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 0.4 mm to 12.7 mm, offering a wide range of possibilities in plastic panel assembly.

Available in Steel or Stainless Steel (A4 / 316) Versions

For standard applications, the nut is available in zinc-plated steel (M4, M5, M6, M8). For composite or corrosion-sensitive environments, the stainless steel 316 version (M5, M6, M8) is recommended.

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.

Specifications
