Special screws

High-precision CNC screw manufacturing

Standard and special screws manufactured by CNC machining, from technical drawings or according to DIN, ASTM and ISO standards, with certified materials and full traceability.

AREM-CNC manufacturing

Machined screws for demanding industrial applications

At AREM-CNC, we specialise in the manufacture of special screws by machining, designed and produced according to the technical requirements of each project.

Our screws are used in sectors where reliability, mechanical strength and traceability are essential requirements: energy, petrochemical, construction, naval and nuclear industries.
