Product range

We offer a wide range of trapezoidal screws with metric thread:

  • Diameters from 16 mm to 120 mm
  • Thread pitch from 4 mm to 14 mm
  • Pitch from 3 to 50 mm, lengths up to 6,2 m
  • Maximum thread length 12 m (according to diameter and precision class)

Precision classes:

Thread shafts and nuts are manufactured in three precision classes:

  • 1 – fine – ground profile of the shaft thread (used in thread grinding machines, CNC boring machines and other machines with higher accuracy),
  • 2 – intermediate (used in cutting machines, lathes, milling machines, horizontal boring machines),
  • 3 – rough (used in machine tools without any special requests regarding accuracy).

The precision of the thread is determined by:

  • the system of thread tolerances,
  • deviation of thread pitch,
  • accuracy of shape and position of the thread,
  • thread surface roughness.
