Simpson Strong-Tie SDHR10X100-R25 Strong-Drive® SDHR COMBO-HEAD Screw — 10 mm x 100 mm, Black E-Coat (25-Qty)

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.

This Simpson product is designed for construction, connector, fastening, anchoring, and structural applications where dependable performance, durability, and jobsite-ready installation matter.
