Secure Blind Fastening. Built for High-Stress Joints.
When working with thin sheet metal, hollow panels, or tight spaces where you cannot access the back, standard nuts and bolts strip or fail. The Button Rivet Locking Nuts Set expands into a 4-petal anchor for unbreakable, vibration-resistant threads.
Watch It Expand & Lock in Seconds
As the screw tightens, the slotted body collapses outward into four wide petals, clamping the backside of the material with relentless grip.
Tired of Stripped Threads & Loose Fasteners?
Sheet metal under 2mm is notoriously impossible to tap reliable threads into. Self-tapping screws vibrate loose within weeks. These petal rivet nuts create permanent, high-strength machine threads that withstand intense shock and repeated assembly.
Zinc-Plated Shielding. Zero Rust, Indoors or Out.
Forged from premium structural carbon steel and treated with a protective electro-zinc coating. Built to withstand road salt, humid marine air, vehicle wash chemicals, and daily atmospheric moisture without seizing or corroding.
🌧️ Weather Resistant
Shields raw steel against rust and oxidation in open outdoor applications.
⚙️ Smooth Screw Engagement
Precision-cut threads resist galling and binding when torqued down tight.

Frequently Asked Questions
Do I need access to the back of the panel to install these?
No! That is the core advantage of petal rivet nuts. They are "blind" fasteners installed 100% from the front side. As the tool pulls the mandrel, the petals expand behind the sheet automatically.
Can these be installed in plastic or fiberglass without cracking?
Yes. The four-petal expansion spreads the clamping load over a significantly larger surface area compared to standard knurled rivet nuts, preventing stress cracking in brittle composites and soft plastics.
What tool is required to install them?
They can be installed using any standard manual rivet nut tool, cordless rivet gun adapter, or even a simple DIY bolt-and-nut wrench spacer method in emergency field repairs.
Will these spin in the hole when I tighten a bolt?
No. Once the four petals flare out and clamp tightly against the rear surface, the wide footprint prevents the body from rotating or backing out during bolt torquing.
