Specifications
The Simpson Strong-Tie SDCF10X400-R25 SDCF TIMBER-CF screw by Simpson Strong-Tie is built to meet the structural demands of mass timber construction, including cross-laminated timber (CLT), glulam, and laminated veneer lumber (LVL). This fully threaded structural screw provides high-strength connections for demanding wood-to-wood applications, no pre-drilling required in most conditions.
Key Features:
- Fully Threaded Design: Ensures even load distribution across the full length of the screw, enhancing structural integrity in CLT and mass timber applications.
- Patented Four-Cut Tip: Allows quick starts and reduced splitting, no pre-drilling required in most applications.
- T-Drive Recess: Maximizes bit engagement, reducing cam-out and extending tool life.
- Heat-Treated Carbon Steel: Optimized strength for load-bearing connections in heavy timber.
- Double-Barrier Coating: Provides corrosion protection for use in interior and protected exterior environments.
Applications:
- CLT wall, floor, and roof panel connections
- Glulam beam and column assemblies
- LVL to LVL framing joints
- Wood-to-wood structural reinforcements in timber-frame construction
- Anywhere high-load wood fastening is required without the use of metal connectors
Installation:
- Use the provided T-40 driver bit for all screw sizes.
- Installation is smooth and fast with most standard impact drivers.
- Pre-drilling is generally not required due to the four-cut tip design, but may be recommended for extremely dense wood species.
- Ensure full embedment for optimal structural performance.
