Product Description
The Simpson Strong-Tie CBSQ46-SDS2 4x6 Column Base Quick-Install with SDS2 Screws is engineered to serve as the critical connection between structural columns and concrete foundations. Designed for 4x6 lumber, this column base transmits structural loads directly to the foundation footing, making it a reliable choice for deck posts, basement columns, and other load-bearing applications where moisture exposure or weather conditions must be accounted for. Its G90 Galvanized finish and included Strong-Drive SDS Heavy-Duty Connector screws make this an efficient, code-conscious solution for contractors and builders seeking a faster, dependable post base installation.
Key Features
- 1 in. standoff height - meets code requirements for structural posts installed in basements or locations exposed to weather or water splash, helping protect the base of the column from moisture contact
- Included Strong-Drive SDS Heavy-Duty Connector screws - allow for faster installation than traditional bolts, so contractors spend less time on each post base and more time moving the project forward
- SDS screws provide a greater net section area of the column - compared to bolts, reducing material loss in the column and helping maintain the structural integrity of the post
- Reduced reveal with SDS fasteners - results in a cleaner, lower-profile installation that improves the finished appearance of the connection
- G90 Galvanized finish - provides corrosion resistance suited to the demanding environments where structural post bases are commonly installed
- Sized for 4x6 lumber - delivers a precise fit for the intended column size, eliminating guesswork and ensuring a secure, code-compliant connection at the post-to-footing interface
Why This Product
- Faster, screw-based installation - the included Strong-Drive SDS Heavy-Duty Connector screws replace traditional bolts entirely, cutting installation time and simplifying the process for both new construction and replacement projects
- Built-in moisture protection - the 1 in. standoff keeps the base of the column elevated above the concrete surface, addressing code requirements for weather-exposed and basement post installations without needing additional hardware
- Stronger column cross-section - by using SDS screws instead of bolts, the column retains more of its net section area, helping preserve the full load-carrying capacity of the structural post
- Corrosion-resistant construction - the G90 Galvanized finish is well-suited to the conditions these column bases are designed for, supporting long-term performance in environments where moisture and exposure are ongoing concerns
