The Simpson 6X Post Cap, Stainless Steel BC6SS is a professional-grade connector engineered by Simpson to link a beam to a post with dependable uplift and lateral resistance. Built from 18-gauge stainless steel, this post cap is purpose-built for light-duty structural connections and accommodates both nominal and rough lumber in 6x post sizes, making it a reliable choice for decks, pergolas, and other outdoor framing applications where corrosion resistance is a priority.

Key Features

• Beam-to-post connection with uplift and lateral resistance - secures the joint against both lifting forces and side-to-side movement, keeping the structure stable under load.
• Opposing flanges for increased lateral resistance - the flange design adds an extra layer of structural integrity, reducing the risk of racking in demanding conditions.
• Compatible with common and pneumatic nail sizes - attains full allowable load using either nail type, giving installers flexibility without sacrificing rated performance.
• 18-gauge stainless steel construction - provides enhanced corrosion resistance compared to standard galvanized options, making this cap well-suited for moisture-prone or chemically exposed environments.
• Fits both nominal and rough 6x lumber - accommodates real-world lumber variations on the job site, reducing the need for adjustments or special ordering of alternate hardware.
• Made in the United States - domestic production supports consistent quality standards and reliable material sourcing.

Why This Product

• Stainless steel where it counts - for outdoor structural connections exposed to moisture, salt air, or harsh conditions, stainless steel construction delivers a meaningful durability advantage over standard coated connectors.
• Engineered by a trusted structural connector brand - Simpson has a well-established reputation for precision-engineered hardware, and the BC6SS reflects that commitment with rated uplift and lateral resistance built into a straightforward post cap profile.
• Installer-friendly design - compatibility with both common and pneumatic nails means crews can use the fasteners already on hand and still achieve full rated load capacity, keeping installations efficient.
• Versatile lumber fit - by accommodating both nominal and rough 6x post sizes, this connector works across a wider range of framing scenarios without requiring separate hardware for different lumber dimensions.

Frequently Asked Questions

What is the BC6SS post cap designed to do?

The BC6SS post cap is designed to connect a beam to a post. It provides both uplift and lateral resistance, making it suitable for light-duty structural connections using 6x nominal or rough lumber.

What size nails should be used to install the BC6SS?

Install using 0.162 x 3 1/2 inch nails or 0.162 x 2 1/2 inch nails. The connector is designed to attain its full allowable load with either common nail or pneumatic nail sizes. Always use all specified fasteners per the General Notes.

Can bolts be installed into the pilot holes on the BC6SS?

No. Do not install bolts into the pilot holes. Follow all installation guidelines and use only the specified nail fasteners to ensure the connection performs as intended.

What material is the BC6SS made from, and why does it matter?

The BC6SS is made from 18-gauge stainless steel. The stainless steel coating and material provides enhanced corrosion resistance compared to standard galvanized options, making it well-suited for environments where moisture or chemical exposure is a concern. The 18-gauge construction is specifically designed for light-duty applications.
