HDUE Heavy Duty Holdown
Description

Designed as the direct replacement for our industry-leading HDU, the new HDUE closely matches its predecessor's overall physical dimensions and capacities. The HDUE provides exceptional overturning resistance for critical lateral force-resisting applications, including shear walls and braced wall panels in timber construction.

This innovative design delivers higher loads and faster installation. It is the ideal solution for shear walls in timber structures demanding superior capacities and enhanced stiffness.

Key Features
  • Pre-deflected seat and tension screws greatly improves stiffness and reduce 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 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 studs splitting.
  • Optimized screw patterns reduce splitting at the stud ends and maximize individual fastener capacity.
  • Installs with Strong‑Drive SDS Heavy‑Duty Connector screws.
Scope of Use
  • Designed for use in shearwalls and braced wall panels, as well as other lateral force resisting applications in residential and commercial timber construction.
  • HDUE is suited for retrofit or new construction projects.
Limitations on Use
  • Check the Installation Guide from the product flyer
  • The HDUE requires no additional washer
  • The nut should be tightened another 1/3 to 1/2 a turn more with a hand wrench.
Statement of Building Code Compliance
  • HDUE Heavy Duty Holdown is compliant with NZS 3604:2011
