Anti-shingle rivets are provided. The anti-shingle rivets comprise a head portion comprising an outer edge configured to inhibit shingling in a rivet delivery system and a shank extending from the head portion.

In a fastening method and fastening apparatus, workpieces are fastened using a fastener made of a thermoplastic polymer comprising carbon fibers. The method and apparatus involve induction heating of the carbon fibers to soften the thermoplastic polymer and then plastically deforming axial ends of the fastener using a die or dies to form first and second heads while a shaft body or a shaft part of the thermoplastic polymer comprising the carbon fibers is inserted through respective through holes formed in the workpieces.

A connecting component with built-in radio frequency identification element which includes a main body and a radio frequency identification element is provided. The main body has a cylindrical body part and a head, wherein the body part has a connecting end and a free end; the head is connected to the connecting end, and the maximum outer diameter thereof is greater than an outer diameter of the body part; the head has an accommodating hole, and an opening of the accommodating hole is formed at a top of the head; the radio frequency identification element can be inserted into the accommodating hole. When the connecting component is used to fixedly connect the rigid object, the radio frequency electronic component provides a space to store database; with the radio frequency identification reader, industry can read the data at any time during the inspection or the maintenance stages, which improves the convenience of obtaining data and the efficiency of operation.

A different material joining structure has: a first panel made of a first metal material; a second panel made of a second metal material that has a higher conductivity than that of the first panel, is different from the first metal material, and at least a part of which faces the first panel; and a rivet for joining the first panel and the second panel, wherein the rivet is made of the first material, and includes a head portion that is embedded in the second panel in a non-penetrating manner and a bottom portion that abuts on the first panel, and wherein a nugget portion as a joint portion is disposed between the first panel and the bottom portion, the nugget portion being formed by resistance welding the rivet to the first portion with the rivet disposed between the first panel and the second panel.

A fastening apparatus includes a fastening device (1, 3) that heats in a non-contacting state, and then applies pressure to, a shaft part (11b) or shaft body (111) while it is inserted through the through holes (W10, W20) of workpieces (W1, W2), thereby forming at least a second head part (11c) of a fastener (11). The fastening device (1, 3) includes: a fastening die (15) that forms the second head part (11c); and a shaft-part pressure-applying device (9) that applies the pressure to the fastening die (15). A determining device (5) determines whether the fastener (11) is defective or not by calculating a load curve defined by the time and the load during which the pressure was applied and then determining whether an amount of change per unit of time in the load curve after a reference load has been exceeded is within a range of a predetermined reference value.
