Simpson 5d Cedar Trim Nail in Type 316 Stainless Steel is a precision-engineered finishing nail designed specifically to fashion woven corners in cedar trim and exterior millwork applications. Built by Simpson Strong-Tie and manufactured in the United States, this 1-3/4" annular-ring shank nail combines an ultra-thin wire profile with a blunt diamond point and checkered round head to deliver secure, low-visibility fastening in demanding outdoor environments. The Type 316 stainless steel construction provides superior corrosion resistance, making this trim nail an ideal choice for seaside installations, humid climates, and any exterior project where long-term durability is essential.

Key Features

• Type 316 Stainless Steel material - offers superior corrosion resistance compared to standard stainless grades, making it well suited for coastal and saltwater-exposed applications where rust-prone fasteners would fail prematurely.
• Ultra-thin 0.072" shank diameter - minimizes material displacement when driving into cedar and other trim substrates, reducing the risk of splitting delicate finish wood.
• Blunt diamond point - further reduces shingle and trim splitting on entry, preserving the integrity of fine exterior millwork and finished surfaces.
• Annular-ring shank - provides enhanced withdrawal resistance compared to smooth-shank nails, keeping trim securely fastened through seasonal expansion, contraction, and moisture cycling.
• Unobtrusive 9/64" checkered round head - the small head diameter keeps the nail nearly invisible after setting, delivering a clean finish look appropriate for visible trim and millwork installations.
• 15-gauge wire - strikes the right balance between nail strength and minimal kerf, giving installers driving confidence without overloading fine trim pieces.
• 1-3/4" length (5d penny size) - sized for cedar trim and woven corner applications where a shorter, precise fastener is required to hold without over-penetrating or blowing through thin material.

Why This Product

• Type 316 stainless steel is the material of choice for exterior and marine environments - if you are working near the coast, on a deck, or anywhere with persistent moisture exposure, this nail resists the corrosion that degrades standard galvanized or 304-grade fasteners over time.
• The cedar trim nail was specifically designed to fashion woven corners - this is not a general-purpose finish nail adapted for trim work, but a purpose-built fastener engineered for that exact application, giving installers confidence in the fit and performance.
• The combination of a diamond point, thin shank, and small checkered head makes this nail suitable for fine exterior finishing and millwork where wood splitting and visible fastener heads are both unacceptable outcomes.
• The annular-ring shank adds holding power that smooth-shank trim nails cannot match - once driven, these nails resist withdrawal forces caused by wood movement, weather, and long-term structural stress in outdoor trim assemblies.

Frequently Asked Questions

Why should I choose Type 316 stainless steel over other nail materials for exterior trim?

Type 316 stainless steel provides a higher level of corrosion resistance than standard galvanized or Type 304 stainless fasteners. It is specifically recommended for seaside applications and environments with prolonged moisture or chemical exposure, where lesser materials would corrode and stain or compromise the cedar trim over time.

What makes the annular-ring shank important for cedar trim fastening?

The annular-ring shank creates mechanical interlock with the surrounding wood fibers as the nail is driven. This significantly increases withdrawal resistance compared to a smooth-shank nail, which is especially valuable in outdoor trim where wood expands and contracts seasonally and fasteners can work loose over time.

Is this nail designed for a specific application, or is it a general finish nail?

This nail is specifically designed to fashion woven corners in cedar trim installations. Its ultra-thin 0.072" shank, 9/64" round head, and blunt diamond point are all engineered to minimize splitting and remain unobtrusive in finish carpentry and exterior millwork work.

How many nails are in a pound of these Simpson cedar trim nails?

There are approximately 400 nails per pound for this 5d, 15-gauge, 1-3/4" cedar trim nail.
