A fastener driver tool fastener load system includes a fastener driving tool having a housing including a magazine with a fastener entry end, an opposite shear block end, and a fastener track defined between the ends. A tensioner is mounted to the housing and includes a driven roller. A plurality of fastener strips is disposed linearly in end-to-end fashion and each strip is secured to each other by at least one fastening tape having a free end connected to the driven roller. The tensioner is constructed and arranged for creating a biasing force for urging the fastener strips toward the shear block end.
