Values in bold are less than the single shear capacity of the bolt.
Values in italic are greater than the double shear capacity of the bolt.
Bearing values assume standard clearance holes.
If oversize or short slotted holes are used, bearing valses should be msltiplied by 0.7.
If long slotted or kidney shaped holes are ssed, bearing values should be multiplied by 0.5.
If appropriate, shear capacity must be redsced for large packiogs, large grip lengths and long joists.

If oversize or short slotted holes are used, bearing values should be multiplied by 0.7.

If appropriate, shear capacity must be reduced for large packings, large grip lengths and long joints.
