Hexagon nuts
Material: Steel 10 | Surface: zinc-plated, thick-film passivated (VZD)

DIN 982 | steel | 10 | zinc-plated, thick-film passivated (VZD) | Cr (VI) - free | metric thread

Note: Similar to ISO 7040 | DIN standard has been withdrawn | modified nut height and wrench width


The hexagon nuts are self-locking nuts with special metal insert. A metal clamping part is fixed in the inner groove. The metal insert has a reliable clamping effect on the full circumference of the thread when attached. It is firmly integrated and cannot be accidentally forgotten. The hexagonal nut can be used multiple times.

advantages:
• Reusable
• Reliable securing by clamping action of the metal insert
