Expansion rivet nut
Mounting a rivet nut without a tool?
The expansion rivet nut type Flower-Nut allows you to mount a steel zinc plated M4, M5, M6 and M8 innerthread in thin applications of 0,4 up to 9,5mm thick.
Simply screw in the bolt until the Flower-Nut is sufficiently deformed on the thin panel.
The expansion nut is also available with M5, M6 and M8 internal threads in stainless steel316, making it suitable for use in composite materials as well. For those, we advize the use of a tool because of the stifness of the stainless steel 316.
Description
The expansion rivet nut is available in 2 sizes, offering M4, M5 and M6 versions for sheet thicknesses from 0.4 up to 9.5 mm. The 2 M8 sizes cover sheet thicknesses from 0.4 up to 8.0 mm.
The advantage of this blind rivet nut for thick panels and sheets is that no tools are required: simply screw in the bolt and it will deform behind the panel.
The blind rivet nut can also be pre-installed for assembly using a manual tool, an electric blind rivet nut tool, or a pneumatic rivet nut tool, by pulling back the internal thread relative to the collar after placing the nut into the prepared hole in the sheet. Once the blind rivet nut is riveted, the mandrel of the tool must be unscrewed. This way, an internal thread can be created “blindly” in thin sheet, in other words, without accessing both sides of the sheet. This makes it the ideal solution for tubes and profiles.
