The Simpson Strong-Drive® SDHR COMBO-HEAD Screw is engineered for robust performance in demanding applications, featuring a versatile design that can be driven with either a hex-head or 6-lobe driver bit for enhanced usability. With a deep T40, 6-lobe recess, it ensures a secure drive while allowing for a straightforward installation process, thanks to its Type-17 point that minimizes torque and often eliminates the need for predrilling. This screw boasts a heavy-duty, partially-threaded shaft with knurling for increased strength and pull-out resistance, making it ideal for use with steel side plates. Finished with a blue-zinc interior grade coating, it not only provides durability but also offers corrosion resistance suitable for various indoor projects, ensuring reliability when you need it most.
