Simpson Strong-Tie SDHR27614-R25 Strong-Drive® SDHR COMBO-HEAD Screw — 0.275 in. x 6-1/4 in., Blue Zinc (25-Qty)

The Strong-Drive® SDHR Combo-Head screw is a structural fastener designed for cross-laminated timber construction, mass timber construction and general interior applications. These partially-threaded, sturdy 0.390 in. and 0.470 in. outer-diameter structural fasteners are designed to pull structural members together while providing excellent connection strength. The unique “combination” head allows for effortless driving using either a hex driver bit or T40 6-lobe driver bit. The SDHR Combo-Head has an interior-grade, blue-zinc coating, a robust knurled shaft and Type-17 point for fast starts and low-torque driving.

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