Simpson 16d x 3-1/2" Dark Brown Painted Siding Nail in 304 Stainless Steel is a premium-quality fastener engineered for cedar, redwood, and cypress wood siding applications. Built from Type 304 stainless steel with a dark brown painted finish, these nails are designed to fasten wood siding securely while keeping fastener heads visually discreet against the siding surface. The annular-ring shank, diamond point, and checkered head pattern work together to deliver both holding power and a clean, professional appearance on exterior siding projects. Made in the United States, this fastener is a trusted choice for contractors and builders who demand durability and a finished look in wood siding installations.

Key Features

• Type 304 Stainless Steel material - provides strong corrosion resistance for long-lasting performance in exterior wood siding applications exposed to moisture and weather
• Dark brown painted finish - helps fastener heads blend seamlessly with cedar, redwood, and cypress siding, reducing the visual impact of nail heads on the finished surface
• Checkered head pattern - designed to mimic natural wood texture, allowing the full round head to disappear into the look of the siding material rather than stand out
• Annular-ring shank - dramatically increases withdrawal resistance compared to smooth-shank nails, keeping siding boards locked in place even through seasonal wood movement and weather cycles
• Diamond point tip - reduces splitting risk when driving through cedar, redwood, and cypress, making installation smoother and protecting the integrity of the siding material
• 11-gauge, 3-1/2" length (16d penny size) - the slender gauge allows easier driving while the length provides substantial penetration depth for a secure hold in wood siding framing
• Full round head with 1/4" head diameter - distributes holding force across the siding face while keeping the head profile low and unobtrusive on the finished wall

Why This Product

• Engineered specifically for cedar, redwood, and cypress siding - the combination of stainless steel material, annular-ring shank, and diamond point addresses the unique demands of these wood species, which can be prone to splitting and require strong long-term fastener retention
• Painted finish eliminates the "silver dot" problem on dark siding - standard bright nails leave visible metallic heads on stained or natural wood siding; the dark brown painted head blends in to maintain a clean exterior appearance
• Annular-ring shank delivers superior grip versus smooth-shank alternatives - the ring shank mechanically locks into wood fibers, resisting the nail pullout that can occur as exterior siding boards expand and contract with seasonal temperature changes
• American-made from Type 304 stainless steel - offers reliable corrosion resistance suited to exterior siding applications, with a domestic quality standard that supports demanding residential and commercial projects

Frequently Asked Questions

What wood siding materials are these nails designed for?

These painted siding nails are designed specifically for cedar, redwood, and cypress siding material - three species commonly used in exterior wood siding applications that benefit from the annular-ring shank's strong withdrawal resistance and the diamond point's reduced splitting tendency.

Why does the nail have a checkered head pattern and painted finish?

The checkered head pattern is designed to blend with natural wood texture, and the dark brown painted finish helps the nail head visually match the siding surface. Together, these features minimize the appearance of fastener heads on the finished exterior wall for a cleaner, more professional look.

What is the difference between an annular-ring shank and a smooth shank on a siding nail?

An annular-ring shank has ridges along the shank that mechanically interlock with wood fibers, significantly increasing withdrawal resistance compared to a smooth shank. This helps keep siding boards firmly fastened even as the wood naturally expands and contracts with changes in temperature and moisture.

Should I use Type 304 or Type 316 stainless steel nails for my siding project?

Type 304 stainless steel provides strong corrosion resistance and is well-suited for most exterior wood siding applications. If your project is in a coastal or seaside environment with elevated salt air exposure, Type 316 stainless steel offers superior corrosion resistance for those more demanding conditions - these nails are Type 304.
