Simpson Strong-Tie HDUE17-SDS4.5HDG HDUE™ 27-7/8 in. Hot-Dip Galvanized Predeflected Holdown with Strong-Drive® SDS Screws

Simpson Strong-Tie HDUE17-SDS4.5HDG

•Predeflected seat reduces deflection under load
•Angled fastening engages the screws in tension for higher load capacity, reducing the number of screws required
•Angled fastening tabs help drive the fastener at a 45° angle, and offset holes on the second back plate block the fastener from being driven straight
•Overlapping back plate increases fastener strength and shear values, helping prevent post splitting
•Optimized screw patterns reduce splitting at the end of the post and maximize individual fastener capacity
•Extruded seat adds a greater cross-sectional steel section for added strength
•Teardrop holes allow higher and more even distribution of load
•Height: 27-7/8 in.
•Made from 10-gauge steel; hot-dip galvanization (HDG) offers extra corrosion resistance for exterior and treated-wood applications
