The preferred embodiment of a double ended stud fastening system includes a first segment for engaging a plastic component, a second threaded segment for engaging a nut and a lateral projection disposed between the segments. In another aspect of the present invention, the first segment is threaded and the lateral projection is a flange.

Double ended stud fastening system

A blind rivet set verification system for setting a blind rivet assessing the acceptability of the rivet set. The system includes a remote intensified rivet setting tool and computer hardware and software. The tool comprises a displacement transducer that produces a displacement signal and a pressure transducer that produces a pressure signal. The transducers are connected to the computer which receives the distinct signals. These signals are interpreted to plot a displacement-versus pressure waveform and to determine the velocity of the movement of an air piston that responds to the rivet set by hydraulic pressure. Using the combined date of the velocity waveform and the displacement-versus pressure waveform, the breakload is identified and compared against predetermined ideal data to assess the acceptability of the set. The displacement reading at break is corrected for jaw slippage and offset of the air piston.

Blind rivet set verification system and method

A blind rivet set verification system for setting a blind rivet and assessing the acceptability of the rivet set by measuring and comparing the length of the spent mandrel stem. The system includes a rivet setting apparatus and a programmed system control circuit. The apparatus includes a rivet setting tool, a mandrel stem collection box, and a collection tube connecting the tool and the box. The spent mandrel stems pass from the rivet tool to the collection box through the tube. Along the collection tube are provided a pair of sensors. The sensors are positioned in relatively close proximity to each other and to the box and provide the control circuit with information required to identify and compare mandrel stem length.
