How important are lock nuts on the rod caps?

The A&I engine rebuild kit came with new bolt and nuts for the rod caps on my perkins ad3.152 I'm rebuilding. The old nuts do have a locking mechanism, but the new nuts from A&I don't...I can finger turn them all the way down...how important is the locking mechanism for the rod nut, or is proper torque good enough?
 
Hi, If your new kit came with new rod bolts and nuts and no locks it has the newer updated hardware. Then the proper torque will be ok.
