Tech Note 562-22: Powder-Actuated Fasteners in Cold-Formed Steel Construction


Summary: Power-actuated fasteners (PAF’s) are industry standard for attachment of cold-formed steel (CFS) steel framing members, usually track, to concrete, CMU or steel structural elements. “Power-actuated” is the broad category used to refer to fasteners which are driven directly through the CFS and into the substrate, using a powder, gas, compressed air or electro-mechanically driven tool. Efficient installation of framing systems is greatly enhanced by the use of PAF’s. For CFS-to-steel applications, the specification AISI S100 addresses all relevant limit states with equations and safety/ resistance factors. For CFS-to-concrete, limited guidance is provided but not all limit states are covered. This technical note will provide design guidance based on AISI S100, as well as installation and good detailing practice.

This Technical Note updates and replaces CFSEI Technical Note 562
