Improve Rotational Torque of Clinch Nuts

Improve Rotational Torque of Clinch Nuts

After clinched into sheet metal, low rotational torque makes clinch nuts spin together with bolts and cause loose connection. We improve anti-torsion performance via overall process upgrading.

Uniform carbon steel and stainless steel blanks guarantee stable base performance. Precision rolled inner threads bring steady meshing friction. Redesigned barbed claws bite tightly into sheet to avoid circumferential rotation. Proper heat treatment balances hardness and toughness to prevent torque drop from deformation. Standard clinching parameter and batch torque test keep consistent product performance.

Optimized clinch nuts are widely used in equipment cabinet, new energy housing and auto sheet metal assembly.
