The Simpson 2-3x6 Post Cap with Double-Shear Nailing in Stainless Steel is a dual-purpose connector from Simpson engineered to handle light cap and base connections between a triple 2x beam and a 6x post. Built from 316L stainless steel, this post cap is purpose-built for high-moisture, coastal, and corrosive environments where standard hardware would be prone to premature degradation - delivering the corrosion resistance and structural reliability that demanding installations require.

Key Features

• Dual-purpose cap and base connector - functions as both a post cap and post base, giving installers flexibility to use a single hardware component across a wider range of light connection applications.
• 316L stainless steel construction - provides maximum corrosion resistance in harsh coastal and high-moisture environments, ensuring long-term performance where standard steel connectors would quickly fail.
• Double-shear nailing pattern - distributes load across multiple shear planes at the connection point, improving load transfer and overall joint integrity.
• Sized specifically for a triple 2x beam to 6x post connection - eliminates guesswork by matching exactly the structural member combination it is designed to serve, supporting accurate planning and code-compliant installations.
• Requires stainless steel fasteners - pairing the connector with matching stainless fasteners maintains the full corrosion-resistance system and preserves structural integrity over the life of the installation.
• Made in the United States by Simpson - backed by a manufacturer with a well-established reputation in structural connector engineering, supporting confidence in both quality and availability of technical documentation.

Why This Product

• Built for corrosive environments where standard hardware falls short - the 316L stainless steel material is specifically chosen for coastal, high-moisture, and chemically aggressive conditions, making this post cap a dependable long-term solution rather than a short-term compromise.
• One connector, two roles - the dual-purpose cap and base design means this single component can address light post cap or post base connections, reducing the number of different hardware pieces needed on a project.
• Engineered fit for a specific member pairing - because the connector is sized precisely for a triple 2x beam and a 6x post, contractors and builders can install with confidence that the hardware matches the structural members without field modification or guesswork.
• Double-shear nailing for stronger load transfer - the double-shear nailing configuration at both the beam and post flanges maximizes the connection's ability to handle the loads placed on it, supporting safer and more structurally sound framing assemblies.

Frequently Asked Questions

What size post and beam does the BCS2-3/6SS fit?

The BCS2-3/6SS is designed for a nominal connection of a triple 2x beam to a 6x post, making it suitable for structural applications requiring that specific member combination.

Why is 316L stainless steel used for this post cap?

316L stainless steel is specified to provide maximum corrosion resistance in the harshest climates, including coastal and high-moisture environments where standard steel hardware would be prone to premature corrosion and failure.

Are stainless steel fasteners required when installing the BCS2-3/6SS?

Yes. Stainless steel fasteners are required for installation. Using non-stainless fasteners with a stainless steel connector can compromise corrosion resistance and structural integrity at the connection point.

Is this post cap suitable for fence or unbraced carport installations?

No. Post bases in the BC series do not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for non top-supported installations such as fences or unbraced carports.
