Simpson Strong-Tie Fiber-Cement Screws make it easy to install fiber-cement siding on your home projects. Designed with a wafer head and small cutting nibs that sink in flush without extra effort, leaving you with a smooth, clean look. Whether you’re fastening siding to panels or directly to wood, these screws help you get the job done right.

Each screw starts quickly thanks to a sharp Type-17 point, no pre-drilling in most cases. The coarse threads bite in strong and hold tight, keeping your siding secure for the long haul. Use the 1 1/4" screws for attaching siding to panels, or the 1 5/8" screws for fastening directly to wood. With a #2 square drive, your bit locks in place so you can drive each screw with less slipping and frustration.
