Simpson Strong-Tie SDHR12X160 Strong-Drive® SDHR COMBO-HEAD Screw — 12 mm x 160 mm, Black E-Coat (100-Qty)
Product Description
The Simpson Strong-Tie® Strong-Drive® SDHR Combo-Head screw is a structural fastener designed for cross-laminated timber (CLT), mass timber construction and general interior applications. These partially-threaded, heavy-duty structural fasteners are designed to provide excellent connection strength, especially when connecting steel plate or angle connectors to wood. The unique “combination” head allows for the convenience of driving with either a hex-driver bit or 6-lobe driver bit. The SDHR Combo-Head has a black e-coat finish, a robust knurled shank, and a Type-17 point for fast starts and low-torque driving, making it ideal for self-drilling into wood without the need for predrilling. The SDHR screw is designed for dry-service applications.

Product Details
Key Features
- Black e-coat finish provides a construction-durable, nonmetallic and friction-reducing coating for corrosion resistance in interior dry-service conditions
- Optimized hardness profile helps mitigate field embrittlement issues, and is compliant with CSA O86:24 hydrogen embrittlement requirements
- Designed for use with steel side plates
- Can be driven by a 15 mm (SDHR10) or 17 mm (SDHR12) hex-head driver bit, or a T40 6-lobe driver bit
- Heavy-duty shank with robust knurl reduces installation torque
- Type-17 point ensures fast starts, reduces installation torque and eliminates the need for predrilling in most applications
- Hex head with deep T40, 6-lobe recess for a secure drive
- ICC-ES ESR-3046
Finish
- Black e-coat
Please note: The corrosion resistance of black e-coat is equivalent to hot-dip galvanization (ASTM A153, Class D) in wet service conditions during the construction period, described by ICC-ES AC257 Exposure Condition 3. In conditions with prolonged exposure to wet conditions, alternate coatings/materials should be considered.
Applications
- Metal-to-wood connections, including steel plate-to-sawn wood, glulam, cross-laminated timber (CLT), or composite lumber products
Product Includes
- Driver bit: BIT40T-134-R2
