Thread rolling
State-of-the-art production methods, extensive
product expertise and access to more than
1000 machine tools, enable us to meet each
and every demand for rolled threads – however exotic they may be:
What is thread rolling?
What materials are suitable?
Thread rolling (often also referred to as thread
– all metals that feature an extension of at least
milling) is the cold forming of the surface of
6% and do not exceed a tensile strength
round workpieces. The thread form is pro-
of 1300 N/mm2
duced by causing a radial dynamic force to
–high-alloy, corrosion and acid-resistant
be exerted between the two rotating rolling

dies that form the workpiece. As the roll die

material in cold state is pressed all the way

–pitches up to 6 x diameter
– threads can be rolled on hollow bodies and

UN thread profile
Basic profile corresponds to basic metric profile except that
diameter and pitch are in inch.
UN = thread with constant pitch
UNC = coarse thread
UNF = fine thread
UNEF= extra-fine thread
UNJF = thread with enlarged root radius (aviation application)
