Revolution in Fasteners Helps Bridge the Gap 
to Greener Vehicles

With auto sales down as much as 40 percent, it can feel to some like the industry is coming apart. But a "revolution in fasteners" may soon help bridge the gap to greener vehicles, while increasing sales and lowering recall and warranty rates.
