1 The tabulated allowable load values are for the X-BT-MR and X-BT-GR fasteners only , using a safety factor of 5.0 . Wood or steel members connected to the base material must be investigated in accordance with accepted design criteria . 2 Minimum edge distance and minimum spacing are 3 / 8 " and 5 / 8 ", respectively . 3 Maximum installation torque for the X-BT-MR is 14.8 ft-lb . Maximum installation torque for the X-BT-GR is 14.8 ft-lb when in connection with the X-FCM-R HL and 5.9 ft-lb when in connection with the standard X-FCM-R . 4 Multiple fasteners are recommended for any attachment . 5 Allowable Loads commonly used in North America . Static and seismic allowable loads based on testing and evaluation in accordance with ICC-ES AC70-16 , including Annex A . 6 Allowable shear load requires that the shear is transferred directly to the fastener steel washer at surface . Shear loads shown are not valid for friction as a shear transfer mechanism . |

1 Recommended loads are based on a global safety factor of 2.8 applied to the characteristic resistance for static tension or shear , which are derived from the 5 % fractile of the ultimate load . Recommended moment values are based on a global safety factor of 1.75 . This safety concept is commonly used in regions outside of North America , where design is carried out in accordance with the Eurocode . 2 Multiple fasteners are recommended for any attachment . |

1 Design resistance is based on a safety factor of γM = 2.0 applied to the characteristic resistance for static tension or shear , which is derived from the 5 % fractile of the ultimate load . Moment design resistance values are based on a safety factor of γM = 1.25 . Design resistance should be greater than calculated demand that has been reduced by a partial safety factor . This safety concept is commonly used in regions outside of North America , where design is carried out in accordance with the Eurocode .
2 Multiple fasteners are recommended for any attachment .
