Our specialization in processing roll threading has allowed us to continually increase our skills over the years along with the potential for supplying screws and nuts machined to design in different sectors.
In nut-screw systems for manoeuvring or movement, we can offer:
- ISO 2901 trapezoidal profile screws with ends machined to design and related nuts
- Trapezoidal profile multi-start screws with ends machined to design and related nuts
- Screws with thread profile optimized to increase performance, with ends machined to design and related nuts
- Multi-start high-helix screws with ends machined to design and related nuts
- Screws with profile for coupling ball recirculation nuts, with ends machined to design
- Screws with through-hole for lightening or pull-out systems
- Pre-assembled nut-screw units
The evaluation of material variants, thread direction, number of starts, and conventional or particular machining are our strong point for quick and competent feedback.
