The Avdel® Stavex® Steel Rivet is a multi-grip, high-strength breakstem fastener that is produced in both steel and stainless steel to meet assembly requirements. This blind rivet can replace several grip fasteners, thereby reducing fastener inventory and simplifying stock control.

With good hole fill and a large bulbing tail, this rivet is ideal for use on thin sheet materials. Stavex® can be used to fasten metal to metal, plastic to plastic, metal to plastic, and metal to rear sheet.

Assembly applications include automotive, commercial vehicles, domestic appliances, electronics, electrical equipment, general light industrial, and heating and ventilating.

Available in a stainless steel option for high corrosion resistance and for applications requiring elevated temperatures.
