Quick question, what size are throttle body bolts?

Im getting ready to go to the store and buy some bolts to attach tb and egr spacer to intake. what bolts do i need? im gonna use bolts instead of studs. anyone know the length and size off hand? also, i need to pick up some bolts to attach the throttle cable bracket to the egr spacer, this is a different size, anyone know the size?
 
Try some 5/16" threaded rod & cut to fit. The stock bolts are a low torque item since they screw into the soft aluminum upper manifold casting.
