Simpson 5d x 1-3/4" Annular Ring Shank Box Nail in 316 Stainless Steel is a premium fastener engineered for demanding outdoor and coastal construction environments where ordinary nails fall short. Manufactured by Simpson, these box nails combine a corrosion-resistant 316 stainless steel composition with an annular ring shank profile to deliver a strong, lasting hold in applications exposed to moisture, salt air, and harsh weather. Whether used in seaside structures, decking, siding, or permanent wood foundations, these nails are designed to perform where durability and withdrawal resistance are critical.

Key Features

• Type 316 stainless steel construction - provides superior corrosion resistance compared to standard stainless grades, making these nails the right choice for seaside and salt-spray environments where long-term durability is essential.
• Annular ring shank design - dramatically increases withdrawal resistance over smooth-shank nails, creating a secure mechanical grip that holds tight even under repeated stress or wood movement cycles.
• Checkered head pattern - blends naturally with wood grain surfaces, reduces glare from direct sunlight, and readily accepts stains, paints, and other surface finishes for a clean, finished appearance.
• Full round head with diamond point - the broad head provides a wide bearing surface to prevent pull-through, while the diamond point enables easier driving and cleaner entry into wood fibers.
• 13 gauge, 0.092" shank diameter - the slender box-nail profile reduces splitting in thinner or harder wood stock while still delivering reliable holding strength.
• 1-3/4" length (5d penny size) - a versatile fastener length suited to a wide range of light framing, sheathing, and trim applications without over-penetrating thinner material assemblies.
• 3/16" head diameter - sized to bear across the nail surface efficiently, balancing a low-profile look with solid clamping force against the workpiece.

Why This Product

• Choosing 316 stainless steel over standard 304 stainless means significantly better resistance to chloride-rich environments - the right choice for oceanfront, lakeside, or high-humidity construction where nail corrosion leads to staining, weakening, or fastener failure over time.
• The annular ring shank addresses one of the most common structural concerns with box nails - gradual withdrawal under dynamic loads - by mechanically locking into the surrounding wood fibers for a grip that stays secure season after season.
• Stainless steel nails in this configuration are specifically recommended for permanent wood foundation construction under ANSI/AF&PA Permanent Wood Foundations Design Specifications, making them a specification-grade choice for code-sensitive projects.
• The checkered head pattern is a practical finish-quality detail that sets these nails apart in visible or semi-visible applications - the texture hides the nail face in wood grain and eliminates unsightly glare that bare steel heads can produce in exterior settings.

Frequently Asked Questions

What makes type 316 stainless steel preferable to type 304 for outdoor nailing applications?

Type 316 stainless steel contains molybdenum, which significantly enhances its resistance to chlorides and salt-laden moisture. Simpson specifically recommends 316 stainless nails for seaside applications and any project where superior corrosion resistance is required - such as coastal decking, docks, or exterior cladding exposed to marine air.

How does the annular ring shank improve holding power compared to a smooth shank?

The annular ring shank features a series of rings along the shank that bite into wood fibers as the nail is driven. These rings create a mechanical interlock that resists nail withdrawal far more effectively than a smooth shank. This is especially valuable in applications subject to seasonal wood movement, wind uplift, or repeated vibration loads.

Are these nails suitable for use in permanent wood foundation construction?

Yes. Stainless steel nails of this type are recommended for the construction of permanent wood foundations in accordance with the ANSI/AF&PA Permanent Wood Foundations Design Specifications. The combination of 316 stainless steel corrosion resistance and annular ring shank withdrawal performance makes them appropriate for this specification-grade application.

Will the checkered head pattern affect how well the nail accepts paint or stain?

The checkered pattern on the head is specifically designed to accept surface finishes. It provides texture that helps paint, stain, or other coatings bond to the nail head, reducing the risk of a bare, reflective spot on a finished surface. It also blends more naturally with wood grain than a smooth, polished head.
