The Simpson Strong-Tie SDWC Truss Screw provides a truss and rafter-to-top plate connection, as well as a method to fasten studs to top or bottom plates.
The fully-threaded shank engages the entire length of the fastener, providing a secure connection.
The SDWC comes in two lengths. The shorter black one is for single top or bottom plates, and the longer orange one is for double top plates. They are different colours as a visual confirmation for building inspectors.
