Simpson Structural Screws

Structural screws are a strong and efficient type of construction screw and convenient alternative to traditional lag screws. You can install them without needing to drill a pilot hole, saving you precious time on the job site.


SDWS Flat Head Structural Screws are suitable for timber, log, and framing applications. They’re easy to install and provide a high-strength alternative to through-bolting and traditional lag screws.


SDWH Hex Head Structural Screws are a great choice if a hex-head drive is preferred. These construction screws are available in a variety of options so you can be sure to find the one that meets your needs.


SDWC Truss Screws are used to provide stud-to-bottom plate or stud-to-top plate connections, along with fastening trusses and rafters to top plates.


SDW Multi-Ply Truss Screws are specifically designed for joining plated trusses and solid sawn lumber. No pre-drilling is required, so they install easily.


SD and SDS Connector Screws are specifically designed to replace nails in certain applications. They are load-rated, with load values typically exceeding 10d or 16d common nails. They are easier to install than nails in some applications and feature a galvanized coating making them ideal for both interior and exterior applications.
