These partially threaded, heavy-duty 10 mm (0.390\")- and 12 mm (0.470\")-diameter 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 friction-reducing, black e-coat finish and optimized hardness profile that mitigates embrittlement issues. A robust, knurled shank and Type-17 point allow for fast starts and low-torque driving, making it ideal for driving into wood without the need for predrilling. The SDHR screws are load rated for shear and withdrawal resistance and designed for dry-service applications.\u003c\/p\u003e\n\u003cul\u003e\n\t\u003cli\u003eBlack e-coat finish provides a
