DIN 6927 | steel | 8 | zinc-plated | Cr(VI) - free | metric thread
Note:The hexagon nuts are self-locking nuts with metal insert and flange. The flange increases the contact area on the component and additionally protects the surface. An annular metal clamp is fixed in the inner groove. The metal insert has a reliable clamping effect on the full circumference of the thread. It is firmly integrated and cannot be forgotten by mistake. The hexagon nut can be used several times

advantages:
• Multiple reusable
• Reliable securing by clamping effect of the metal insert
• Protects the component surface without washers or spring rings
