After the city and the Amt Hemer were granted coat of arms in 1936, all of the remaining municipalities in the Amt received coat of arms until 1939. The municipalities which were no longer independent at that time did not receive coat of arms - Brockhausen was incorporated into Deilinghofen; Landhausen, Sundwig and Westig were incorporated into Hemer; Calle was split between Iserlohn and Hemer. Lössel had left the Amt in 1920 already, and thus didn't receive a coat of arms at that time either.
All of the coat of arms expired when the Amt was dissolved in 1975, only the coat of arms of Evingsen expired already in 1969 when Evingsen was incorporated into Altena. Even though the coat of arms are no longer used officially, the communities in the former municipalities continue to use them unofficially. All coat of arms display three wolf hooks as the symbol of the Brabeck family. The common symbol was chosen to show the membership in the Amt.
The coat of arms show a beech tree, separated with a wavy line from the bottom. The beech tree is the symbol of the noble family von Schüngel, who former lived in the municipality.
