Values in bold are less than the single shear capacity of the bolt.
Values is if a/ic are greater than the doable shear capacity of the bolt.
Bearing values assume standard clearance holes.
If oversize or short slotted ho/es are used, bearing values should be multiplied by 0.7.
If long slotted or kidney shaped holes are used, bearing values should be multiplied by 0.5.
If appropriate, shear capacity mast be reduced for large packings, large grip lengths and long joints.
