MODULAR FIXTURES ALUMINIUM ALLOY
Modular fixtures gathered steel, stainless steel or light alloy channel in which self-locking nuts are trapped, or screws positioned at predefined distances. In the case of screws, the indeserability of the fasteners will be achieved by the use of self-locking nuts.
Self-locking nuts have a square or rectangular part that is immobilized in position in the slide and a turret with two slots. The principle of self-locking of these nuts is to compress the flank of the thread of the male element on two sectors located in different planes and offset by 180 °.
This principle is obtained by making two calibrated slots in the upper turret of the nut which are then crushed under a specific load to obtain a permanent deformation of the two slots (elastoplastic deformation).
During the assembly, the deformed slots in the upper turret of these nuts are pushed by the thread of the male element. This thrust generates pressure on the flank of the thread of the male element on two sectors creating a constant braking torque (called self-locking). This self-locking torque is independent of the tightening torque applied when tightening these nuts.
