Product Review

Simpson Strong-Tie HDU8-SDS2.5 Holdowns are pre-deflected during the manufacturing process, virtually eliminating deflection under load due to material stretch. They come with 2-1/2-inch Simpson Strong-Tie Strong-Drive SDS screws which install easily and provide reduced fastener slip. Using SDS screws results in a greater net section, when compared to bolts, as no material is removed.
