Simpson Strong-Drive SCN Smooth Shank Connector Nail, 0.131" x 1-1/2", Hot-Dip Galvanized by Simpson Strong-Tie delivers reliable structural performance for connector installations in both interior and exterior environments. These 8d, 10-gauge full round head nails feature a hot-dip galvanized Class D coating that stands up to corrosive and wet-service conditions, making them a trusted choice for fastening Simpson Strong-Tie connectors where code compliance and long-term durability matter. The smooth shank profile and precision dimensions ensure consistent, flush seating in connector nail holes, reducing installation frustration and keeping projects on schedule.

Key Features

• Hot-Dip Galvanized, Class D coating - provides a thick, durable zinc barrier that resists corrosion in exterior, wet-service, and demanding application environments, extending the life of the fastened connection.
• 0.131" smooth shank diameter (10 gauge) - engineered to fit precisely in Simpson Strong-Tie connector nail holes, ensuring full bearing contact and predictable structural performance.
• Full round head with smooth head pattern, 0.280" head diameter - seats flush against connector flanges to maximize bearing area, reducing the risk of the nail pulling through under load.
• 1-1/2" length (8d penny size) - sized specifically for structural connector applications where nail length affects both holding power and proper member penetration depth.
• Complies with ASTM F1667 for metal hardware nails - meets established industry standards, supporting code-compliant installations on permitted projects.
• Head ID stamp for easy jobsite identification - allows inspectors and installers to quickly confirm the correct nail is in use, reducing the chance of failed inspections or costly re-work.
• Approximately 150 nails per pound - consistent count-per-pound helps estimators and contractors plan material quantities accurately and minimize waste.

Why This Product

• Designed specifically for Simpson Strong-Tie connector applications - the 0.131" shank diameter and 0.280" head diameter are matched to connector nail-hole geometry, so you get the intended structural performance without improvising with generic fasteners.
• Hot-dip galvanized Class D coating makes these nails suitable for corrosive and exterior environments where standard bright or electroplated nails would deteriorate prematurely and compromise the connection over time.
• ASTM F1667 compliance and head ID stamping simplify the inspection process - building officials can quickly verify the correct hardware is installed, keeping projects moving without hold-ups.
• Versatile 8d, 1-1/2" size covers a variety of connector types and framing situations, reducing the number of different nail SKUs a contractor needs to stock for mixed connector installations.

Frequently Asked Questions

What makes these nails different from standard smooth shank nails?

These Simpson Strong-Drive SCN nails are engineered to match the nail-hole geometry of Simpson Strong-Tie connectors, with a 0.131" shank diameter and 0.280" full round head diameter that provide optimal bearing and structural performance when used with the recommended connectors. They also carry a head ID stamp for easy field identification, which standard hardware nails typically do not have.

Are these nails suitable for exterior or corrosive environments?

Yes. The hot-dip galvanized Class D coating provides a thick zinc layer that resists corrosion, making these nails appropriate for exterior, wet-service, and corrosive application environments - not just dry interior use.

Do these nails meet any recognized standards?

Yes. These nails comply with ASTM F1667 for metal hardware nails, which supports their use in code-compliant structural connector installations. The head ID stamp also aids inspectors in verifying correct fastener use on the jobsite.

How many nails are in a pound, and why does that matter?

There are approximately 150 nails per pound for this size. Knowing the count-per-pound helps contractors and estimators calculate how much material is needed for a given number of connector installations, reducing both over-ordering and mid-project shortages.
