OUTSOURCING PROCESS

COLD FORMING -> Manufacturing of special screws and nuts in economic batches – max. diam. 30 mm

HOT FORMING -> Manufacturing of screws and nuts – over diam. 30 mm for standard material or for the production of small batches of special diameters or materials.

FORGING UP TO 130 KGS -> Production of “BONNET BOLTS” or similar parts.

ROLLING -> Manufacturing of threaded rods and stud bolts (both fully threaded and threaded to the ends)
