Aluminium Steel Big Head Blind Rivet

An Aluminium Steel Big Head Blind Rivet consists of an aluminium alloy shank and a steel big head. The shank is usually made of high - quality aluminium alloy, which offers good corrosion resistance and lightweight characteristics. The big head, made of steel, provides enhanced strength and durability. It also has a mandrel inside. When the rivet is installed, the mandrel is pulled to expand the shank and form a tight connection.

The Aluminium Steel Big Head Blind Rivet is a high-strength fastening solution designed for applications requiring a wide bearing surface and reliable clamping force. It consists of an aluminium body and a steel mandrel, combining lightweight properties with enhanced tensile strength. The large head design distributes load effectively, reducing the risk of material pull-through and providing a secure hold on softer or brittle substrates.
