Simpson Strong-Tie HDU8-SDS2.5 Holdown

These are pre-deflected during the manufacturing process, virtually eliminating deflection under load due to material stretch. No stud bolts to countersink at openings. SDS screws are supplied with the holdowns to ensure proper fasteners are used. Use 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. Galvanized for extra corrosion resistance.
