Powder-actuated (also referred to as low velocity or powder-driven) fasteners are commonly used to attach cold-formed steel framing members, usually a track, to a concrete or structural support. Although commonly used, their behavior is less well understood than other fasteners such as screws, bolts and welds. The AISI Cold-Formed Steel Design Manual does not explicitly address powder actuated fasteners. Several guidelines have been put forth in the past but these do not reflect the latest tested data on powder-actuated fasteners. This technical note will explain installation, behavior and good detailing practices. Design values for powder actuated fasteners are also provided.
