Petal Expansion Rivet Nut Set
for Reliable Panel Fastening
Create a reusable threaded fixing point in compatible thin or hollow materials with expanding metal anchor bodies and matching screws.
A Petal-Shaped Anchor That Grips from the Back
During installation, the slotted metal body compresses and expands behind a compatible panel. This creates a wider rear contact area while the front flange remains seated against the surface.
Thickened Head, Expanding Body & Steel Construction
The flanged head supports the front surface, the slotted body expands behind the material, and the metal construction provides dependable strength for suitable non-critical fastening jobs.
Useful Where the Back of the Panel Is Hard to Reach
Suitable applications may include thin sheet metal, selected wood panels, hollow boards and compatible ceiling panels. Always confirm material thickness, hole diameter and load requirements before installation.
Choose M4, M5 or M6 for the Job
The assortment covers three common sizes for different hole diameters, fastener needs and compatible panel thicknesses.

Four-Step Installation
For Panels, Furniture Hardware & Sheet-Metal Projects
Useful for compatible equipment covers, automotive interior or body panels, furniture brackets, cabinet hardware and general thin-panel fixing where a threaded anchor is appropriate.
Durable Metal Fasteners for Everyday Workshop Use
The carbon steel construction provides strength, while the zinc-plated finish helps improve resistance to everyday oxidation and corrosion. Keep dry when possible and select a more protective grade for severe exposure.
Ten Pieces of Each Size
A practical mixed set for occasional repairs, installations and workshop storage.
Thirty Pieces of Each Size
A larger supply for frequent workshop projects, maintenance jobs and multi-point installations.

⚠️ Installation & Load Notes
- Confirm the anchor size, hole diameter, grip range and panel thickness before drilling.
- Use a compatible setting tool and do not overtighten, which may damage the panel or threads.
- Load capacity depends on substrate material, thickness, edge distance, installation quality and fastener size.
- Zinc plating improves corrosion resistance but does not make the fastener completely rustproof.
- Do not use for overhead, structural, fall-protection or other safety-critical loads without engineering approval.
