size of hole = nominal diameter of fastener – clearances

size of hole = nominal diameter of fastener x clearances

size of hole = nominal diameter of fastener / clearances

size of hole = nominal diameter of fastener + clearances

Shear Connection

Slip Resistance Connection Only

Bearing Type Connection Only

Both Slip Resistance and Bearing Type Connection

Bolts are subjected to shearing and bearing stresses

High strength fatigue

Low static strength

Joints are not rigid
