Product Description
The Simpson CCTQM5.50-SDSG is a T-shape embedded column cap built for raised pier foundations and structural installations where heavy timbers bear directly on concrete or concrete block columns. Fabricated from 7-gauge steel with a hot-dip galvanized finish, this connector delivers the corrosion resistance demanded by exterior environments and treated-wood applications. The heavy-gauge beam seat works in conjunction with Simpson Strong-Tie SSTB anchor bolts to provide the high uplift and lateral resistance needed to help resist high-wind events. Positioned for non-corner, along-beam locations, the CCTQM includes a side stirrup that accommodates intermediate support beams joining at 90 deg. angles - making it the right fit for floor support beam runs that also require perpendicular intermediate connections.
Key Features
- SDS screw configuration engineered for high uplift design values - fasteners are positioned to maximize uplift resistance, giving you greater confidence in performance under high-wind loading conditions.
- Certified welds throughout - weld quality is verified to meet strength and load requirements, so structural integrity is not left to chance.
- SSTB offset allows flush installation to the edge of the pier - the anchor bolt offset keeps the cap properly aligned at the pier edge without awkward repositioning or shimming.
- SSTBs spaced to fit standard CMU cells - anchor bolt spacing matches standard concrete masonry unit cell layouts, simplifying installation in concrete block column applications.
- 5-1/2 in. main channel and side stirrup widths with a 13-1/2 in. main channel length - these proportions accommodate heavy timber framing while the T-shape geometry supports intermediate beams at 90 deg. angles from a single connector.
- 7-gauge steel construction - heavy-gauge material provides the load-bearing strength required for pier foundation and raised-floor structural connections.
- Hot-dip galvanized finish - HDG coating delivers extra corrosion resistance compared to standard finishes, making this cap suitable for exterior use and direct contact with pressure-treated lumber.
- Includes 20 Strong-Drive SDS Heavy-Duty Connector screws with no pre-drilling required - the included fasteners feature a corrosion-resistant double-barrier coating and drive directly into the connector holes, reducing installation time and labor on the job site.
Why This Product
- Purpose-built for high-wind, heavy-timber pier foundations - the combination of a heavy-gauge beam seat and SSTB anchor bolt system is specifically designed to deliver the high uplift and lateral resistance needed in wind-prone regions, not just general light-frame applications.
- T-shape geometry solves a real framing challenge - the integrated side stirrup handles intermediate beam connections at 90 deg. angles in a single connector, eliminating the need for additional hardware at non-corner floor support beam locations.
- Everything needed for installation is included - the 20 Strong-Drive SDS screws are packaged with the cap, and their no-pre-drill design means fewer tools and fewer trips to the truck during installation.
- HDG coating and certified welds mean long-term reliability - hot-dip galvanization protects against corrosion in exterior and treated-wood environments, while certified welds provide verified load-carrying confidence from day one.

Frequently Asked Questions
- What type of foundation application is the CCTQM5.50-SDSG designed for?
- This column cap is designed for raised pier foundations and applications where heavy timbers rest on concrete or concrete block (CMU) columns. It is intended for non-corner, along-beam locations and features a side stirrup that accommodates intermediate support beams joining at 90 deg. angles, making it suitable for floor support beam runs that require perpendicular intermediate connections.
- What fasteners are included, and is pre-drilling required?
- The CCTQM5.50-SDSG includes 20 Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screws (1/4 in. x 2-1/2 in.). These screws require no pre-drilling and feature a corrosion-resistant double-barrier coating. They are configured to provide high uplift design values.
- What are the key dimensions and material specs of this column cap?
- The main channel and side stirrup are each 5-1/2 in. wide, and the main channel length is 13-1/2 in. The connector is made from 7-gauge steel and features a hot-dip galvanized (HDG) finish for extra corrosion resistance, making it suitable for exterior environments and treated-wood applications.
- Is this column cap compatible with standard CMU (concrete masonry unit) block columns?
- Yes. The SSTB anchor bolt spacing is sized to fit standard CMU cells, and the SSTB offset geometry allows flush installation to the edge of the pier. This design ensures a clean, code-ready installation on standard concrete block columns.
