INSTALLATION:

  • Install the holdowns using anchor bolts or alternate anchorage calculated to resist the tension load for your specific application. 
  • Use steel nylon locking nuts or thread adhesive to minimize the chance of nut spin. Anchor bolt washer is not required.
  • For the bolted holdowns, secure the CD holdown to the steel framing member with 3/4" and 1/2" diameter bolts in the prepunched holes per the design load table to achieve listed capacities. Field drill holes in the framing member as required to accomodate the required bolts.
  • Boundary members (back-to-back studs) shall be designed by a qualified professional. To tie back-to-back stud members together, the Designer must determine the fasteners required to bind members to act as one unit.
  • CD holdowns can be welded per Designer's recommendation and specification.
  • Welding procedures shall be qualified as specified in AWS D1.3.
  • Welded connections used for cold-formed steel structural members in which the thickness of the thinnest connected part is 0.18 inch or less shall comply to AISI S100-2012 specification Section E2.
