TKW Fasteners Pvt Ltd. Manufactures Solid Rivets. TKW Fasteners Pvt Ltd. Is an ISO 9001: 2008 certified company. The Solid Rivets are used in applications where reliability and safety count. A typical application for solid rivets can be found within the structural parts of aircraft. Setting the rivet is achieved by passing the rivet through the material to be fixed and then either deforming the end of the shank or fitting a non return washer such as a "starlock". Deformation can be achieved crudely by hammering or in a more controlled fashion either by using a press or spin riveting.
