ICC-ES AC259 – Acceptance Criteria for Power-actuated Fasteners Used for Attaching Gypsum Board Materials to Cold-formed Steel Wall Framing


The AC259 provides guidelines and requirements for manufacturers to demonstrate that their power-actuated fasteners are suitable for the intended purpose. This includes determining:

  • Performance: the fastener’s ability to securely attach the gypsum board to the steel framing, withstanding forces like pull-out, shear, and other relevant stresses.
  • Suitability: assessing whether the fasteners are compatible with both gypsum board and cold-formed steel. This considers factors like corrosion resistance and potential adverse reactions.
  • Compliance: ensuring fasteners meet industry standards and building codes.
