The hexagon nuts with clamping part are self-locking nuts with plastic insert. You do not need to store and assemble additional elements such as washers or spring washers. On one of the two end faces, a polyamide ring-shaped clamping part is firmly attached and cannot be accidentally forgotten. The plastic insert has a reliable clamping effect when fastening the nut. The multiple use of the hexagonal nut is not intended.

• Reliable securing by clamping action of the polyamide insert
• Firmly integrated clamping part
