Process for standard applications

AUTORIV blind rivet nut stud fastener inquiry process

Performance

Push-out force  - Larger head diameter vs. countersunk head
For high push-out forces, blind rivet nuts and studs with larger head diameters and head heights are recommended. Blind rivet fasteners with a small countersunk head have only low push-out forces. However, their advantage is that the created connection is almost flush with the sheet metal surface. The countersunk head is almost completely embedded into the sheet, so there is only a minor excess of the head above the sheet surface.
If near flushness is required, blind rivet fasteners with a countersunk head should be considered. Other than that, a larger head is recommended due to the higher push-out forces.

Spin-out resistance - Knurled grip range
For blind rivet fasteners with round body, the knurled grip range provides increased spin-out resistance in softer materials.
