Simpson Strong-Tie HDUE Series HDUE7-SDS3 Holdown, 14-11/16 in L, 2-7/8 in W, Steel, Zinc Galvanized

The patent pending HDUE holdown is designed to meet the increased design demands of today's residential wood structures, including three-story homes with more windows and limited shearwall space. Offering higher load capacities than previous models, the HDUE serves as an easy one-to-one replacement for our industry leading HDU. This holdown provides exceptional overturning resistance for shearwalls, braced wall panels and other lateral force-resisting applications in wood construction. The HDUE features a pre-deflected seat that reduces deflection under load, an overlapping back plate for increased strength and optimized screw patterns to prevent splitting. It's tested to ICC-ES AC155 standards. The higher-capacity models combine fasteners in both shear and tension while reducing the number of screws required. The HDUE installs with Strong-Drive® SDS heavy-duty connector screws, minimizing fastener slip and preserving the wood post's net section better than bolts. Pre-deflected seat reduces deflection under load Angled fastening in the four larger sizes engages the screws in tension for higher load capacity, reducing the number of screws required Angled fastening tabs in the four larger sizes help drive the fastener at a 45 deg 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 Installs with strong-drive SDS heavy-duty connector screws Extruded seat adds a greater cross-sectional steel section for added strength Teardrop holes allow higher and more even distribution of load
