HG – Secure Plate Header Gusset

SCAFCO’s secure plate header gusset (HG) is designed to provide a stiffened attachment of two individual members. Its unique design transfers the vertical load through a rigid connection that is far superior than traditional methods of construction.

The header gusset contributes to the headers web crippling and shear capacity, allowing the header to withstand larger loads and decrease the chance of possible failure from job site connections.

Screw shear values are based on the SSMA Screw Table with the following notes:

  1. Allowable loads have not been increased for wind, seismic activity, or other factors.
  2. Screw spacing and edge distance shall not be less than 3 x d (d=nominal screw diameter).
  3. The allowable loads are based on the steel properties of the members being connected, per AISI Section E4.
  4. When connecting materials of different thicknesses or tensile strength (Fu), the lowest applicable values should be used.
  5. Attachment from the clip to the structural to be designed by others.
  6. Values include a 3.0 factor of safety.
  7. Applied loads may be multiplied by 0.75 for seismic or wind loading, per AISI Section A5.1.3
  8. Penetration of screws through joined materials should not be less than three exposed threads. Install and tighten screws in accordance with the screw manufacturer’s recommendations.
