An out-of-plane load applied to a bracket will cause a simultaneous tensile and shear load to be applied to the bolts.
The following equations will help size fasteners for respective load cases.
Minimum edge distance for bolt holes should be 1.25D minimum
Tensile force in each bolt
Increasing Lx or decreasing Lz will result in a lower stress through the bolts
Shear force in each bolt
Tensile stress in each bolt
A_s = stress area for bolt size
Shear stress in each bolt
A_s = stress area for bolt size
Values of stress area for specific bolt sizes can be found on our Sizing Fasteners guide
