Plug SIG...AR-N with snap-in lock and internal thread connection

MC-Plugs type SIG...AR-N are suitable for all sockets with a snap-in lock and with the corresponding nominal diameter. SIG...AR-N plugs have a thread connection to secure onto threaded bolts. To lock, the plug is inserted into the corresponding socket until the snap-in engages. (Check the snap-in operation by trying to pull the plug out of the socket.) To release, first insert the plug further in and then pull out.
