Expansion rivet nut

Expansion rivet nut
LOADING ZOOM

The blind expansion nut or jack nut for plastics (type “Flower-Nut”) from Juno Industries BV enables fast and reliable creation of an internal thread in plastic sheets and thin panels — without requiring access to both sides of the workpiece. Ideal for industrial applications, machinery, and plastic assembly.

Description

Advantages & Applications

Suitable for Thin Panel Thicknesses


Available for panel thicknesses from 0,4mm up to 9,5mm, offering a wide range of possibilities in plastic panel assembly.

The nut is available in zinc-plated steel (M4, M5, M6, M8) and for composite or corrosion-sensitive environments, the stainless steel 316 version (M5, M6, M8) is recommended that can be applied in thicknesses up to 12,0mm.

Ideal for “Blind” Installation


Thanks to its blind-mounting feature — only one side of the panel needs to be accessible — this nut is perfectly suited for tubes, profiles, or other hard-to-reach structures.

Frequently asked questions about Expansion rivet nut

Which tool do I need for installing the rivet nut?

A standard rivet nut tool or an electric/pneumatic setting gun is sufficient. For smaller applications, a manual tool will do. For installation without any tool, the Rubber-Nut® is an excellent alternative.

Can I use this rivet nut in plastic materials?

Yes, provided that the correct grip range and material are selected. For additional sealing or vibration damping, the Rubber-Nut® is a very good alternative.

 
 

Which blind rivet nut should be used for thicknesses > 5 mm?

For thicker sheets and panels, it is best to use a rubber blind rivet nut, a TC/INT model, or a Flower-Nut. Each has different advantages, and the Flower-Nut is also available in stainless steel 316.
