Expandable Petal Nuts for Thin Panels – 30/90 Pcs or Tool Kit
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.
A smart stock-up choice for repeat repairs, workshop use and larger projects—at the lowest current cost per fastener.
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.
Expanded petal support
For sheets and hollow sections
Built for dependable fastening
Helps resist corrosion
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.
Made for repairs, mounting and assembly
