Simpson 16d x 3-1/2" Sienna Painted Siding Nail in Type 304 Stainless Steel is a premium-quality fastener engineered by Simpson for attaching cedar, redwood, and cypress siding materials. The Sienna painted finish and checkered head pattern help the nail head blend seamlessly into wood siding textures, delivering a cleaner, more professional appearance on finished exteriors. Built from Type 304 stainless steel with an annular-ring shank, this 16d siding nail provides strong, long-lasting holding power in wood siding applications.

Key Features

• Type 304 Stainless Steel material - provides corrosion resistance for exterior wood siding applications, helping fasteners hold up in outdoor environments over time
• Sienna painted finish - color-matched coating helps nail heads blend with siding material, reducing the visual impact of fasteners on finished wood siding
• Checkered head pattern - the checker texture on the full round head blends with natural wood grain, further concealing the fastener once driven
• Annular-ring shank - the ring shank increases withdrawal resistance compared to smooth shank nails, creating a more secure attachment in cedar, redwood, and cypress siding
• Diamond point tip - sharp diamond point allows for easier driving and reduces splitting risk in wood siding material
• 11-gauge, 0.120" shank diameter - slender gauge makes driving easier while still delivering the holding strength needed for wood siding fastening
• 3-1/2" length (16d penny size) - provides sufficient penetration depth for secure attachment of thick wood siding profiles
• 1/4" full round head diameter - broad, flat head provides a consistent bearing surface against the siding face for a flush, finished look
• Made in the United States - domestically manufactured to consistent quality standards

Why This Product

• Designed specifically for natural wood siding - the combination of the Sienna paint, checkered head, and diamond point makes this nail purpose-built for cedar, redwood, and cypress siding, not a general-purpose fastener repurposed for the job
• Minimizes visible fastener appearance - the Sienna painted finish and checkered head texture work together to help nail heads visually disappear into wood siding surfaces, preserving the aesthetic of the finished installation
• Annular-ring shank adds holding power - ring shank geometry increases withdrawal resistance over smooth shank alternatives, helping siding stay firmly attached through seasonal wood movement and weather exposure
• Type 304 stainless steel for outdoor durability - stainless steel construction provides corrosion resistance suited to exterior wood siding applications, helping prevent unsightly rust staining on finished siding over time

Frequently Asked Questions

What types of wood siding is this nail designed for?

This painted siding nail is designed specifically for use with cedar, redwood, and cypress siding materials. The diamond point and slender 11-gauge shank help reduce splitting in these wood species during installation.

Why does the head have a checkered pattern?

The checker pattern on the full round head is designed to blend with natural wood texture. Combined with the Sienna painted finish, it helps the nail head visually disappear into the siding surface for a cleaner finished appearance.

What is the advantage of an annular-ring shank over a smooth shank on siding nails?

An annular-ring shank increases withdrawal resistance compared to a smooth shank nail. This means the nail holds more securely in the siding material and is less likely to back out over time due to seasonal wood movement or weather exposure.

Is Type 304 stainless steel appropriate for all exterior siding applications?

Type 304 stainless steel provides corrosion resistance suitable for most exterior wood siding applications. For seaside or coastal environments where exposure to salt air is a concern, Type 316 stainless steel is generally recommended for superior corrosion resistance in those more demanding conditions.
