A Deckenanker is a long gewindestang that connects a Stemkesseldecke to a Firebooksdecke

A Deckenanker is a long gewindestang that connects a stemkesseldecke to a firebooksdecke. Without this attachment, a stemkesseldecke cannot withstand the 180-ton load. Deckenankers are made of ST 52.3 with an attest, and they receive fortlaufend M 28 X 2.5 in both deck areas. They are also mounted on a Sechskantmutter and are dampfdicht.
