must be investigated in accordance with accepted design criteria . 2 Low-velocity fasteners shall be driven to where the point of the fastener penetrates through the steel base material , except as noted . 3 Multiple fasteners are recommended for increased reliability . 4 The minimum edge distance for fastening into steel is 1 / 2 ". Minimum spacing for fastening into steel without reduction in performance is 1 ". 5 Noted tabulated allowable load values are based upon minimum point penetration of 1 / 2 " into the steel . If 1 / 2 " point penetration into the steel is not achieved , but a point penetration of at least 3 / 8 " is obtained , the tabulated
shear load should be reduced by 8 percent . 6 Noted tabulated allowable load values are based upon minimum point penetration into the steel of 15 / 32 ". 7 Noted tabulated allowable load values are based upon a minimum point penetration into the steel of 1 / 2 ".

1 Testing based on deflection slip clips obtained in February 2007 . Subsequent changes by the manufacturer to the deflection slip clip design may affect load values . 2 Allowable load values are for fasteners installed in concrete having the designated compressive strength at the time of installation . 3 Allowable load values are based off of the fixtures tested . Other members connected to the deflection slip clips must be investigated in accordance with accepted design criteria . 4 Spacing of fasteners depends on the design of each deflection slip clip . Fasteners should be installed through the pre-assigned locations in the deflection slip clip . 5 For base material thickness requirements , reference Fastener Spacing , Edge Distance and Base Material Thickness Requirements for Steel in the Direct Fastening Product Technical Guide , Vol . 1 , Ed . 24 . 6 Allowable values are for loads applied perpendicular to the edge of the concrete . 7 Multiple fasteners are recommended for any attachment . 8 Verticlip is a registered trademark of The Steel Network , Inc .
