An Innovation to Attach Tops of Interior Walls
Roof and/or floor trusses should not be fixed attached to tops of non-load bearing interior walls. In a previous article, I discussed a possible solution to this challenge (please read: https://www.hansenpolebuildings.com/2016/01/attaching-interior-walls-to-trusses/).
Those brilliant engineering type folks at Simpson may just have invented a better mouse trap for these situations.
Introducing the Strong-Drive SDPW Deflector Screw from Simpson Strong-Tie — a premium structural fastening solution for connecting non-load-bearing walls to trusses and joists. With tested lateral-load ratings that meet building code requirements, the SDPW screw is value engineered for strength, installation speed and safety. Offset Driver Bits and a driver extension (available in 18” and 30” lengths, each sold separately) maximize installation speed and safety while minimizing installed cost. The SDPW’s polymer sleeve allows for sliding during deflection, preventing squeaks. The SDPW is designed for superior performance, and it’s backed by the best service and product support in the industry.
