How to test the strength of rivet nuts

1. Screw the rivet nut into the thread core, but ensure that the applied load lasts for 15 seconds. At this time, if the strength is good, there will be no fracture.

2. Screw the rivet nut into the threaded mandrel to apply the load until it breaks, and the break should not occur at the intersection of the head and the cylindrical part.

3. The riveting nut is riveted on the riveting plate, and the test bolt is screwed into the test bolt without any lubrication. At this time, start to apply pressure until the rivet nut cracks or breaks. During the experiment, the torque measurement error of the tool cannot be greater than the rated torque.

4. Rive the rivet nut to the rivet plate and tighten the test bolt without any lubrication, apply torque until the relative rotation occurs between the rivet nut and the rivet plate, the torque measurement error of the torque testing machine or tool used in the test should not exceed the quota h and d0 provisions.
