Threaded petal nuts are fasteners specially designed for securing thin‑wall sheets. Their unique petal‑shaped structure expands automatically under force to deliver a firm hold, making them widely used for thin sheets, hollow tubes and similar applications.
Reliable Material
The expansion screws and petal nuts are made of high‑quality carbon steel with a zinc‑plated finish for rust and corrosion resistance, ideal for humid or mildly acidic environments. The ductile zinc plating withstands cold pressing and bending without chipping or damaging the coating, supporting long‑term indoor and outdoor use.
Easy Installation
Thanks to the petal‑style design, you only need pliers (e.g., offset pliers) to grip the base of the nut. The nut sleeve will expand like blooming petals. Next, tighten the screw, which causes further expansion, locking the nut securely onto the thin sheet.
Wide Application
This petal nut set works great for automotive fastening, steel housing panel joining, plastic chassis assembly and more. It is especially suited for mounting objects onto thin steel plates, square tubing and other thin‑wall materials.
