π© Heavy-Duty Carbon Steel Rivet Nut Assortment Kit (M4/M5/M6)
Create Reliable Threads in Thin & Hollow Panels
Turn compatible panel openings into reusable threaded fixing points with expanding metal anchor bodies and matching screws.
Need a Threaded Fixing Point Where the Back Is Hard to Reach?
Ordinary nuts can be difficult or impossible to hold behind a closed or hollow panel. During setting, the slotted body compresses into petal-shaped sections that spread behind the material while the front flange stays seated at the surface.
Always match the anchor size, hole diameter, grip range, panel thickness, and load requirements to the job before installation.
Thickened Head, Expanding Body & Steel Construction
Thickened Flange
The front head seats against the panel surface to support the fixing point.
Petal Expansion Body
Slotted sides expand behind the panel to create a broader rear grip area.
Carbon Steel Body
Metal construction provides dependable strength for suitable fastening jobs.
Useful When Rear-Side Access Is Limited
Suitable applications may include compatible thin sheet metal, selected wood panels, hollow boards, and ceiling panels where a threaded anchor is appropriate.
Thin Sheet Metal
Create a reusable thread in suitably sized thin metal panels.
Selected Wood Panels
Use only after confirming thickness, hole size, and load suitability.
Hollow Boards
The expanding rear shape is designed for compatible hollow-panel work.
Choose M4, M5 or M6 for the Job
The assortment covers three commonly used sizes for different holes, fastener requirements, and compatible panel thicknesses.
Total: 20 mm
Total: 25 mm
Total: 25 mm
Four-Step Installation

- Carbon steel anchor construction
- Zinc-plated protective finish
- Matching screws included according to the selected set
- Keep dry when possible for better long-term condition
- Select a more protective fastener grade for severe exposure
30-Piece or 90-Piece Mixed Assortment
Choose the compact set for occasional repairs or the larger assortment for frequent workshop use and multi-point installations.
π¦ 30-Piece Set
Ten pieces of each size for repairs, installations, and workshop storage.
π§° 90-Piece Set
Thirty pieces of each size for frequent projects and larger installations.
Check Compatibility Before You Drill
- Confirm anchor size, hole diameter, grip range, and panel thickness.
- Use a compatible setting tool and avoid overtightening.
- Load capacity depends on the substrate, 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.
