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:

• pitches up to 6 x diameter
• spindle length up to 6 m
• spindle diameter from 2 to 160 mm
• high-helix thread profiles
• ball screw thread profiles
• all standard profiles (M, Tr, UNC, UNF, UNEF, Whitworth)
• multiple start threads including left-hand/right-hand threads
• special profiles
• worm gears (quality and price advantages
• serrations and knurlings

Quality Management ISO 9001:2000

What materials are suitable?
– all metals that feature an extension of at least 6 % and do not exceed a tensile strength of 1300 N/mm2
– high-alloy, corrosion and acid-resistant steel
– special aluminium alloys
– riveting-quality brass
– copper alloys
– threads can be rolled on hollow bodies and tubes only if wall thickness is sufficient; this wall thickness depends upon the type and depth of intended ofile as well as material used. Please call or write for more assistance.

What materials are not suitable?
– extremely brittle material such as Ms58, cast iron, etc.
– extremely soft materials such as lead
– synthetics

We look forward to your challenge!
