Hexagon head bolts DIN 931 in brass CU2/CU3 combine strength, precision, and corrosion resistance for mechanical, electrical, and decorative assemblies. Produced in compliance with DIN 931, ISO 4014, ASME B18.2.3.1M, NEN 1555, and NF E25-112 standards, they feature a durable hexagon head that enables secure tightening with standard tools. The partially threaded shank provides strong clamping capability while maintaining accurate alignment in bolted joints.
Material and Properties
Manufactured from brass CU2/CU3, these bolts offer excellent resistance to moisture, steam, and many industrial chemicals. The alloy provides superior machinability and is naturally non-magnetic and non-sparking, which makes it particularly suited for use in electrical and marine environments. Its attractive surface finish and resistance to tarnish also make it appropriate for visible or decorative connections requiring both function and visual appeal.
Applications and Performance
These hexagon head bolts are designed for right-hand metric threads, ensuring full compatibility with standard nuts and tapped holes. Their combination of corrosion resistance, conductivity, and reliability makes them ideal for electrical installations, marine fittings, and general industrial applications where durability and appearance are equally important.
