Countersunk Head Inner Lock Structural Blind Rivets

Countersunk Head Inner Lock Structral Blind Rivets

Countersunk Head Structural Blind Rivets feature a countersunk head that sits flush with the material surface after installation. Structural blind rivet is an ideal choice for applications that require a combination of structural strength, vibration resistance, and multi-grip capability in blind side situations. 

This breakstem fastener provides exceptional hole fill and forms completely sealed joints that withstand vibrations. Moreover, it effectively seals wide gaps and restricts sheet movement. Its superior shear and tensile strength also enable the utilization of fewer rivets in each assembly.

The structural rivet is commonly used in diverse industries including automotive, cabinets and enclosures, commercial vehicles, domestic appliances, and heating and ventilating. Its effectiveness in joining metal components together, as well as metal and plastic, makes it a versatile fastening solution for different assembly needs.
