The Simpson CCQ44SS-SDS2.5 is a stainless-steel column cap engineered to deliver strong, reliable column-beam connections in wood construction. Designed for 4x beams and 4x posts, this heavy-duty connector features an extended seat that provides additional bearing surface area beyond each side of the column, helping distribute load from the beam and reinforcing the connection at its most critical point. Built from 7-gauge stainless steel with certified welds, the CCQ44SS-SDS2.5 is ideal for high-corrosion and severe-corrosion environments where long-term structural integrity is essential. It comes complete with 1/4 in. x 2-1/2 in. stainless-steel Strong-Drive SDS Heavy-Duty Connector screws (Model SDS25212SS) for fast, code-compliant installation without the need for additional brackets or braces.

Unlike traditional bolt-through installations, the included SDS screws attach to a greater net section area of the column, delivering superior load performance with a lower profile. Uplift load values have been engineered to meet the demands of earthquake and wind loading conditions, making this cap a trusted choice for demanding structural applications.

Key Features

• Lower Profile Installation: SDS screws provide a lower profile than standard through bolts while engaging a greater net section area of the column.
• Certified Welds: Every weld is certified for confidence in strength and load performance.
• Increased Uplift Loads: Uplift load values have been increased to address earthquake and wind loading requirements.
• Diamond Holes: Included diamond holes allow for convenient temporary fastening during installation.
• High/Severe Corrosion Resistance: Constructed from stainless steel for use in high-corrosion and severe-corrosion environments.
• 7-Gauge Steel Construction: Heavy-duty 7-gauge stainless steel provides superior structural strength.
• Extended Bearing Seat: The seat extends beyond each side of the column to distribute beam load more effectively.
• No Additional Hardware Needed: Accommodates the connection generally without the need for additional brackets or braces.

Frequently Asked Questions

What beam and post sizes is this column cap designed for?

The CCQ44SS-SDS2.5 is designed for a nominal 4x beam width and a nominal 4x post size, making it specifically suited for wood construction connections using those member sizes.

What fasteners are included, and how many are needed for installation?

The column cap includes 1/4 in. x 2-1/2 in. stainless-steel Strong-Drive SDS Heavy-Duty Connector screws (Model SDS25212SS). Installation requires 30 of these screws. Note that stainless-steel fasteners are required when installing stainless-steel connectors.

Why is stainless steel used for this column cap, and where is it best suited?

This column cap is made from 7-gauge stainless steel, which provides high and severe corrosion resistance. It is best suited for environments where exposure to moisture, salt, or other corrosive elements makes standard steel connectors unsuitable for long-term structural integrity.

How do the SDS screws compare to traditional through-bolt installation?

The Strong-Drive SDS screws provide a lower profile than standard through bolts and attach to a greater net section area of the column than a bolt attachment normally allows. This results in superior load performance while simplifying installation.
