The beech leaves in the arms refer to the geographical location in the High Spessart and are canting for the community's name (Buchen is German for beeches). The wavy fess (horizontal band) symbolizes the community's location in the Elsava valley. The combination of the wavy fess and the cogwheel refers to the hammerworks that was running in the 18th and 19th centuries in the outlying centre of Höllhammer. The tinctures gules and argent (red and silver) are those also seen in the Electoral Mainz coat of arms, Mainz having held the local lordship until 1803. The Electoral Mainz Amt in the community comprised eight places and gave it a certain autonomy.
