1 The tabulated ultimate loads were developed from testing the low-velocity fasteners with 16 gauge ( Fy ≥ 33 ksi ) steel track . 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 Figures 1-3 on previous page 42 . 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 Section 3.2.6.2 and 3.2.6.3 of this Technical Guide 9 For additional technical data and materials specifications for DS fasteners , see section 3.2.5 .
