Manufacturing of Standard and Custom Nuts
At AREM-CNC, we specialize in the precision machining of special nuts, designed to meet the highest requirements for strength, precision, and reliability.
Our production is carried out according to DIN, ISO, or customer drawings, ensuring compatibility with high-performance fastening systems in industrial, energy, mechanical, and structural sectors.
Each nut is machined using high-precision CNC equipment, guaranteeing tight tolerances, dimensional repeatability, and a perfectly calibrated thread for the intended application.
We offer a wide range of CNC-machined nuts, both standard and custom-made:
All our nuts are manufactured in accordance with DIN 934, 985, 982, 6923, 1587, 928, 929, among others.
