Trapezoidal-threaded spindles (RATS, RPTS)

The rolled NEFF trapezoidal threads are characterized by a high constant precision, due to production in a restricted tolerance zone.

Material standard is 1.0401/C15. We also offer an extensive program of trapezoidal threads from rustproof material (1.4305/X8CrNiS18-9), RATS.
