That's one of the reason pics are so great.
Locking lugs are what keep the bolt locked to the receiver when firing. When you raise the bolt handle, the lugs are being disengaged from the receiver so that the bolt can be moved to the rear. Without the lugs the bolt would be blown into the shooters face when the rifle was fired.
At the front of the bolt, on the sides, are either two large lumps of steel or nine smaller lumps. How the bolt is designed, including the lugs, help to determine the manufacture of the action.
