Manufacturing of Standard and Custom Screws
At AREM-CNC, we specialize in the manufacturing of special screws through precision machining, designed and produced according to drawings or under DIN, ASTM, or ISO standards. We manufacture custom parts with the highest precision, tailored to the technical requirements of each industrial project.
Our machined screws are used in sectors such as energy, petrochemical, construction, marine, and nuclear industries, where reliability, mechanical strength, and full traceability are essential requirements.
We offer a wide range of CNC-machined screws, both standard and custom-made:
In addition, we develop custom screws based on technical drawings, combining non-standard geometries, threads, and materials, with tight tolerances and tailored finishes.
Surface Treatments
To improve the durability and performance of each pin, we offer various surface treatments:
White zinc plating 5–7 microns
Yellow dehydrogenated zinc plating 12 microns
Hot-dip galvanizing HDG A 153
Mechanical zinc plating
Geomet 321
Silver plating
Electroless nickel plating
Xylan/Xylar 1070–1424
Takecoat 1000
