The buttress thread form is designed to handle axial thrust applied principally in one direction. The load-bearing thread face is perpendicular or at a slight slant (usually no greater than 7°) to the screw axis. [3] The trailing face is slanted, often at 45°. The resulting thread form has the same low friction properties as a square thread ...

Buttress roots vary greatly in size from barely discernable to many square yards (square meters) of surface. The largest for which there is photographic evidence is a Moreton Bay Fig ( Ficus macrophylla ) at Fig Tree Pocket (an outlying district of Brisbane , Queensland ) which was photographed in 1866 with an adult man.
Pinnacles, studded with crockets, on King's College Chapel, Cambridge.
