Simpson Strong-Tie 0.131" x 2-1/2" 33 deg. Smooth Shank Connector Nail - Hot-Dip Galvanized is a pneumatic-driven structural fastener engineered specifically for use with Simpson Strong-Tie hardware connectors. Replacing traditional hand-driven 8d common nails, this 10-gauge paper-tape collated nail lets contractors and framers work faster and more accurately using a pneumatic nailer with a hole-locating mechanism - delivering consistent seating depth and full load values in connector applications. The hot-dip galvanized finish provides reliable corrosion resistance, making these nails well suited for treated lumber environments and outdoor framing projects.

Key Features

• 33 deg. collation angle with paper tape strips - compatible with a wide variety of popular pneumatic nailers, reducing downtime and tool-switching on the job site
• Full round head (0.285" diameter) with smooth head pattern - engineered to seat flush and bear full load against connector plates, achieving maximum rated load values in Simpson Strong-Tie connector applications
• Smooth shank, 0.131" diameter, 10 gauge - precisely sized to fit the pre-punched holes in Simpson Strong-Tie connectors, ensuring proper engagement and structural integrity
• Hot-dip galvanized coating - provides a thick, durable zinc barrier that resists corrosion when fastening connectors in outdoor, exposed, or pressure-treated lumber applications
• 2-1/2" length (8d penny size) - a direct pneumatic replacement for 8d common nails in compatible Simpson Strong-Tie connector installations, maintaining equivalent penetration depth
• Made in the United States - manufactured to consistent quality standards, supporting reliable performance in structural framing and connector work

Why This Product

• Tested and approved specifically for use in many popular Simpson Strong-Tie connectors - this is not a general-purpose nail adapted for connectors, but a purpose-built fastener that meets Simpson's structural load requirements straight out of the box
• The 33 deg. paper tape collation replaces hand-driven 8d, 10d, and 16d common nails in connector applications, so framing crews can transition from hammers to pneumatic nailers without sacrificing code-compliant performance
• A full round head combined with smooth shank geometry means every nail seats correctly in the connector hole, reducing the risk of off-angle fastening that can compromise structural connections
• Hot-dip galvanized finish adds meaningful corrosion protection for framing in humid, outdoor, or chemically treated wood environments - keeping the connection structurally sound long after installation

Frequently Asked Questions

Can these nails be used with standard framing nailers?

These nails feature a 33 deg. collation angle with paper tape strips, which are compatible with a wide variety of popular pneumatic nailers. For best results, pneumatic nailers equipped with a hole-locating mechanism are recommended, as they improve placement accuracy when fastening through the pre-punched holes in Simpson Strong-Tie connectors.

Are these nails a direct substitute for hand-driven 8d common nails in connector installations?

Yes. This connector nail is specifically designed to replace 8d common nails in compatible Simpson Strong-Tie connector applications. The full round head, smooth shank, and 0.131" shank diameter are engineered to deliver equivalent load performance to hand-driven nails when installed with an approved pneumatic nailer.

Is the hot-dip galvanized finish suitable for pressure-treated lumber?

Hot-dip galvanized nails provide a robust zinc coating that resists corrosion and is commonly used in applications involving treated lumber, outdoor framing, and moisture-exposed environments. The hot-dip process applies a thicker zinc layer than electroplating, making these nails appropriate for structural connector work in demanding conditions.

Which Simpson Strong-Tie connectors are these nails approved for?

These nails have been tested and approved for use in many popular Simpson Strong-Tie connector products. Simpson Strong-Tie's connector nail line is designed to replace 8d, 10d, and 16d common nails across a variety of their connector applications. For a specific connector, refer to the Simpson Strong-Tie product documentation for that hardware to confirm fastener requirements.
