Buttress thread

Buttress threads are used as movement or drive threads. The main feature of these threads is that the profile is asymmetrical. In this way, an enormous force can be applied in one load direction.

Buttress threads are manufactured according to the standards DIN 513, DIN 514, DIN 20401, DIN 2781 and DIN 6063. The flank angle is between 30 and 45 degrees.

Buttress threads often suffer from greater wear due to their design, as the edges are very filigree. This thread form is self-locking.

We supply buttress nuts in various diameters and pitches. The threaded nuts also differ in terms of material, direction of rotation and their geometry.
