Clamping nut self-locking

Material:

• clamping nut: heat-treated steel, blackened.

Characteristics:

• self-locking;
• easy installation and dismantling;
• when tightening the clamping nut using a face pin wrench, the two conical surfaces move against each other. As a result, the slotted inner ring narrows like a collet. The nut clamps itself on the flanks of the thread, that they do not detach even with opposite axis rotation.
