Unlike the standard wall receptacle that needs you to push the plug into the holes of the socket in order to make a connection, twist lock receptacles make use of a twisting method with the plug to create a connection.

However, if you have a 30 amp twist lock plug, you need to upgrade to 10 AWG wire. And for a plug rated for 40 amps and 50 amps, jump to 8 AWG and 6 AWG, respectively. These wire gauge specifications apply to both the conventional and twist lock plugs. It is difficult to wrap thicker wires around terminal screws.
