finishes?

Yes. The circle head pattern is specifically designed to reduce glare and accept surface finishes. This allows paint, stain, or other coatings applied over the siding to adhere to the nail head, helping the fastener blend visually with the finished surface for a clean, professional appearance.

How does the diamond point help during installation?

The diamond point geometry is designed to drive straight and true, maintaining proper nail alignment as it penetrates wood siding. It also helps reduce board splitting during installation, which is especially important when working with wood siding where a cracked board from driving can mean wasted material and additional labor.
