SHH Steel Header Hanger


On This Page

The SHH steel header hanger is used to support traditional CFS box headers that are fabricated with top and bottom tracks, as well as large-flange lay-in headers that are common in curtain-wall construction. The connector geometry minimizes drywall buildup, and the screw count has been minimized through extensive testing. A wide array of value-engineered hole patterns are available that will accommodate different load levels while minimizing installed cost.

Key Features

  • The bottom tabs transfer wind load from the horizontal window header to the jamb studs and help support the header assembly during installation.
  • Tabulated loads are based on component assembly testing, which assists to mitigate design risk.
  • The SHH6 is manufactured in steel thicknesses of 54 mil (16 ga.) and 68 mil (14 ga.) that are intended for use with 6"-deep (min.) box headers, and the SHH3 is manufactured from 68 mil (14 ga.) steel and is intended for 3 5/8" or 4"-deep (max.) box headers and large-flange lay-in headers.
  • To enable easier drywall installation, the gusset portion of the SHH is coped to avoid 1 1/2" (max.) track legs.
  • The screw-hole layout at the jamb studs accommodates flange sizes of 1 5/8", 2", 2 1/2", 3" and 3 1/2". This versatility allows the load to be evenly distributed along two lines of fasteners so that each jamb stud carries equal axial load with minimum eccentricity.


  • SHH3 /68 — 68 mil (14 ga.), 40 ksi; SHH6 /54 — 54 mil (16 ga.), 40 ksi; SHH6 /68 — 68 mil (14 ga.), 40 ksi


  • Galvanized (G90)


  • At each connection to a jamb stud, use one SHH connector on each side of the header. A 1/8" (max.) gap is allowed between the end of the header and the face of the jamb stud. Use all specified fasteners.

Ordering Information

  • SHH3/68-KT24, SHH6/54-KT24 and SHH6/68-KT24 are each packaged as boxes of 12 right-handed connectors and 12 left-handed connectors

  1. Allowable loads are for use when utilizing Allowable Stress Design. Contact Simpson Strong-Tie for LRFD loads.
  2. Allowable loads are based on cold-formed steel members with a minimum yield strength, Fy, of 33 ksi and tensile strength, Fu, of 45 ksi for 43 mil (18 ga.) and thinner, and a minimum yield strength of 50 ksi and tensile strength of 65 ksi for 54 mil (16 ga.) and thicker.
  3. Allowable loads may not be increased for wind or seismic load.
  4. Allowable loads for #10 self-drilling screws are based on a minimum nominal shear strength, Pss, of 1,620 lb. and nominal tension strength, Pts, of 2,460 lb.
  5. It is the responsibility of the Designer to select the proper-length fasteners based on installation need. Screw length must ensure fastener extends through the connection a minimum of three exposed threads.
  6. Screws must be located in screw hole locations shown in SHH screw patterns on page 4 of flier F-CF-SHH17 to achieve listed loads.
  7. It is the responsibility of the Designer to verify the adequacy of the stud framing. Allowable loads are based on clips installed an adequate distance away from penetrations, notches, ends of studs and other conditions that may affect the clip performance.
  8. Industry studies show that hardened fasteners can experience performance problems in wet or corrosive environments. Accordingly, use these products in dry and non-corrosive environments only.
  9. Connectors must be installed in pairs. Fasteners listed are number of fasteners for both clips in the connection at one end of header.
  10. Allowable load is total load at one end of header assembly with both clips (left hand and right hand).
