The Simpson CCQM Hot-Dip Galvanized Column Cap for 5-1/2 in. Beam with Strong-Drive SDS Screws by Simpson is an embedded column cap engineered for raised-pier foundations and structural connections where heavy timbers bear on concrete or concrete block columns. Built from heavy 7-gauge steel and finished with hot-dip galvanization, this column cap delivers the high uplift and lateral resistance needed to help resist high wind events - making it the trusted choice of engineers and contractors for demanding timber-to-concrete connections in exterior and treated-wood environments.

Key Features

• Designed for non-corner, along-beam locations - positions correctly along a floor support beam where a straight cap is required, preventing installation errors at critical structural points
• 7-gauge steel construction - provides the heavy-duty strength needed to handle the substantial loads transferred by large timber members in pier foundation applications
• Hot-dip galvanized (HDG) finish - delivers extra corrosion resistance that stands up to exterior conditions and chemical exposure from pressure-treated lumber, extending the service life of the connection
• Strong-Drive SDS Heavy-Duty Connector screws included - install with no pre-drilling and feature a corrosion resistant double-barrier coating, saving setup time and ensuring a fastener-to-connector finish match in aggressive environments
• 5-1/2 in. main channel width and 11 in. channel length - sized specifically to seat a 5-1/2 in. beam securely, giving contractors a precise, engineered fit without field modification

Why This Product

• Everything needed for installation is in the box - the included Strong-Drive SDS screws eliminate a separate fastener purchase and are matched by Simpson to this connector for verified performance, so the connection goes together correctly the first time
• HDG protection where standard finishes fall short - hot-dip galvanization provides a level of corrosion resistance specifically suited to exterior pier foundation work and contact with treated wood, where lighter coatings degrade prematurely
• Engineered and tested for high uplift and lateral resistance - the heavy-gauge beam seat and SSTB-style anchor bolt design give this cap the structural capacity to help a building resist high wind events, supporting both code compliance and long-term safety
• A proven connector from a brand engineers specify by name - manufactured by Simpson to the same quality standards relied on across professional construction, this column cap brings tested, documented performance to raised-pier and heavy-timber applications

Frequently Asked Questions

What type of fasteners are required to install the CCQM5.50-SDSHDG, and are they included?

This column cap is fastened with Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screws, which are included with the product. These screws install with no pre-drilling and feature a corrosion resistant double-barrier coating.

Why is hot-dip galvanization used on the CCQM5.50-SDSHDG?

Hot-dip galvanization (HDG) offers extra corrosion resistance, making this column cap well suited for exterior applications and use with treated wood where standard finishes may not provide adequate protection.

Where is the CCQM5.50-SDSHDG designed to be used along a beam?

This column cap is intended for use along a floor support beam at non-corner locations. It is not designed for corner placement.

What steel gauge is used in the construction of the CCQM5.50-SDSHDG?

The CCQM5.50-SDSHDG is made from 7-gauge steel, providing the heavy-gauge beam seat necessary to deliver high uplift and lateral resistance needed to help resist high wind events.
