Application and Function
Suitable for: Soft materials, especially aluminum, plastic and magnesium
Pilot hole preparation: Round pre-drilled or punched pilot hole
Preferred use: Especially for one-sided joining positions e.g. difficult-to-reach positions, parts with undercut or overlap, closed profiles
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
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.
