High-Quality Welding Nut with Nylon Locking Feature

The nylon collar insert Ingeniously positioned at the terminus of the nut, the nylon collar insert features an internal diameter (ID) subtly smaller than the major diameter of the screw. Importantly, the screw thread remains untouched by the nylon insert; instead, as tightening pressure is applied, the nylon deforms elastically over the threads. This deformation engenders a locking effect, binding the nut to the screw through friction. This friction is a result of the radial compressive force emerging from the nylon's deformation, ensuring a secure, reliable joint.
