EXPANDABLE PETAL NUTS · FOR THIN PANELS

Create a Secure Thread Where Standard Nuts Cannot Reach

The petal-style body expands behind thin material to form a wider gripping surface—ideal for repair, mounting and assembly jobs with limited rear access.

The 90-piece savings percentage compares its current price with three 30-piece sets and is rounded to the nearest whole percent.

How the petal-locking design works

As the fastener is compressed, the slotted sleeve opens into petal-like legs behind the panel. Tightening the screw then pulls the expanded body firmly against the material, creating a reusable threaded mounting point.

A practical fix for hard-to-reach fastening points

  • Blind-side installation: useful when you cannot easily hold a standard nut behind the material.
  • Firm panel support: the expanded petals spread the load across a wider rear area.
  • Reusable threaded point: once installed, the matching screw can be removed and refitted for service or adjustment.
  • Choose your setup: select fasteners only, or start with the installation-tool bundle.
