Simpson Strong-Tie .148" x 2-1/2" 33 deg. SCN Smooth Shank Connector Nail in Hot-Dip Galvanized is a pneumatic-collated structural connector nail engineered as a direct replacement for hand-driven 10d common nails in Simpson Strong-Tie connector applications. Collated at 33 deg. on paper tape strips, these nails are compatible with a wide variety of popular pneumatic nailers, letting installers work faster and more consistently than traditional hand-nailing methods. The hot-dip galvanized finish provides strong corrosion resistance, making these nails well-suited for outdoor framing, treated lumber environments, and structural connector installations where long-term performance matters.

Key Features

• Hot-Dip Galvanized coating - provides robust corrosion resistance for outdoor use and compatibility with pressure-treated lumber, extending the service life of structural connections
• 33 deg. paper tape collation - works with a wide range of popular 33 deg. pneumatic nailers, enabling faster, more consistent connector fastening compared to hand-driving
• Full round head with smooth head pattern (0.285" diameter) - maximizes bearing surface against connector steel for full load-transfer performance in structural applications
• Smooth shank, 0.148" diameter (9 gauge) - sized to meet the requirements tested and approved for use with many popular Simpson Strong-Tie connector products
• 2-1/2" length (10d penny size) - replaces 10d common nails in approved Simpson Strong-Tie connector applications, maintaining code-compliant installation standards
• Pneumatic-driven design - nailers with hole-locating mechanisms allow precise placement in connector slots, improving installation efficiency and reducing installer fatigue over large jobs

Why This Product

• Tested and approved for Simpson Strong-Tie connectors - these nails have been specifically tested for use with many popular Simpson Strong-Tie products, so installers can trust that using them maintains the structural integrity and load ratings of the connector system - not a general-purpose substitute
• A genuine pneumatic alternative to hand-nailing - designed from the ground up to replace hand-driven 8d, 10d, and 16d common nails in connector applications, this nail line bridges the gap between jobsite efficiency and code-compliant structural fastening
• Hot-dip galvanized finish for lasting corrosion resistance - unlike electroplated coatings, hot-dip galvanizing delivers a thicker zinc layer, making these nails a reliable choice in moisture-exposed framing and outdoor structural applications
• 33 deg. angle compatibility with broad nailer support - the 33 deg. collation angle is one of the most widely used in the framing industry, so these nails integrate easily into existing pneumatic tool setups without requiring specialized equipment

Frequently Asked Questions

Can these nails replace standard 10d common nails in Simpson Strong-Tie connector installations?

Yes. These .148" x 2-1/2" smooth shank connector nails have been tested and approved as a pneumatic-driven alternative to hand-driven 10d common nails in many popular Simpson Strong-Tie connector applications. Using nails that have been specifically tested with the connector maintains the rated load values of the connection.

What collation angle and type are these nails, and which nailers are they compatible with?

These nails are collated at 33 deg. on paper tape strips. The 33 deg. collation angle is widely used in the framing industry and is compatible with a broad range of popular pneumatic nailers. Pneumatic nailers that feature a hole-locating mechanism are especially well-suited for connector nail applications, as they allow precise placement in the connector holes.

Why is hot-dip galvanizing specified for structural connector nails?

Hot-dip galvanizing applies a thick zinc coating to the nail, offering strong protection against corrosion in outdoor framing environments and when used with pressure-treated lumber. This finish is specified for structural connector nails to help ensure the long-term integrity of the connection under real-world conditions including moisture exposure.

What head type do these connector nails have, and why does it matter for load performance?

These nails feature a full round head with a smooth head pattern and a head diameter of 0.285 in. The full round head is the best choice for achieving full load values when installing connectors, as it maximizes the bearing surface against the connector steel - an important factor in maintaining the structural performance ratings of Simpson Strong-Tie connectors.
