Manufacturing custom threads and mechanical processing of highly customised special parts.
TÜV NORD CERT GmbH
We manufacture your custom-made saw thread lead screws and nuts according to your drawing. Thanks to our innovative and high-quality manufacturing process, micro-pockets are formed on the flank surface, which is ideal for the adhesion of lubricants. As a result, our saw thread spindles have a longer service life and reduced risk of the dreaded stick-slip effect.

Screws with a buttress thread profile are mainly used in vertical lifting applications where the load is firmly supported on the upper flank of the screw thread.
The asymmetrical profile of the buttress thread, makes them suitable for bearing extremely high, single-direction axial loads and their load capacity is far higher than that of common Acme screws or Trapezoidal screws. Therefore buttress threads are commonly used as:
Just give us the specifications you want – that’s really all we need! You can leave the technical conversion of your vision into an actual finished buttress thread to us. Simply send us a technical drawing or rough sketch with some dimensions and we will do the rest.
