Simpson Strong-Tie .131" x 1-1/2" 33 deg. SCN Smooth Shank Connector Nail in Hot-Dip Galvanized is engineered as a pneumatic-driven alternative to hand-driven fasteners for use with structural connectors. Designed and tested by Simpson Strong-Tie, this 8d smooth shank nail is collated at 33 deg. on paper tape strips, making it compatible with a wide variety of popular pneumatic nailers. The hot-dip galvanized finish delivers corrosion resistance suited for outdoor and pressure-treated lumber applications, while the full round head profile ensures optimal load transfer when securing Simpson Strong-Tie hardware and connectors.

Key Features

• 33 deg. paper tape collation - compatible with a wide range of popular pneumatic framing nailers, so installers can drive nails quickly and consistently without manual collation concerns.
• Smooth shank design - delivers reliable holding power in connector applications and allows clean, consistent seating flush with the connector plate surface.
• Full round head (0.285" diameter) - provides maximum bearing surface against connector flanges, helping achieve full load values when installing Simpson Strong-Tie structural connectors.
• 10-gauge, .131" shank diameter - matches the dimensional requirements of tested and approved Simpson Strong-Tie connector applications, replacing 8d common nails where pneumatic driving is preferred.
• Hot-dip galvanized coating - provides enhanced corrosion resistance compared to electroplated finishes, making these nails well-suited for exterior connector installations and treated lumber environments.
• Tested and approved for use in Simpson Strong-Tie connectors - gives installers confidence that performance meets the structural requirements of the connector system, supporting code-compliant installations.
• 1-1/2" length (8d penny size) - sized to replace 8d common nails in a variety of connector applications, offering a direct and tested pneumatic substitute without sacrificing structural integrity.

Why This Product

• Pneumatic nailers with a hole-locating mechanism are often more convenient and efficient than hand driving - this nail line is specifically designed to support that workflow while maintaining tested load values in Simpson Strong-Tie connector applications.
• The 33 deg. paper tape collation format is compatible with a wide variety of popular pneumatic nailers from multiple manufacturers, reducing the chance of tool incompatibility on the job site.
• Because these nails have been tested and approved for use in many Simpson Strong-Tie products, they serve as a direct replacement for 8d, 10d, and 16d common nails in connector applications - simplifying material selection and keeping installations within approved parameters.
• The hot-dip galvanized finish offers a level of corrosion protection that supports use in outdoor structural connections, where fastener durability is critical to long-term performance.

Frequently Asked Questions

What type of nailer is this connector nail designed for?

This nail is designed for use with pneumatic nailers that accept 33 deg. paper tape collation. It is compatible with a wide variety of popular pneumatic nailers and is intended as a pneumatic-driven alternative to hand-driven common nails when installing Simpson Strong-Tie structural connectors.

Can this nail replace standard common nails in Simpson Strong-Tie connector applications?

Yes. The Simpson Strong-Tie structural connector nail line is designed to replace 8d, 10d, and 16d common nails in a variety of Simpson Strong-Tie connector applications. These nails have been tested and approved for use in many popular Simpson Strong-Tie products, making them a direct pneumatic substitute in approved connector installations.

Why is the hot-dip galvanized coating used on this nail?

The hot-dip galvanized finish provides corrosion resistance that makes these nails appropriate for outdoor structural connector applications and environments where fastener durability is important. Hot-dip galvanizing applies a thicker zinc coating than electroplating, which can help extend the life of the fastener in demanding conditions.

What is the head type on this connector nail, and why does it matter?

This nail features a full round head with a 0.285 in. head diameter. The full round head is the best choice for achieving full load values when installing structural connectors, as the larger bearing surface distributes force across the connector flange more effectively than clipped or offset head styles.
