General Information
Blind rivet studs, also known as blind rivet screws or blind rivet bolts, are used to insert a thread into thin sheet metal or plastic. In contrast to a blind rivet nut, which provides an internal thread for fastening screws, a blind rivet stud itself has an external thread that can be used for direct fastening.
Blind rivet studs offer an efficient way of fastening components, especially when there is no access to the back side of the material.
The blind rivet stud is threaded onto an internal thread before the setting process and inserted into the prepared pilot hole in the component. It is subjected to a pulling force via the pulling thread, causing it to deform on the back side of the sheet metal and form a rivet bulge.

Application and Function
Suitable for sheet metal: Suitable for all material variants
Pilot hole preparation: Hex-shaped 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 – Hexagonal body vs. round body design: In comparison to blind rivet studs with a round body, the hexagonal shank provides significantly higher spin-out resistance, especially in harder sheet metal.
However, the requirement for using blind rivet fasteners with a hex body is that a hex-shaped pilot hole can be punched into the component. For heavy-duty applications, fullhex blind rivet studs are recommended.
Push-out force - Larger head diameter vs. countersunk head: For high push-out forces, blind rivet 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.
