The arms were officially granted on January 6, 1961. The bell is the symbol of St. Anthony, patron saint of the local church. The colours blue and gold are also the colours of the Order of St. Anthony. The lower half shows the black bars of the Lords of Diest, who ruled the village and estate of Hamb in the 18th century.
