Manufacturing of thread forming screws for plastic and aluminium
BM-Boulonnerie manufactures thread forming screws or self-tapping screws with special threads for plastic materials and aluminium from plans.
Threads at 30°:
- symmetrical or asymmetrical,
- Flat or conical bottom and
- more special threads at our customers’ request
are made by material deformation, which improves the resistance and friction of the threads during their installation. Several head and footprint variants are possible depending on the function of the screw. Thermal and surface treatments are carried out by our specialized subcontractors.
BM Boulonnerie manufactures thread forming screws for plastics and aluminium to customer plans and provides know-how.
