A safety factor greater than or equal to 5.0 was used to determine allowable loads . Steel track members not meeting the specification noted must be investigated in accordance with accepted design criteria 2 Allowable values are for fasteners installed in concrete having the designated compressive strength at the time of installation . 3 Spacing and edge distance constraints are as noted in Figure 1 and Figure 3 in the Direct Fastening Product Technical Guide , Vol . 1 , Ed . 24 . 4 Allowable shear load values are for loads applied perpendicular to the edge of the concrete . 5 Multiple fasteners are recommended for any attachment . 6 Minimum edge distance of 3 ” cannot be decreased . Closer edge distances can result in edge breakout failure of the base material during installation . As a result , fasteners are offset from the center line of the track . 7 SSMA track designation for 3-5 / 8 ” track is 362T 150-54 and for 6 ” track is 600T 150-54 . 8 For additional technical data and materials specifications for X-U and X-P fasteners , see X-P & X-U Fasteners Material Specifications ( page 3 ) and X-P & X-U Fasteners Technical Data ( page 4 ) of this Technical Guide 9 For additional technical data and materials specifications for DS fasteners , see New General Application Fasteners .
