Strong-Drive® SDHR Combo-Head Screw

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"- and 0.470"-diameter structural fasteners are designed to pull structural members together while providing excellent connection strength. The “combination” head allows for 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 shank and Type-17 point for fast starts and low-torque driving.

Key Features
  • Designed for use with steel side plates
  • Can be driven by either a hex-head or 6-lobe driver bit
  • Heavy-duty, partially threaded shaft with knurl provides strength, with superb pull-out resistance
  • Type-17 point ensures fast starts, reduces installation torque and eliminates the need for predrilling in most applications
