S/PHD Holdowns
The S/PHD holdowns are high performance ductile holdowns used for
providing a tension connection between CFS framing members and the
foundation or other structural members. The pre-deected design keeps
deection low. The S/PHD holdowns attach with #14 self-drilling screws
making installation an ease, saving time and labor.
Materials: S/PHD4, S/PHD6 – 14 gauge; S/PHD9 – 12 gauge
Finish: G90 galvanizing
Codes: IBC
Installation:
• Use all specied fasteners.
• Place the S/PHD over the anchor bolt. No washer is required.
• Install with standard #14 self-drilling (tapping) screws to fasten to
CFS framing members.
• Tighten anchor bolt nuts nger tight to base plus 1/3 to 1/2 additional
turns with a wrench.
• S/PHD Holdowns installed elevated more than 4" off the base track
may have higher deection values.
• The design engineer may specify any alternate anchorage calculated
to resist the tension load for a specic application. Anchor rod exposure
length should take the bearing plate height of 1-5/8" into account,
anchor bolt thread should visibly extend above nut.
• The built up studs shall be designed to act as a single unit. Holdown
specied shall not be considered to attach multiple CFS
members together.
• For anchorage options see MiTek’s STB/ STBL Anchor Bolt series or
ATR threaded rod series products epoxied into place at required depth.

1) The designer must specify the anchor bolt type, length and embedment.
2) Deflections are derived from static, monotonic load tests of device connected to a 2-ply cold-formed steel stud
and include fastener slip, holdown elongation and anchor bolt elongation (L = 4").
3) #14 screws are ITW Buildex 1/4-14 HWH Teks Structural Fasteners with a nominal diameter of 0.250". Self-drilling tapping screws
with equivalent physical and strength properties may be used.
4) The designer must specify the metal stud size and mil thickness.
