The Simpson 8d 2-3/8 in. Clipped Head Ring-Shank Collated Nail in Type 316 Stainless Steel is a professional-grade fastener built for framing applications where long-term holding power and corrosion resistance are both non-negotiable. Manufactured by Simpson, these 12-gauge collated nails feature an annular ring shank for superior withdrawal resistance and a smooth D-shaped clipped head designed to seat consistently during high-volume pneumatic nailing. Paper-tape collation at a 31 deg. - 34 deg. angle feeds cleanly through many major manufacturers' pneumatic framing tools, keeping production moving without interruption. Type 316 stainless steel construction makes these nails a dependable choice for coastal builds, marine structures, and any environment where standard fasteners are prone to premature corrosion.

Key Features

• Type 316 stainless steel finish - delivers severe-level corrosion resistance, making these nails well suited for coastal, marine, and high-humidity jobsites where fastener integrity must hold over time
• Annular ring shank - increases withdrawal resistance compared to smooth-shank nails, producing a secure, lasting attachment in structural framing assemblies
• Smooth D-shaped clipped head - seats flush and consistently for a clean finish, while the clipped profile allows tighter collation strip spacing for more nails per reload
• Paper-tape collation at 31 deg. - 34 deg. - compatible with many major manufacturers' pneumatic framing nailers in that angle range, reducing downtime from incompatible strips or misfires
• Diamond point tip - starts penetration precisely and reduces the likelihood of splitting, contributing to cleaner, more accurate driving in framing lumber
• 8d penny size, 2-3/8 in. length, 12 gauge - a commonly specified framing nail dimension that meets the requirements of general structural framing work
• 1,000-nail package quantity - provides a jobsite-ready supply suited for extended framing runs, reducing the frequency of restocking interruptions

Why This Product

• Severe-environment corrosion resistance built in - Type 316 stainless steel goes beyond standard stainless grades, offering the level of protection required in coastal, marine, and persistently damp environments where fastener corrosion is a real structural concern
• Ring shank holding power where it counts - the annular ring shank mechanically locks into wood fibers to resist withdrawal forces, making these nails a stronger choice than smooth-shank alternatives for framing connections subject to wind, load, and seasonal movement
• Broad pneumatic tool compatibility - the 31 deg. - 34 deg. paper-tape format works across many major brands of pneumatic framing nailers, so contractors are not locked into a single tool platform to use these fasteners
• Trusted Simpson engineering for professional framing - Simpson is a widely recognized name in structural fasteners and connectors, and this nail is part of their purpose-built collated nail line designed to meet the demands of professional framing applications
