The Avdel® Q Rivet structural breakstem fastener has a high shear and tensile strength. The Q Rivet features an interference lock, improving strength. It also has a weatherproof feature thanks to the splined stem design which plugs the entire length of the shell.

These structural breakstem fasteners can be used to fasten metal to metal, metal to plastic, and thin rear sheet. Assembly applications include automotive, warehouse racking, ladders, building industries, commercial vehicles, domestic appliances, and heating and ventilation.

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