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. 

Features

  • Replaces traditional labor intensive installation methods
  • Pre-punched guide holes for quick attachment
  • Ledger tabs to hold header during installation
  • Designed for multiple stud sizes and jamb configurations

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

  1. The allowable loads are based on the steel properties of the members being connected, per NASPEC with 2004 supplements.
  2. The nominal strength of the screw must be at least 3.75 times the allowable loads.
  3. Values include a 3.0 factor of safety.
  4. Penetration of screws through joined materials should not be less than 3 exposed threads. Screws should be installed and tightened in accordance with the screw manufacturer’s recommendations.
  5. Allowable loads indicated on the table(s) are for force in single direction only. If more than one force is applied to the connection, the designer shall provide the combined forces check as required by NASPEC with 2004 supplements.
  6. Allowable loads do not include prying or plate bending.
